Hi,

I have a problem when I enabled gdb compilation on host side:

----

To fix the issue, I had to copy manually the libiberty.a file from pic/ 
directory to the host target directory:

----
cp output/build/host-gcc-final-4.7.4/build/libiberty/pic/libiberty.a 
output/host/usr/lib/libiberty.a
----

I use buildroot 2015.5 and I have a amd64 arch.

Maybe a patch in gcc package to copy libiberty.a from pic is needed for 
x86_64 arch like me. What do you think about that ?

Regards,
Anthony.

 This is where libiberty should be found...

 ... but instead, it is found in host/usr/lib.

 That's pretty bad, libiberty should not be installed in the host dir. I also
can't find any code that does that (nothing passes --enable-install-libiberty
except the target binutils).

 So can you trace back which step of the build installed libiberty in the host
dir? Perhaps share your defconfig?

 Arnout

----------------

The file libiberty.a seems to come from the gcc-final package but it 
doesn't have the same md5 hash. I think gcc doesn't make a simple copy 
but modify the installed ar archive ?

Near the end of the build of gcc-final, I can see this:

----------------

I can see in my build log there is binutils which can install the lib 
but the install command is surrounded with "if test	-n ""; then \" so 
nothing is done.

The openwrt guys did a patch in gcc/final package: 
https://dev.openwrt.org/changeset/42625

I use gcc 4.7.4.

I pasted my config and the build log here:

 Right, seems that gcc 4.7.4 installs it but later versions don't do that anymore.

 Simplest workaround is to remove libiberty.a from HOST_DIR after the build. I'm
not sure if it's still worth it to do this in buildroot itself.
