Subject: [PATCH] Define _POSIX_C_SOURCE for crfsuite source files
|
||
|
|
|
||
|
|
gcc-14 has "-Werror=implicit-function-declaration" enabled by default.
|
||
|
|
crfsuite uses posix_memalign which only gets defined when _POSIX_C_SOURCE is
|
||
|
|
defined, so make sure the flag is set when compiling crfsuite.
|
||
|
|
|
||
|
|
On the other hand, openSUSE Tumbleweed has _POSIX_C_SOURCE defined
|
||
|
|
in pyconfig.h, so you must not add "-D_POSIX_C_SOURCE" when compiling
|
||
|
|
the python binding source code. So add it only for the subdir crfsuite.
