Summary: automoc fails when enabling autorcc
Description:
Automoc does not work after initial cmake run when autorcc is enabled.
I created a small example that shows the problem. I created it from
scratch and it instantly fails for me. I get:
error C3861: 'onTst2': identifier not found (moc_main.cpp)
This file is auto-generated and thus was not updated. -> Should not
happen.
I also tried to manually run cmake, it won't help. However, commenting mainx.qrc
helps! Or using qt4_add_resources() and disabling CMAKE_AUTORCC!
Suddenly, the bugtest_automoc target is gone in VS and it compiles
again, even after adding/removing Qt slot functions.
BTW, why is this target called bugtest_automoc and not bugtest_autogen?
The whole thing looks strange as bugtest target still has a
qrc_mainx.cpp.rule but bugtest_automoc also has such a rule.
The bugtest.automoc.rule file properties show no real command:
-----------------
setlocal
cd D:\bugtest\cmake-autogen\build
if %errorlevel% neq 0 goto :cmEnd
D:
if %errorlevel% neq 0 goto :cmEnd
:cmEnd
endlocal & call :cmErrorLevel %errorlevel% & goto :cmDone
:cmErrorLevel
exit /b %1
:cmDone
if %errorlevel% neq 0 goto :VCEnd
-----------------
Is that supposed to actually do something?
I am using Visual Studio 2010. CMake is 3.2.2 but also I tried 3.3-rc1.
Steps to Reproduce:
You need to create a foo.png to get the qrc to actually create the
source file (actually 2nd bug that CMake doesn't warn about a missing file).
First run, comment out the onTst2 slot function (both h and cpp file),
it should build.
Then comment it before 2nd run.
Additional Information:
CMakeLists.txt:
----------------------------------------------
cmake_minimum_required ( VERSION 3.0.2 )
cmake_policy ( VERSION 3.0.2 )
project ( bugtest CXX )
find_package ( Qt4 )
set ( CMAKE_INCLUDE_CURRENT_DIR ON )
set ( CMAKE_AUTOMOC ON )
set ( CMAKE_AUTORCC ON )
add_executable ( bugtest
main.cpp
mainx.qrc
)
target_link_libraries ( bugtest Qt4::QtCore )
----------------------------------------------
main.h:
----------------------------------------------
#include <QObject>
class tst1 : public QObject
{
Q_OBJECT
public slots:
void onTst1();
//void onTst2();
};
----------------------------------------------
main.cpp:
----------------------------------------------
#include "main.h"
void tst1::onTst1()
{
}
// void tst1::onTst2()
// {
// }
int main( int argc, char **argv)
{
return 0;
}
----------------------------------------------
mainx.qrc:
----------------------------------------------
<!DOCTYPE RCC><RCC version="1.0">
<qresource>
<file>foo.png</file>
</qresource>
</RCC>
