Output build options for python c/c++ extensions or embedding
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --extension-suffix ] [ --abiflags ] [ --help ]
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically (at run time) into the interpreter.
--abiflags
print the the ABI flags as specified by PEP 3149.
--cflags
print the C compiler flags.
--ldflags
print the flags that should be passed to the linker.
--includes
similar to --cflags but only with -I options (path to python header files).
--libs
similar to --ldflags but only with -l options (used libraries).
--prefix
prints the prefix (base directory) under which python can be found.
--exec-prefix
print the prefix used for executable program directories (such as bin, sbin, etc).
--extension-suffix
print the extension suffix used for binary extensions.
--help
print the usage message.
To build the singe-file c program prog against the python library, use
gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp
The same in a makefile:
CFLAGS+=$(shell python-config --cflags)
LDFLAGS+=$(shell python-config --ldflags)
all: progr
To build a dynamically loadable python module, use
gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so
