LD_LIBRARY_PATH in Conda environment

Question

I create a Conda environment ( myenv ), and build a Python extension (using distutils ) in this env. My library uses some libraries which exist on both /usr/local/lib and /home/user/miniconda3/envs/myenv/lib .

In myenv , LD_LIBRARY_PATH is empty, but ldd mylib.so shows that my library links to libraries in /home/user/miniconda3/envs/myenv/lib . This makes sense but I wonder why it doesn't link to libraries in /usr/local/lib ?

Most likely, you're using the compiler and related toolchain from your conda environment. This toolchain is set up to use the libraries from your conda environment automatically.
