Re: Bug #1619: apxs and --with-system-regex doesn't combine, causing crash

HI, I have now experimented a bit more with this. I have taken down some patches to php.h and configure.in from CVS regarding compilation with apxs. I think part of the problem with the autoconf logic around --with-system-regex is because it is sometimes a three way choice, not a two way choice. When compiling php as a cgi-program, there are the choices of using the bundled Henry Spencer regexp lib og using the GNU based libc code (at least on my system). When compiling php as an Apache module, there are the three posibilities of using the bundled HS lib, of using the HS lib in apache (if configured), or of using the libc version. Or, the other way around: If apache is compiled to use the libc regexps, there are two choices for php, but if apache is compiled with --enable-rule=WANTHSREGEX, there are three posibilities. The changes made by Sascha Schumann in CVS doesn't handle the three way choice. I compiled apache with HSREGEX and php with --with-system-regex, but then configure took the bundled regex anyway. Now I have apache with its own regex code, php with its own and libc regexps unused. Currently (with the cvs change) the confgure.in code is like (in some home made pseudo code: if using apxs if apache uses hsregex use bundled regex else use libc endif else if with-system-regex == no use bundled regex else use libc endif endif I think something like this would be more appropriate, causing --with-system-regex to mean whatever apache uses, when php is compiled as module. If using apxs if with-system-regex == no use bundled regex else /* do as apache does */ if apache uses hsregex use apache's regex code else use libc endif endif else if with-system-regex == no use bundled regex else use libc endif endif Whether --with-system-regex should be interpreted like that is up to you the developers. Other interpretations could be made. I hope this is of a little help.
