POSIX regex functions required and missing

Question

when i trying to compile an old c source code using msys2 this error happens:

"configure: error: POSIX regex functions required and missing!"

Please any idea? Is that a library that can be added or it's an error related to the code itself?

Have you tried to search in the code for this message to see if it is a error related to the code itself ? — Adam Sinclair, Sep 22 '14 at 13:48
It looks to me like 'configure' is looking for the POSIX regex functions and not finding them. This is happening way before any actual compilation IMHO. — Charlie Burns, Sep 22 '14 at 14:24
@CharlieBurns yes, It seems close. have you any ideas about POSIX regex library? — Reda, Sep 22 '14 at 14:27
You probably need libregex installed and the headers also ( regex.h ). Google libregex. — Charlie Burns, Sep 22 '14 at 14:27
I assume to code uses autoconf. You should have a `configure` script somewhere. Try to find `POSIX regex` in it, and you should find hints about what it needs. — Serge Ballesta, Oct 05 '14 at 10:15

It's not clear whether you want to build an MSYS2 or a native program. Anyway ..

MSYS2 has the following regex libraries. You can search for them yourself via:

pacman -Ss regular

From the mingw{32,64} (i.e. native) repositories:

mingw-w64-{x86_64,i686}-oniguruma
mingw-w64-{x86_64,i686}-pcre

From the msys2 (i.e. Cygwin-like msys-2.0.dll linked) repository:

libpcre
libpcre16
libpcre32
libpcrecpp
libpcreposix
pcre
