make chugs along for a while and then abends with:

/opt/gold/bin/ld: cannot find -lc

collect2: error: ld returned 1 exit status

make[3]: *** [libgcc_s.so] Error 1

I have all the required dependencies at the correct levels. I googled the error but did not find anything useful

Ian, any suggestions?

That's not much information, but I would guess that you are on a 64-bit
x86_64 system and that this is happening when building the 32-bit
version of libgcc_s.so and that you don't have the 32-bit libc
installed. If that is the problem, then the fix would be to either
install the 32-bit development libraries or to use --disable-multilib
when you run configure.

I wasn't sure how much of the output to supply, but I am on a 64-bit x86_64 system. I used the commands from golang.org

mkdir objdir
cd objdir
../gccgo/configure --enable-languages=c,c++,go --with-ld=/opt/gold/bin/ld
make

After reading your reply:

make clean

../gccgo/configure --enable-languages=c,c++,go --with-ld=/opt/gold/bin/ld --disable-multilib

make

And I received the same error. Any other suggestions or is there more data that I could supply to help?

Do you have the file /usr/lib/libc.so? It normally comes from the
libc6-dev package (sudo apt-get install libc6-dev).

Yes, and apt-get reports "libc6-dev is already the newest version".

Does this work?

echo 'int main() { return 0; }' > foo.c
gcc -o foo foo.c -B /opt/gold/bin

If that works, tell us the output of this:

gcc -o foo foo.c -B /opt/gold/bin -Wl,-t

If that does not work, why can't gold find libc? How did you build
gold?

Hmmm, OK, that found libc.so via paths passed in from the gcc driver, so

Did you build gold yourself? How did you configure it?

What is the output of

That's not gold. I don't know what went wrong, because your configure
script should have built gold, but that is GNU ld.

When I built binutils following the gccgo instructions I ended up with
ld, ld.bfd and ld.gold in my bin directory ...
ld and ld.bfd were hard links to the same binary.

Hmmmm, looks like --enable-gold has changed so that it just installs
gold as ld.gold. You now need to use --enable-gold=default to get it to
be installed as ld. I will update the Go docs accordingly.

I have to admit that I am stumped by this. I cannot recall seeing any
similar report on a system where the file /usr/lib/libc.so exists.
There is probably a simple explanation but without being able to see
your system I don't know what it could be.

Can you send the contents of /usr/lib/libc.so? It should be a short
text file.

From a previous e-mail, the command which failed was:

Every time I've had to deal with this sort of ld nonsense, strace has
belped a lot. You might want to give it a go.

Argh, this is because Debian or Ubuntu has decided to change the
standard library locations and gcc has not caught up. Their version of
gcc presumably has the necessary patches.

I'm not entirely sure, but I suspect this is the patch:

http://patch-tracker.debian.org/patch/series/view/gcc-4.6/4.6.1-4/gcc-multiarch-trunk.diff

Or, as you say, add a symlink from the files in
/usr/lib/x86_64-linux-gnu to /usr/lib.

I tried the patch with -p1 since it affects several files in the directory, but it did not like that. So, I tried

patch < gcc-multiarch-trunk.diff

And it seemed to take.

make distclearn

../gccgo/configure --enable-languages=c,c++,go --with-ld=/opt/gold/bin/ld

make

This produced the same error referring to libc.so.

I then created a symlink.

cd /usr/lib/x86_64-linux-gnu

ln -s libc.so /usr/lib/libc.so.6

make distclean

../gccgo/configure --enable-languages=c,c++,go --with-ld=/opt/gold/bin/ld

make

This got me past the original error. However, there is now an error for libgcc_s.so

And I still get the error message above.

Is it looking for another libgcc_s.so?

It needs to be named /usr/lib/libc.so, not /usr/lib/libc.so.6. For
libc, the trailing .6 implies a shared library, a large binary file.
The plain libc.so is a small text file.

> Is it looking for another libgcc_s.so?

It's looking for libc.so. It's trying to build a new libgcc_s.so in
your working directory.

Another gcc patch that is said to fix this problem is
http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01649.html .

That's a dope slap for me, I overlooked the 6. However, I deleted the original symlink and then created

cd /usr/lib/x86_64-linux-gnu

ln -s libc.so /usr/lib/libc.so

And the result during make is:

/opt/gold/bin/ld: error: cannot open /usr/lib/../lib64/libc.so: Too many levels of symbolic links

collect2: error: ld returned 1 exit status

Yet:

sudo find / -name libc.so

[sudo] password for rhancock:

/usr/lib32/libc.so

/usr/lib/libc.so

/usr/lib/x86_64-linux-gnu/libc.so

Shows only these three, and /usr/lib/libc.so is a symlink to /usr/lib/x86_64-linux-gnu/libc.so

ls -la libc.so

lrwxrwxrwx 1 root root 7 2011-09-19 20:28 libc.so -> libc.so

If I remove this symbolic link, we are back to the original error that is stated earlier in the thread.

The error with the symlink states: /opt/gold/bin/ld: error: cannot open /usr/lib/../lib64/libc.so: Too many levels of symbolic links

but there is no lib64 under /usr/lib. Is it looking for another path other than /usr/lib/libc.so?

There is a standard multiarch package for Ubuntu 11.04 that was installed before I started any of this, but it obviously does not apply to gcc.

I tried the patch, but a lot of the hunks were rejected.

Note the /../. Is there is a /usr/lib64/libc.so?

I'm sorry for all this trouble. It is quite annoying that Debian chose
to make this unilateral change to library locations that had worked fine
for everybody for many years.

I appreciate your concern and all your help. Not much you can do when Debian takes its own path.

These are all the libc.so files on my system.

[sudo] password for rhancock:

/usr/lib32/libc.so

/usr/lib/libc.so

These are the lib64 directories.

Now the error involves Pthreads. Is it looking for a lib?

Most likely you need to set up a symlink for libpthread.so just as you
did for libc.so. libpthread.so should also be a small text file. You

Current gcc requires some additional libraries: mpc, mpfr, and gmp. It
looks like you have mpfr and gmp. You also need mpc. It may be in the
libmpc-dev package. Then you may need symlinks for those three
libraries, or you may not, I don't know. The linker didn't complain
about missing -lmpfr or -lgmp, so you may not need symlinks for those.
In any case, that should be all you need, I hope.

Eureka! The build completed and installed. I'm going to try to duplicate the process on another machine tomorrow, and I will post the results.

Last question, when specifying LD_LIBRARY_PATH does MACHINE a string like "amd64"? To what does VERSION refer?

Thanks for all your help. The support has been awesome.

The building of the compiler will be part of a presentation for the New York City GTUG at the end of the month. I hope I can provide the members with a set of instructions that will work for everyone.

Cool!

> To what does VERSION refer?

MACHINE is something like x86_64-unknown-linux-gnu. VERSION is the
version of gcc, something like 4.7.0.

To put it another way, MACHINE is what gcc (or gccgo) -v prints after
"Target:". VERSION is what it prints immediately after "version".

That worked.

One last caveat. You need an additional symlink to run a compiled program.

I think this error normally means that you need to install the flex
package, and then start over with a fresh directory.

I couldn't find this information with a Google search.

I had not installed flex before I ran it the first time. I did not know that I would need to start with a fresh directory. On to building gccgo.

This should close out the thread. I've built the compiler on another system with a fresh install of Ubunut 11.04 64-bit. Here are the steps.
