Telling gcc directly to link a library statically
Use -l:
instead of -l
. For example -l:libXYZ.a
to link with libXYZ.a
. Notice the lib
and .a
are written out, as opposed to -lXYZ
which would auto-expand to libXYZ.so
/libXYZ.a
.
It is an option of the GNU ld
linker:
-l namespec
... If namespec is of the form:filename
,ld
will search the library path for a file called filename, otherwise it will search the library path for a file calledlibnamespec.a
. ... on ELF ... systems,ld
will search a directory for a library calledlibnamespec.so
before searching for one calledlibnamespec.a
. ... Note that this behavior does not apply to:filename
, which always specifies a file called filename."
(Since binutils 2.18)
Note that this only works with the GNU linker. If your ld
isn't the GNU one you're out of luck.
You can add .a file in the linking command:
gcc yourfiles /path/to/library/libLIBRARY.a
But this is not talking with gcc driver, but with ld
linker as options like -Wl,anything
are.
When you tell gcc or ld -Ldir -lLIBRARY
, linker will check both static and dynamic versions of library (you can see a process with -Wl,--verbose
). To change order of library types checked you can use -Wl,-Bstatic
and -Wl,-Bdynamic
. Here is a man page of gnu LD: http://linux.die.net/man/1/ld
To link your program with lib1, lib3 dynamically and lib2 statically, use such gcc call:
gcc program.o -llib1 -Wl,-Bstatic -llib2 -Wl,-Bdynamic -llib3
Assuming that default setting of ld is to use dynamic libraries (it is on Linux).
