.SH "NAME"
ligcc \- Wrapper around gcc to create more portable apps
.SH "SYNOPSIS"

\fBligcc\fR [\fBOPTION \&.\&.\&.\fR]
.SH "DESCRIPTION"
.PP
This manual page documents briefly the
\fBligcc\fR
command\&.
.PP
\fBligcc\fR
is a wrapper around gcc\&. It allows you to create more portable executables by doing three things:
.PP

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
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\&.

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Allows you to easily statically link to any other library\&.

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
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\*(Aqt use libpng directly\&.

.ie n \{\

.el \{\

.IP \(bu 2.3
.\}
Add $ORIGIN/\&.\&./lib to the binary\*(Aqs 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 \*(Aqlib\*(Aq 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\&.

.SH "OPTIONS"
.PP
See the manpage of gcc(1) for more information about possible options\&.
.PP
There are also several environment variables available to modify ligcc\*(Aqs behavior check the documentation for more information\&.
.SH "SEE ALSO"
.PP
lig++ (1), gcc(1)\&.
