Re: [cmake-developers] Empty ERROR_VARIABLE in execute_process
Ok, thanks Brad.
Hello Qt Mailing list,
First i thought this is a bug in CMake but it has appeared that it seems to be
a bug in qmllint:
Here the original question:
when I run qmllint from the command line to test an error I get:
C:\Tests>C:\Qt\5.6\msvc2015\bin\qmllint.exe test.qml
test.qml:1 : Syntax error
C:\Tests>echo %ERRORLEVEL%
-1
C:\Tests>
If I call this from a CMake script
execute_process(COMMAND C:/Qt/5.6/msvc2015/bin/qmllint.exe C:/Tests/test.qml
RESULT_VARIABLE _resVar
OUTPUT_VARIABLE _outVar
ERROR_VARIABLE _errVar
OUTPUT_STRIP_TRAILING_WHITESPACE
ERROR_STRIP_TRAILING_WHITESPACE)
message("_resVar: ${_resVar}")
message("_outVar: ${_outVar}")
message("_errVar: ${_errVar}")
The output is:
1> _resVar: -1
1> _outVar:
1> _errVar:
It seems that the error pipe isn’t read correctly, because _errVar is empty.
And hints?
Regards
Roman

I was able to reproduce it with that, but I also tried this:
add_custom_target(${PROJECT_NAME}-c2
COMMAND C:/Qt/5.6/msvc2015/bin/qmllint.exe
${CMAKE_CURRENT_SOURCE_DIR}/test.qml
)
The output does not appear in this case either. No execute_process
is involved, and qmllint is invoked directly by msbuild. This has
something to do with qmllint changing output behavior when it is
executed inside a VS IDE (MSBuild) build.

I cannot reproduce that. With an empty test.qml file I get: _resVar: -1 _outVar: _errVar: test.qml:1 : Expected token `numeric literal' using the same qmllint version: >c:\Qt\5.6.0\5.6\msvc2015_64\bin\qmllint.exe --version qmllint 1.0 and current CMake 'master'. -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

[cmake-developers] Empty ERROR_VARIABLE in execute_process
Hello,
when I run qmllint from the command line to test an error I get:
C:\Tests>C:\Qt\5.6\msvc2015\bin\qmllint.exe test.qml
test.qml:1 : Syntax error
C:\Tests>echo %ERRORLEVEL%
-1
C:\Tests>
If I call this from a CMake script
execute_process(COMMAND C:/Qt/5.6/msvc2015/bin/qmllint.exe C:/Tests/test.qml
RESULT_VARIABLE _resVar
OUTPUT_VARIABLE _outVar
ERROR_VARIABLE _errVar
OUTPUT_STRIP_TRAILING_WHITESPACE
ERROR_STRIP_TRAILING_WHITESPACE)
message("_resVar: ${_resVar}")
message("_outVar: ${_outVar}")
message("_errVar: ${_errVar}")
The output is:
1> _resVar: -1
1> _outVar:
1> _errVar:
It seems that the error pipe isn’t read correctly, because _errVar is empty.
And hints?
Regards
Roman
