[Bug 458274] Re: unnecassary dependencies of apache2 modules

[jfcgauss]

For instance
ldd -r -u /usr/lib/apache2/modules/mod_ssl.so 2>&1 | grep -v 'undefined symbol:\|lookup error:\|direct dependencies:\|^$'
gives
	/lib/libuuid.so.1
	/lib/librt.so.1
	/lib/libcrypt.so.1
	/lib/libpthread.so.0
	/lib/libdl.so.2
that is, mod_ssl.so module (which is a shared library) has been linked during "compile-link" time with the above unnecassary (unused) shared libraries. Either these unnecessary libs (possibly in the gcc command line like "-ldl -lpthread -lcrypt -lrt" etc. during compile-link time) should be removed (that is, mod_ssl build should be fixed) or we should add something like -Wl,--as-needed to mod_ssl build. hope that is clear enough. this is not a showstopper, but these unused dependencies cost time and memory when loading these modules.

actually i had mentioned unused dependency problems of tons of shared
libraries in ubuntu/debian a while back, dont know what happened then.
(hint: man ldd).
