PYTHON-CONFIG

 

NAME

python-config – output build options for python C/C++ extensions or embedding  

SYNOPSIS

python-config [ –prefix ] [ –exec-prefix ] [ –includes ] [ –libs ] [ –cflags ] [ –ldflags ] [ –extension-suffix ] [ –configdir ] [ –help ]  

DESCRIPTION

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.  

OPTIONS

–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 suffix used for extension modules (including the _d modified for debug builds).

–configdir

prints the path to the configuration directory under which the Makefile, etc. can be found).

–help

print the usage message.

 

EXAMPLES

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
