NAME¶
ligcc - Wrapper around gcc to create more portable apps
SYNOPSIS¶
ligcc [OPTION ...]
DESCRIPTION¶
This manual page documents briefly the ligcc command.
ligcc is a wrapper around gcc. It allows you to create more
portable executables by doing three things:
•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 error
messages.
•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.
OPTIONS¶
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.
