parameter setting problem

[jtwhu]

hello! prof.Hu
I'm having some problems when using your code.
The instructions I use are as follows

sh build.sh
cd build
ninja install 

the errors are as follows:

ninja -v

I tried to copy the feature.h and stdc-predef.h in /usr/include/ to /usr/include/x86_64-linux-gnu/ according to the online method, but it does't work.
I think this parameters below which are $CONDA_PREFIX and $CONDA_PREFIX/$HOST/sysroot in build.sh need to be modified, but I haven't found relevant information about them.

cmake -GNinja \
      -DCMAKE_PREFIX_PATH=$CONDA_PREFIX \  # 参数一
      -DCMAKE_SYSROOT=**$CONDA_PREFIX/$HOST/sysroot\  # 参数二
      -DCMAKE_BUILD_TYPE=Debug \

      -DMosek_LIBRARY_RELEASE=/home/lml/Desktop/mosek/9.1/tools/platform/linux64x86/bin/libmosek64.so \
      -DMosek_LIBRARY_DEBUG=/home/lml/Desktop/mosek/9.1/tools/platform/linux64x86/bin/libmosek64.so \
      ../

Do you have a solution?

I prefer to use conda virtual environment to isolate the compiler and library issue. You should create a anaconda environment and install compiler in the conda environment. I think no further dependencies (except for Mosek) is required for the demo.
