C++-Package examples broken #17514
Description
Description
Compiling clean checkout from github causes multiple undefined reference linker errors.
This kind of errors usually happen if compilation units are linked together that have been compiled with different C++ standards.
Error Message
/usr/bin/ld: libmxnet.a(c_api.cc.o): in function MXNDArrayReshape': c_api.cc:(.text+0x56a7): undefined reference to std::__cxx11::basic_ostringstream<
To Reproduce
git clone --recursive https://github.com/olk/incubator-mxnet/
cd incubator-mxnet/
mkdir build && cd build
cmake -DUSE_NCCL=1 -DUSE_CPP_PACKAGE=1 -DCMAKE_BUILD_TYPE=Release -GNinja ..
ninja -v -j 32
What have you tried to solve it?
The issue was introduced by commit:
230ceee Switch to modern CMake CUDA handling (#17031)
The sources can be successfully compiled and linked with ffeebe4 fix int8 add ut (#17166) as HEAD (== the commit before 230ceee).
