Hi everyone, a couple of modules have additional external dependencies:
mod_deflate: zlib mod_lua: lua mod_serf: serf mod_socache_dc: distcache At the moment, the compiled modules do not contain any RPATH/RUNPATH info except when the libraries themselves are installed as libtool libraries, i.e. have accompanying *.la files. The original distcache, zlib and lua distributions by default do not install .la libtool files. It is of course possible, that distros provide such files. I'd like to get the RPATH/RUNPATH included in the modules so that one doesn't have to juggle with LD_LIBRARY_PATH or LoadFile when loading those modules. If the libtool .la files are installed for the dependency libs, the RPATH/RUNPATH automatically gets added by libtool during module linking. If it is not, we could add "-R ..." when calling libtool. On Solaris we already add the "-R ..." unconditional via the "ap_platform_runtime_link_flag" variable. Thsi goes back to at least 2001 and hasn't been used on any other platform since then. On other Unix/Linux platforms we seem to assume that .la files are present or users add LD_LIBRARY_PATH or LoadFile. Since I don't wont to get into the business of writing even longer dependency checking macros to find out, whether a .la file for a lib exists or not, I suggest to always add the -R ... flags to the module LDADD for the modules mentioned above. As a consequence we would also remove the then no longer needed "ap_platform_runtime_link_flag". Last remark: of course the "-R ..." will only be added if the libs are installed in non-default locations, i.e. if --with-LIB=DIR is given. Any objections? Regards, Rainer
