我在强制 CMake 使用 MSVS 链接器而不是 MinGW 链接器时遇到了问题。为了在 MSYS 中支持 MSVC,我实现了一个 bash 脚本,强制 CMake 使用 MSVC 编译器创建 NMake 文件:
cmake -G "NMake Makefiles" -DMSVC=true -DCOMPILER_ROOT=$COMPILER_ROOT -DCMAKE_PROFILE=$CMAKE_PROFILE -DCMAKE_BUILD_TYPE=$CMAKE_DEBUG -DCMAKE_CXX_LINKER=$COMPILER_ROOT/bin/linker.exe
CMake 正确使用 MSVC 编译器并按预期创建 NMake 文件:
$ sh build.sh -msvc /c/binrev/development/vs2010/VC -p
removing CMakeCache.txt
removing temporary directory CMakeFiles
Create MSVC based NMake files.
-- The C compiler identification is MSVC
-- The CXX compiler identification is MSVC
-- Check for CL compiler version

-- Detecting CXX compiler ABI info - done
Execute: brCore.cmake
Linker path CMAKE_CXX_LINKER: c:/binrev/development/vs2010/VC/bin/link.exe
但是在调用 nmake 时,CMAKE 仍然使用 MinGW 链接器:
Linking CXX shared library bin\brCore.dll
c:\binrev\development\mingw\bin\ld.exe: unrecognized option '-Wl,--enable-auto-import'
c:\binrev\development\mingw\bin\ld.exe: use the --help option for usage information
LINK failed. with 1
NMAKE : fatal error U1077: "c:\binrev\development\cmake\bin\cmake.exe": Rückgabe-Code "0xffffffff"
Stop.
NMAKE : fatal error U1077: "c:\binrev\development\vs2010\VC\BIN\nmake.exe": Rückgabe-Code "0x2"
Stop.
NMAKE : fatal error U1077: "c:\binrev\development\vs2010\VC\BIN\nmake.exe": Rückgabe-Code "0x2"
Stop.
在 CMakeCache 中调用 bash shell 脚本后,将设置 MinGW 链接器而不是 MSVC 链接器:
//Path to a program.
CMAKE_LINKER:FILEPATH=c:/binrev/development/mingw/bin/ld.exe
好的,我发现我必须设置 CMAKE_LINKER 变量而不是 CMAKE_CXX_LINKER 以获得正确的依赖关系。但现在我又失败了:
Linking CXX shared library bin\brCore.dll
Das System kann die angegebene Datei nicht finden
mt.exe : general error c10100b1: Failed to load file "bin\brCore.dll". Das System kann die angegebene Datei nicht finden.
MT failed. with 31
有谁知道我做错了什么?谢谢你的帮助。
最好的问候,地狱犬
