[Bug ld/1150] undefined reference to `_mpi_sgi_init'
--- Additional Comments From nickc at redhat dot com 2005-11-10 11:45 --- Subject: Re: undefined reference to `_mpi_sgi_init' Hi Michael, > Okay, I gave it a try to build a testcase. It's included in the attachment. Thanks. I was not able to run all of the tests in your testcase, since I do not have the Irix system libraries available, but I was able to reproduce the linker error message about undefined symbols and I have produced a tentative patch that might allow give you a working GNU linker. The patch does not implement all of the spec for OPTIONAL symbols. I hope that for now this will not be important. The patch also includes a modification to readelf so that it will display the OPTIONAL flag if it is defined in an Irix binary. You do not actually need this part of the patch in order to get a working linker, but I have included it since it is all part of the same problem.

The testcase nwo runs fine with the patched ld:
[EMAIL PROTECTED] ot]$ make bu
as -64 -o start.o start.s
as -64 -o ot.o ot.s
as -64 -o os.o os.s
/usr/local/bin/ld -melf64bmip -o ot-opt-bu /usr/lib64/mips4/crt1.o ot.o
os.o /usr/lib64/mips4/crtn.o -lc
/usr/local/bin/ld -melf64bmip -o ot-noopt-bu /usr/lib64/mips4/crt1.o
ot.o /usr/lib64/mips4/crtn.o -lc
sed -e "s,/\* \(.weak.*\) \*/,\1," ot.s >otw.s

Even the not-present-detection seems to work somehow (!?). Ahh, that may be
because the optional symbols are actually resolved to __missing_function_ by
*rld* not ld.
But the original problem with libpthread remains:
[EMAIL PROTECTED] ~]$ cat t.c
int main(void) {
}
[EMAIL PROTECTED] ~]$ gcc -o t.o -c t.c
[EMAIL PROTECTED] ~]$ gcc -o t t.o -lpthread
/usr/lib/../lib64/libpthread.so: undefined reference to `_mpi_sgi_init'
collect2: ld returned 1 exit status
The actual ld call is as follows:
/usr/local/bin/ld -v -call_shared -init __gcc_init -fini __gcc_fini -melf64bmip
-o t /usr/lib64/mips3/crt1.o
/usr/local/gcc-4.0.1/lib/gcc/mips-sgi-irix6.5/4.0.1/64/irix-crti.o
/usr/local/gcc-4.0.1/lib/gcc/mips-sgi-irix6.5/4.0.1/64/crtbegin.o

-L/usr/local/gcc-4.0.1/lib/gcc/mips-sgi-irix6.5/4.0.1/../../.. -L/lib/../lib64
-L/usr/lib/../lib64 t.o -lpthread -lgcc -L/usr/lib64/mips3 -L/usr/lib64 -lc
-lgcc /usr/local/gcc-4.0.1/lib/gcc/mips-sgi-irix6.5/4.0.1/64/crtend.o
/usr/local/gcc-4.0.1/lib/gcc/mips-sgi-irix6.5/4.0.1/64/irix-crtn.o
/usr/lib64/mips3/crtn.o
Is there a difference in treatment of object and *shared* object symbols?
