dnl @synopsis CHECK_LIBPCRE([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
|

|
dnl
|
||
|
|
dnl This macro searches for an installed libpcre library. If nothing
|
||
|
|
dnl was specified when calling configure, it searches first in /usr/local
|
||
|
|
dnl and then in /usr. If the --with-libpcre=DIR is specified, it will try
|
||
|
|
dnl to find it in DIR/include/pcre.h and DIR/lib/libpcre.a. If --without-libpcre
|
||
|
|
dnl is specified, the library is not searched at all.
|
||
|
|
dnl
|
||
|
|
dnl It defines the symbol HAVE_LIBPCRE if the library is found. You should
|
||
|
|
dnl use autoheader to include a definition for this symbol in a config.h
|
||
|
|
dnl file.
|
||
|
|
dnl
|
||
|
|
dnl Sources files should then use something like
|
||
|
|
dnl
|
||
|
|
dnl #ifdef HAVE_LIBPCRE
|
||
|
|
dnl #include <pcre.h>
|
||
|
|
dnl #endif /* HAVE_LIBPCRE */
