| Summary | 0015013: subsystem windowsce is not set for dll only for exes, this makes dll not loadable on wec2013 (wince8) |
| Description | the subsystem switch for the linker is only set for executables but not for dlls.
this was no problem for ce < wec2013. but wec2013 checks for correct subsystem. you can see this informations using depends.exe from dependancywalker.com
|
| Steps To Reproduce | compile a project containg a dll with a wec2013 sdk. this dll will not be loaded on wec2013. |
| Additional Information | this problem can be fixed with this simple patch:
--- a\share\cmake-3.0\Modules/Platform/Windows-MSVC.cmake
+++ b\share\cmake-3.0\Modules/Platform/Windows-MSVC.cmake

set(WINCE 1)
else()
set(CMAKE_CREATE_WIN32_EXE "/subsystem:windows")
set(CMAKE_CREATE_CONSOLE_EXE "/subsystem:console")
endif()
CMAKE_EXE_LINKER_FLAGS_INIT is inherited by the dll settings but CMAKE_CREATE_WIN32_EXE or CMAKE_CREATE_CONSOLE_EXE is of course not.

Thanks. Placing it in CMAKE_EXE_LINKER_FLAGS will break existing build trees whose cache entry does not already contain it. Since we must pass the flag to all linker calls we should just do so directly. Please try the attached "0001-MSVC-Fix-linking-of-DLLs-on-WinCE-15013.patch". |

OK this should also work.
I did not know cmake needs to support existing build trees when upgrading the cmake version. This is a hard to test feature methinks. Would it not be easier to Check version of the used cake in the build tree and on mismatch, trigger a complete regeneration? That seems more reliable to me. |

Re 0015013:0036349: The language init and compiler detection is re-run for each new CMake version. However, we cannot overwrite or wipe out CMakeCache.txt entries that can be user-specified. CMAKE_EXE_LINKER_FLAGS is among those. There is no reason to let users modify/break addition of the subsystem flag for MSVC/WinCE anyway. |
