Does XGBOOST not support MD runtime Library on MSVC?
I see that we force static runtime for MSVC by calling msvc_use_static_runtime() from cmake/Utils.cmake
e.g.
or CMakeLists.txt#L332
or …/master/src/CMakeLists.txt#L32
With my limited understanding, this creates issue with applications as default runtime is MD and hence resulting into link errors.
I am building XGBOOST as a static c++ library i.e. BUILD_STATIC_LIB = ON
When I try to build my application while linking against this xgboost.lib, I get runtime Library mismatch errors.
e.g.
xgboost.lib(learner.obj) : error LNK2038: mismatch detected for ‘RuntimeLibrary’: value ‘MT_StaticRelease’ doesn’t match value ‘MD_DynamicRelease’ in xyz.obj [C:\dev\projects\hap.xgboost\apps\build\xyz.vcxproj]
…
…
xgboost.lib(random.obj) : error LNK2038: mismatch detected for ‘RuntimeLibrary’: value ‘MT_StaticRelease’ doesn’t match value ‘MD_DynamicRelease’ in xyz.obj [C:\dev\projects\hap.xgboost\apps\build\xyz.vcxproj]
…
(xyz is the name of my test application)
While debugging this, I found the forceful use of static runtime Library in cmake of xgboost, leading to mismatch.
Hence pointed it out.
Please let me know if you need any further information
