I mark this issue as a release blocker: bpo-21536 basically broke the compilation of all applications which embed Python. IMHO this issue is the best solution to fix it. > I don't understand the need for this. Oh. Let me explain this issue differently. There are two use cases for libpython: * Build a C extension and load it in Python: use case called "pyext" by waf * Embed Python into an application: use case called "pyembed" by waf My bpo-21536 broke waf "pyembed" which fails to detect Python. waf "pyembed" creates a C program which calls Py_Initialize(), but the linker fails to locate Py_Initialize() symbol. To embed Python into an application, we really need to link the application to libpython: we need -lpython3.8. In Python 3.7, "pyext" and "pyembed" use cases were covered both by default "python3.7-config --libs" and "pkg-config python3.7 --libs" configuration. In Python 3.8, we now have to distinguish both use cases and provide *different* configuration depending if binary must be linked to libpython or not.
