cannot find -lc

cannot find -lc

[mahmoodn]

I got an error regarding the "ld". The error is:
...
/opt/cell/toolchain/bin/ppu-ld: cannot find -lc
collect2: ld returned 1 exit status
make: *** [test1] Error 1

I have found that it may be related to glibc, so I query the packages with
rpm and the results is:
[mahmood@Saturn minipthreads]$rpm -qa '*glibc*'
glibc-headers-2.8-3.i386
glibc-common-2.8-3.i386
glibc-2.8-3.i686
glibc-devel-2.8-3.i386

So I think I have everything needed. What is the problem then?:working:

The linker states it is not able to find the library libc.

Regarding the path where the linker "ppu-ld" is installed, I assume you
are cross-compiling for a Cell-Processor? If that is the case, you need
also the libc-Library compiled for that processor, and:

These are the versions of glibc for your actual system, on which you are
compiling - these libraries won't work on a Cell-Processor (I think...).

Maybe you should ask on a mailing-list of the project which created this
toolchain for crosscompiling for Cell-Processors? (www.free60.org ???)

I have these:
[mahmood@Saturn minipthreads]$rpm -qa '*libc*'
glibc-headers-2.8-3.i386
libcurl-devel-7.18.1-1.fc9.i386
glibc-common-2.8-3.i386
libcap-devel-2.06-4.fc9.i386
glibc-2.8-3.i686
libcap-2.06-4.fc9.i386
libcurl-7.18.1-1.fc9.i386
libcdio-0.79-3.fc9.i386
libconfig-1.2.1-2.fc9.i386
libcroco-0.6.1-5.fc9.i386
glibc-devel-2.8-3.i386

How about that? Are they correct?

Thanks, I will visit that.

Absolutely NOT !

It looks like that the PPU-toolchain requires TWO glibcs for PPU, 32-bit 
and 64-bit  :

[root@Dell lib]# file libc-2.6.so
libc-2.6.so: ELF 32-bit MSB shared object, PowerPC or cisco 4500, 
version 1 (SYSV), for GNU/Linux 2.6.9, not stripped
[root@Dell lib]# cd ../lib64
[root@Dell lib64]# file libc-2.6.so
libc-2.6.so: ELF 64-bit MSB shared object, 64-bit PowerPC or cisco 7500, 
version 1 (SYSV), for GNU/Linux 2.6.9, not stripped

One is expected to find things like "GCC for PPU" and "glibc for PPU" 
with very simple
net searches...  It took me only a few seconds to find the PPU 
crosstoolchain for a x86
host and the host-independent (but target dependent) glibc or "sysroot" 
stuff.
