make command in windows 10 generating the error:-CodePudding

Here's the code, I am trying to compile using make command in command prompt.

nvcc := "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.0/bin/nvcc"
cudalib := "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.0/extras/CUPTI/lib64"
cudainclude := "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.0/include"
tensorflow := C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.29.30133/bin/Hostx64/x64

TF_CFLAGS := $$(python -c 'import tensorflow as tf; print(" ".join(tf.sysconfig.get_compile_flags()))') 
TF_LFLAGS := $$(python -c 'import tensorflow as tf; print(" ".join(tf.sysconfig.get_link_flags()))') 


all: tf_nndistance_so.so
clean:
    rm -rf *.o *.so
.PHONY : all clean

tf_nndistance_so.so: tf_nndistance_g.o tf_nndistance.cpp
    g   -std=c  11 -shared tf_nndistance.cpp tf_nndistance_g.o -o tf_nndistance_so.so -fPIC $(TF_CFLAGS) $(TF_LFLAGS) -O2

tf_nndistance_g.o: tf_nndistance_g.cu
    $(nvcc) -D_GLIBCXX_USE_CXX11_ABI=0 -std=c  11 -c -o tf_nndistance_g.o tf_nndistance_g.cu -I $(tensorflow) -DGOOGLE_CUDA=1 -x cu -Xcompiler -fPIC -O2

But getting the following error:

"C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.0/bin/nvcc" -D_GLIBCXX_USE_CXX11_ABI=0 -std=c  11 -c -o tf_nndistance_g.o tf_nndistance_g.cu -I C:/"Program Files (x86)"/"Microsoft Visual Studio"/2019/Community/VC/Tools/MSVC/14.29.30133/bin/Hostx64/x64 -DGOOGLE_CUDA=1 -x cu -Xcompiler -fPIC -O2
nvcc fatal   : Cannot find compiler 'cl.exe' in PATH
make: *** [Makefile:19: tf_nndistance_g.o] Error 1

Any suggestions are welcome.

Thank you.

Install Visual Studio.

You will need to add the folder containing the "cl.exe" file to your path environment variable. For example:

C:\Program Files\Microsoft Visual Studio 10.0\VC\bin

go to My Computer -> Properties -> Advanced System Settings -> Environment Variables. Here look for "PATH" in the list, and add the path above (or whatever is the location of your cl.exe).

The immediate problem

You need to set your VStudio (2019 that you already have installed) paths.
A common way of doing that is invoking vcvarsall.bat: "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" x64.

The bigger problem

You are mixing compilers:

CUDA Toolkit uses (by default) VStudio (native) compiler (cl.exe)
You are using g .exe

This is a bad idea you should stick to one compiler (cl - as instructed in previous section). Note that some flags that you use are not compatible.
Or instruct CUDA to use g (don't know what build toolchain it belongs to, and don't know if possible).
