ligcc - Wrapper around gcc to create more portable apps
ligcc [OPTION ...]
This manual page documents briefly the ligcc command.
ligcc is a wrapper around gcc. It allows you to create more portable executables by doing
· Forces the linker to link against older glibc symbols. Users who are using an older
version of glibc will no longer get "undefined symbol GLIBC_2.4 in /lib/libc.so"-style
· Allows you to easily statically link to any other library.
· Automatically removes bogus dependencies. For example, your program uses libfoo.
libfoo uses libpng internally, but your app does not. Yet the pkg-config file for
libfoo specifies "-lfoo -lpng" is linker parameters. And tadaa - you now have a bogus
dependency on libpng! LiGCC automatically removes the -lpng for you if your app
doesn't use libpng directly.
· Add $ORIGIN/../lib to the binary's library search path. $ORIGIN is the directory in
which the binary exists. This ensures that your binary can find library dependencies
which are placed in the 'lib' folder under the same prefix. You might want to install
custom libraries into /lib. If you set $APBUILD_PROJECTNAME, ligcc will also add
$ORIGIN/../lib/$APBUILD_PROJECTNAME to the library search path.
See the manpage of gcc(1) for more information about possible options.
There are also several environment variables available to modify ligcc's behavior check
the documentation for more information.
