[Bug ld/11006] New: A "relaxed" link order of libraries is requested for improved compatibilty
23 Nov 2009 19:45:55 -0000
The GNU ld linker requires the user to specify libraries after any object
files which use them. For example:
$ cat main.c
$ gcc -c sub.c
$ ar rv libsub.a sub.o
ar: creating libsub.a
a - sub.o
$ gcc -L . -lsub main.c ### FAILS !!!
/tmp/cccN9Qxp.o: In function `main':
main.c:(.text+0xa): undefined reference to `sub'
collect2: ld returned 1 exit status
$ gcc main.c -L . -lsub ### WORKS !!!
The linking order requirement is not needed by AIX, so this has been an issue
for users migrating from an AIX system to Linux. This enhancement bug is being
submitted for the benefit of these users.
I am aware of the following workaround:
$ gcc -Wl,--start -lsub -L. main.c -Wl,--end
