Make 2 sub make ошибка 2

Build Error. make fails with Error 2 #7670

The build fails at make step with the error:

More information below.

Below error that shows in the middle of the make process, but make process continues to progress:

The make error points to line 141 of MakeFile. Clipped code from that file with line numbers as comments:

Not sure where to proceed from here. Thanks.

Edit1:
Ran again with make -d -j$(nproc) . Got the error:

Edit2:
Above seems error due to the fox library so adding below lines from CMakeCache.txt that represent fox paths:

/repos/fox-1.6.57/build/include //Path to a library. FOX_LIBRARY:FILEPATH=

The text was updated successfully, but these errors were encountered:

The errors look gtest related. The easiest workaround is to disable gtest. You can do so by setting GTEST_LIBRARY:FILEPATH= (the empty string) in your CMakeCache.txt and run make again. Did you do something to fix the missing header file error for the second run?

I experienced the same type of error, i.e. «make: *** [Makefile:141: all] Error 2». But based on the information I got from this page, i.e. «Ran again with make -d -j$(nproc)», my installation/build completed successfully. Thanks very much.

@behrisch
I tried the GTest change you had mentioned. Removed the library path from GTEST_LIBRARY:FILEPATH .
My CMakeCache.txt for relevant lines looks like:

This change is reflected when I run cmake, and now I see:
Could NOT find GTest (missing: GTEST_LIBRARY) .

But during the make -j$(nproc) , the error is:

Did you do something to fix the missing header file error for the second run?

I am not sure what you are refering to.

Update:
I was able to compile it successfully. But sumo still isn’t working.

Makefile error code 2

Here is a list of the more common errors you might see generated by make , and some information about what they mean and how to fix them.

Sometimes make errors are not fatal, especially in the presence of a — prefix on a recipe line, or the -k command line option. Errors that are fatal are prefixed with the string *** .

Error messages are all either prefixed with the name of the program (usually ‘ make ’), or, if the error is found in a makefile, the name of the file and line number containing the problem.

In the table below, these common prefixes are left off.

‘ [ foo ] Error NN ’ ‘ [ foo ] signal description ’

These errors are not really make errors at all. They mean that a program that make invoked as part of a recipe returned a non-0 error code (‘ Error NN ’), which make interprets as failure, or it exited in some other abnormal fashion (with a signal of some type). See Errors in Recipes.

If no *** is attached to the message, then the sub-process failed but the rule in the makefile was prefixed with the — special character, so make ignored the error.

‘ missing separator. Stop. ’ ‘ missing separator (did you mean TAB instead of 8 spaces?). Stop. ’

This means that make could not understand much of anything about the makefile line it just read. GNU make looks for various separators ( : , = , recipe prefix characters, etc.) to indicate what kind of line it’s parsing. This message means it couldn’t find a valid one.

One of the most common reasons for this message is that you (or perhaps your oh-so-helpful editor, as is the case with many MS-Windows editors) have attempted to indent your recipe lines with spaces instead of a tab character. In this case, make will use the second form of the error above. Remember that every line in the recipe must begin with a tab character (unless you set .RECIPEPREFIX ; see Special Variables). Eight spaces do not count. See Rule Syntax.

‘ recipe commences before first target. Stop. ’ ‘ missing rule before recipe. Stop. ’

This means the first thing in the makefile seems to be part of a recipe: it begins with a recipe prefix character and doesn’t appear to be a legal make directive (such as a variable assignment). Recipes must always be associated with a target.

The second form is generated if the line has a semicolon as the first non-whitespace character; make interprets this to mean you left out the «target: prerequisite» section of a rule. See Rule Syntax.

‘ No rule to make target ` xxx ‘. ’ ‘ No rule to make target ` xxx ‘, needed by ` yyy ‘. ’

This means that make decided it needed to build a target, but then couldn’t find any instructions in the makefile on how to do that, either explicit or implicit (including in the default rules database).

If you want that file to be built, you will need to add a rule to your makefile describing how that target can be built. Other possible sources of this problem are typos in the makefile (if that file name is wrong) or a corrupted source tree (if that file is not supposed to be built, but rather only a prerequisite).

‘ No targets specified and no makefile found. Stop. ’ ‘ No targets. Stop. ’

The former means that you didn’t provide any targets to be built on the command line, and make couldn’t find any makefiles to read in. The latter means that some makefile was found, but it didn’t contain any default goal and none was given on the command line. GNU make has nothing to do in these situations. See Arguments to Specify the Makefile.

‘ Makefile ` xxx ‘ was not found. ’ ‘ Included makefile ` xxx ‘ was not found. ’

A makefile specified on the command line (first form) or included (second form) was not found.

‘ warning: overriding recipe for target ` xxx ‘ ’ ‘ warning: ignoring old recipe for target ` xxx ‘ ’

GNU make allows only one recipe to be specified per target (except for double-colon rules). If you give a recipe for a target which already has been defined to have one, this warning is issued and the second recipe will overwrite the first. See Multiple Rules for One Target.

‘ Circular xxx yyy dependency dropped. ’

This means that make detected a loop in the dependency graph: after tracing the prerequisite yyy of target xxx , and its prerequisites, etc., one of them depended on xxx again.

‘ Recursive variable ` xxx ‘ references itself (eventually). Stop. ’

This means you’ve defined a normal (recursive) make variable xxx that, when it’s expanded, will refer to itself ( xxx ). This is not allowed; either use simply-expanded variables (‘ := ’ or ‘ ::= ’) or use the append operator (‘ += ’). See How to Use Variables.

‘ Unterminated variable reference. Stop. ’

This means you forgot to provide the proper closing parenthesis or brace in your variable or function reference.

‘ insufficient arguments to function ` xxx ‘. Stop. ’

This means you haven’t provided the requisite number of arguments for this function. See the documentation of the function for a description of its arguments. See Functions for Transforming Text.

‘ missing target pattern. Stop. ’ ‘ multiple target patterns. Stop. ’ ‘ target pattern contains no `%’. Stop. ’ ‘ mixed implicit and static pattern rules. Stop. ’

These errors are generated for malformed static pattern rules (see Syntax of Static Pattern Rules). The first means the target-pattern part of the rule is empty; the second means there are multiple pattern characters ( % ) in the target-pattern part; the third means there are no pattern characters in the target-pattern part; and the fourth means that all three parts of the static pattern rule contain pattern characters ( % )–the first part should not contain pattern characters.

If you see these errors and you aren’t trying to create a static pattern rule, check the value of any variables in your target and prerequisite lists to be sure they do not contain colons.

‘ warning: -jN forced in submake: disabling jobserver mode. ’

This warning and the next are generated if make detects error conditions related to parallel processing on systems where sub- make s can communicate (see Communicating Options to a Sub- make ). This warning is generated if a recursive invocation of a make process is forced to have ‘ -j N ’ in its argument list (where N is greater than one). This could happen, for example, if you set the MAKE environment variable to ‘ make -j2 ’. In this case, the sub- make doesn’t communicate with other make processes and will simply pretend it has two jobs of its own.

‘ warning: jobserver unavailable: using -j1. Add `+’ to parent make rule. ’

In order for make processes to communicate, the parent will pass information to the child. Since this could result in problems if the child process isn’t actually a make , the parent will only do this if it thinks the child is a make . The parent uses the normal algorithms to determine this (see How the MAKE Variable Works). If the makefile is constructed such that the parent doesn’t know the child is a make process, then the child will receive only part of the information necessary. In this case, the child will generate this warning message and proceed with its build in a sequential manner.

‘ warning: ignoring prerequisites on suffix rule definition ’

According to POSIX, a suffix rule cannot contain prerequisites. If a rule that could be a suffix rule has prerequisites it is interpreted as a simple explicit rule, with an odd target name. This requirement is obeyed when POSIX-conforming mode is enabled (the .POSIX target is defined). In versions of GNU make prior to 4.3, no warning was emitted and a suffix rule was created, however all prerequisites were ignored and were not part of the suffix rule. Starting with GNU make 4.3 the behavior is the same, and in addition this warning is generated. In a future version the POSIX-conforming behavior will be the only behavior: no rule with a prerequisite can be suffix rule and this warning will be removed.

Where can I find a list of ‘make’ error codes?

I am trying to compile a program written in Fortran using make (I have a Makefile and, while in the directory containing the Makefile, I type the command $ make target , where «target» is a system-specific target specification is present in my Makefile. As I experiment with various revisions of my target specification, I often get a variety of error messages when attempting to call make . To give a few examples:

Do you know how I can find a list of what the error codes, such as «Error 126» and «Error 2,» mean? I found this thread on another website, but I am not sure what the reply means. Does it mean that there is no system-independent meaning of the make error codes? Can you please help me? Thank you.

2 Answers 2

The error codes aren’t from make: make is reporting the return status of the command that failed. You need to look at the documentation of each command to know what each status value means. Most commands don’t bother with distinctions other than 0 = success, anything else = failure.

In each of your examples, ./dpp cannot be executed. When this happens, the shell that tried to invoke it exits with status code 126 (this is standard behavior). The instance of make that was running that shell detects a failed command (the shell) and exits, showing you Error 126 . That instance of make is itself a command executed by a parent instance of make, and the make utility returns 2 on error, so the parent make reports Error 2 .

The failure of your build is likely to stem from test: too many arguments . This could be a syntax error in the makefile, or it could be due to relying on bash-specific features when you have a /bin/sh that isn’t bash. Try running make SHELL=/bin/bash target or make SHELL=/bin/ksh target ; if that doesn’t work, you need to fix your makefile.

Makefile:160: recipe for target ‘all’ failed make: *** [all] Error 2 #7652

STOP READING NOW

If you get the error message from the caption, because it is useless and too generic (are you sure that you build OpenCV library and not other make project?).
Reason of your build problem is somewhere above this line, you need to grab it instead.
To get right error message you should run «make» in verbose mode:

(without any -j options to prevent message lines mess)

System information (version)

• OpenCV => 3.1
• Operating System / Platform => Elementary OS (Loki)
• Compiler => make

Detailed description

• When I did just cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. , make -j4 worked all right«`
• When I tried to make -j4 VERBOSE=1 with Examples and Modules, I got this error

Steps to reproduce

• Downloaded opencv and opencv_contrib
• Then cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=

/Programs/anaconda3/pkgs/opencv_contrib/modules -D INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_IPP=OFF ..

The text was updated successfully, but these errors were encountered:

What more information should I provide? @alalek

Detailed build log with failed command should help to reproduce problem ( make VERBOSE=1 ).

To receive proper build log you should run make without -j4 . Current log cut doesn’t contain failed command and error message.

@pcuci did not work. Any other alt?

Probably there is unsupported system protobuf installation with other compiler flags ( c++11 is not used by default in OpenCV).
Try to run with this CMake option: -DBUILD_LIBPROTOBUF_FROM_SOURCES=ON or just disable dnn module ( -DBUILD_opencv_dnn=OFF ).

Latest code (opencv and opencv_contrib) should work fine without additional options. It just ignores system protobuf installations. You need to build from scratch (clean build directory).

So I’m trying to run the open-source code from this research paper, but I keep getting [make] Error 2. The makefile for the code was thankfully provided so I all I did was run the make command when I was in the folder that contained the makefile.

I’m new to all of this, I got everything from the internet, so I apologize if I’m a bit ignorant. I’m trying to learn, please be patient (:

QuantumHoneybees-MacBook-Pro:femflip2 Joe$ make 

Edit:: I’ve narrowed it down to the makefile in lines 36-44 there is something wrong with what is written. I unfortunately have zero experience with writing makefiles, so I don’t know how to fix it. I tried messing around with some lines’ indentation because some other threads seem to have that issue, but to no avail.

Hello everyone, I’m new to qt embedded and I have problem with make command.

I have an ARM-based (Rockchip RK3288, ARM Cortex-A17 CPU, Mali-T760 MP4 (T764) GPU)motherboard and I want to cross-compile using it. I use Debian 9 as the operating system on this card, and I use Ubuntu 21.04 on the host PC.

I used this commands:

./configure -static -release -opengl es2 -device linux-jetway-arm-g++ -device-option CROSS_COMPILE=~/linaro/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -no-eglfs -sysroot ~/linaro/sysroot -opensource -confirm-license -prefix /usr/local/qt5li -extprefix ~/linaro/qt5li -hostprefix ~/linaro/qt5 -opensource -confirm-license -skip qtscript -skip qtwayland -skip qtlocation -no-gbm -nomake examples -nomake tests -make libs -pkg-config -no-use-gold-linker -v

My configure command works and I get no errors. Then when I run the make -j4 command I get the following error.

make[2]: Leaving directory '/home/buket/linaro/qt-everywhere-src-5.12.2/qtbase/src/gui'
make[1]: Leaving directory '/home/buket/linaro/qt-everywhere-src-5.12.2/qtbase/src'
make: *** [Makefile:51: sub-src-make_first] Error 2

I also ran the make install command because I thought it wouldn’t cause any problems and this time I got the errors below.

My qmake.conf file:

#
# Generic qmake configuration for building with g++ on arm devices.
#
# A minimal configure line could look something like this:
# ./configure -device arm-generic-g++ -device-option CROSS_COMPILE=arm-linux-gnueabi-

EGLFS_DEVICE_INTEGRATION = none


include(../common/linux_arm_device_post.conf)
load(qt_config)

I think there is a problem with my qmake.conf file as I had to edit it myself. Although I made changes in my configure command, the result did not change and since the motherboard I use is not a common card, I can only research according to its processor. How can I run the make command without getting an error?
