Hi,
I was trying to use gold plugin to compile and run some of my passes on some
large softwares like mysql, apache etc. When I compile using llvm-gcc,
everything works fine. But, when I followed the instructions on
http://llvm.org/docs/GoldPlugin.html#build to use gold plugin, I got errors
like:
/home/vadve/ssahoo2/local/bin/ld: error: modules/standard/libstandard.a: no
archive symbol table (run ranlib)
/home/vadve/ssahoo2/local/bin/ld: error: modules/extra/libextra.a: no archive
symbol table (run ranlib)
/home/vadve/ssahoo2/local/bin/ld: error: main/libmain.a: no archive symbol table
(run ranlib)
....
I tried ranlib/llvm-ranlib, but it didn't work. Can someone help me, if I am
doing anything wrong here?
Thanks,
Swarup.

Hi,
I am giving more details about the commands which gave these errors below,
which may be helpful in figuring out the problem.

like:

>/home/vadve/ssahoo2/local/bin/ld: error: main/libmain.a: no archive symbol
table (run ranlib)
>....
I got these errors when build system was running the following command:
lvm-gcc -use-gold-plugin -DLINUX=2 -DUSE_HSREGEX -DUSE_EXPAT -I./lib/expat-lite
-DNO_DL_NEEDED -O4 `./apaci` -o httpd buildmark.o modules.o
modules/standard/libstandard.a modules/extra/libextra.a main/libmain.a
./os/unix/libos.a ap/libap.a regex/libregex.a lib/expat-lite/libexpat.a -lm
-lcrypt
When I replace llvm-gcc with the following ld -plugin command, I also get the
same errors:
ld -plugin ~/local/lib/libLLVMgold.so -o httpd buildmark.o modules.o
modules/standard/libstandard.a modules/extra/libextra.a main/libmain.a
./os/unix/libos.a ap/libap.a regex/libregex.a lib/expat-lite/libexpat.a -lm
-lcrypt

Can someone help me, if I am doing anything wrong here?You shouldn't need ranlib nor llvm-ranlib. I'm not entirely sure what's up with the .a files. It looks like ar has grown a --plugin options to match gold, whereas I seem to recall it used to just look in a fixed directory. Rafael, have you been following what binutils has done with plugins for ar, nm and friends? It looks like we might need to update llvm-gcc to pass the gold plugin flag to ar and nm.

But, llvm-gcc doesn't automatically pass this option to ar.> >Nick > >> >> Thanks, >> Swarup. >> >> ************************************* >> Swarup Kumar Sahoo >> Thomas M.

Swarup, can you check that you can run nm in a file with LLVM IL and it displays the symbols?> Nick >Cheers, -- Rafael Ávila de Espíndola
