Hi there, I checked out the latest code from the repository, and wanna use the gold plugin, but I got the following: libLLVMgold.so: could not load plugin library Do you know why this is happening? Also I noticed the name of the library is changed to LLVMgold.so, and I just renamed it to libLLVMgold.so when I copied it. Is this the right thing to do? Thanks, Guoliang

...;llvm-gcc4.2-2.7-x86_64-linux" and I built Spec2006 with it. It is great and except for one benchmark the rest work fine. I want to build them with LTO now. I followed the directions in " http://llvm.org/docs/GoldPlugin.html" and built ar, nm-new, and ld-new in binutils. I also built libLLVMgold.so. I get the following error: llvm-gcc: -use-gold-plugin, but libLLVMgold.so not found. The command I used with the example in "http://llvm.org/docs/GoldPlugin.html" is: /home/reza/llvm-gcc4.2-2.7-x86_64-linux/bin/llvm-gcc -use-gold-plugin a.a b.o -o main I put libLLVMgold.so to /usr...

...h the document of that, After I built the binutils and LLVM with plugin enabling,and I also replace ld with ld-new which supports plugin,I tried to compile a hello world program by this: llvm-gcc -use-gold-plugin a.a b.o -o hello which is similar with the example in the document,it tells me that libLLVMgold.so can not be found ,but I truly put it in the directory which is the same as the cc1's. What's the problem with my libLLVMgold.so's position? Thanks! Nan

Yes,but ubuntu's directory structure is not exactly the same as the classic linux distribute, I put libLLVMgold.so in /usr/lib/gcc/i486-linux-gnu/4.2.4 where cc1 is also in. Strange situation,is it a bug for llvm-gcc???? 在 2009-09-18五的 12:58 +0300，Török Edwin写道： > On 2009-09-18 03:06, Nan Zhu wrote: > > OMG,that's just my situation... > > > > I can link with libLLVMgold.so manual...

OMG,that's just my situation... I can link with libLLVMgold.so manualy,but will fail in that by llvm-gcc. Debug llvm-gcc????? Any one installed the gold-plugin successfully can give some instruction? 2009/9/18 Rafael Espindola <espindola at google.com> > 2009/9/17 Nan Zhu <zhunansjtu at gmail.com>: > > Yes,it's indeedly the corr...

Try this: $ llvm-gcc -### -x c /dev/null Then look for a line containing cc1, something similar to this one: "/home/edwin/llvm-git/ins...

Try to link with llvm-gcc without the -use-gold-plugin option and with -v (it will fail as expected). Copy the collect2 line and add the -plugin line. If that does work, the only think I can think of is to run llvm-gcc in gdb and set a breakpoint on the error message. Cheers, -- Rafael...

Could be. Are you comfortable using gdb? Last time I looked it was working for me. Cheers, -- Rafael Avila de Espindola

...i, I fixed error by using different version of ld with LLVM 2.7. I used ld.gold that comes with Ubuntu 10.04.

The copy in that directory can have any name you like. BFD will try all. Note that that is the copy that nm and ar will use.
