RE: [libunwind] Libunwind would not make- HELP !!!!

[Earl]

Hello James

Thanks for your replay- further information regarding the Itanium platform
can be found below:

Operation System: Red Hat Linux Advance Server 2.1
Gcc version: gcc-2.96
Directory: /usr/bin/gcc


Gcc is working fine. It is g95 I am having problem with. G95 requires the
libunwind libraries - which I cannot make at present.

I downloaded g95 from: http://www.g95.org/ (open source FORTRAN 95 compiler
and runtime libraries.)


I have downloaded and installed the g95 binary below:
Linux IA64 Binary (64 bits) (2005-02-23 21:50)

I hope that I understand the thread of your answer: because gcc is used to
make the libunwind package - the path to gcc could be at fault.

Any further help would be appreciated.

Thanks Earl

You didn't mention the gcc version or the OS version.  Both of these is
more relevant than the linux kernel version.

You should not need the libunwind package in order to use gcc.  Gcc
would not have linked against a non-existent library.  If it did, you
would have gotten an error message much earlier.

The likely problem here is that you installed gcc in a directory that
isn't in the standard dynamic linker search path, and thus the dynamic
linker could not find the installed libunwind.so library.  You either
need to set LD_LIBRARY_PATH to point to it, or modify /etc/ld.so.conf
and run ldconfig.  Setting LD_LIBRARY_PATH is simpler.

Building and installing the libunwind package is still useful for other
reasons though, so it does help to do it.

Looks like you have an old obsolete glibc version, which implies that
you have an old obsolete OS version too.  You should consider upgrading
the OS.
