With any cmake project with the Visual Studio 10 generator on Windows, a specified but empty CMAKE_TOOLCHAIN_FILE causes problems: c:\QtDev\cmaketest\build>cmake .. -DCMAKE_TOOLCHAIN_FILE= -- Building for: Visual Studio 10 CMake Warning (dev) at build/CMakeFiles/CMakeSystem.cmake:1 (INCLUDE): include() given empty file name (ignored). Call Stack (most recent call first): This warning is for project developers. Use -Wno-dev to suppress it. -- Check for working C compiler using: Visual Studio 10 CMake Warning (dev) at C:/QtDev/cmaketest/build/CMakeFiles/CMakeSystem.cmake:1 ( INCLUDE): include() given empty file name (ignored). Call Stack (most recent call first): CMakeLists.txt:2 (PROJECT) This warning is for project developers. Use -Wno-dev to suppress it. -- Check for working C compiler using: Visual Studio 10 -- works -- Detecting C compiler ABI info CMake Warning (dev) at C:/QtDev/cmaketest/build/CMakeFiles/CMakeSystem.cmake:1 ( INCLUDE): include() given empty file name (ignored). Call Stack (most recent call first): CMakeLists.txt:2 (PROJECT) This warning is for project developers. Use -Wno-dev to suppress it. -- Detecting C compiler ABI info - done -- Check for working CXX compiler using: Visual Studio 10 CMake Warning (dev) at C:/QtDev/cmaketest/build/CMakeFiles/CMakeSystem.cmake:1 ( INCLUDE): include() given empty file name (ignored). Call Stack (most recent call first): CMakeLists.txt:2 (PROJECT) This warning is for project developers. Use -Wno-dev to suppress it. The problem seems to be if(DEFINED CMAKE_TOOLCHAIN_FILE) set(INCLUDE_CMAKE_TOOLCHAIN_FILE_IF_REQUIRED "include(\"${CMAKE_TOOLCHAIN_FILE}\")") endif() in CMakeDetermineSystem.cmake. I do not know why it does not hit message(FATAL_ERROR "Could not find toolchain file: ${CMAKE_TOOLCHAIN_FILE}") earlier in that file. I also do not know why this does not fail with the NMake makefile generator, or the Unix Makefile generator. https://bugreports.qt-project.org/browse/QTBUG-27087 ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2012-08-31 07:42 Stephen Kelly New Issue ====================================================================== -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
