/usr/lib/libc.a(iofclose.o):(.eh_frame+0x166): undefined reference to `__gcc_personality_v0'

Hi everyone,

I'm trying to compile a f90 program in 32bits with ifort v8.1 (Intel Fortran Compiler for 32-bit applications, Version 8.1 Build 20051007Z Package ID: l_fc_pc_8.1.031) on a x86-64 system (redhat 4.1.2-44).

I link statically with the libc using the following options:

LIBRI = $(MY_LIBS) -Xlinker -melf_i386 -static -Vaxlib, where MY_LIBS is the set of in-house libraries I'm linking with.

On of my library contains a routine written in C. I have compiled this routine using gcc (x86-64, version 3.4.6-4). The object is then archived with other F90-written modules to build a static library.

Then, at the link when buidling my final executable, I get the following error:

/usr/lib/libc.a(iofclose.o): In function `fclose':

GNU ld version 2.17.50.0.6-9.cgvel5 20061020
Supported emulations:
elf_x86_64
elf_i386
i386linux

I'm used to compile this program on another OS: RH 3.4 with gcc version 3.4.5 20051201 (Red Hat 3.4.5-2) and Ifort 8.1 and the build works fine.

I reckon that I should include some more option in my link. Any ideas?

Thanks very much in advance,

Ingrid

I don't think ifort 8.1 could work reliably with gcc 4.1, nor could .o files built with gcc-3 work reliably with gcc 4.1. Did you try rebuilding the gcc .o files, using gcc -m32?

Within limits, it is reasonable to build on the oldest of the systems you intend to run on, but there comes a time to upgrade. In any case, you need a consistent set of tools on the build system. For running on x86_64, it's usually advantageous to use the ifort intel64 and the default 64-bit gcc.

Even binutils 2.17.5, which is supported in some current linux versions, is old enough (over 3 years, according to your post) to have some difficulties with current releases of gcc and ifort, but this may not be a factor if you don't use any components less than 3 years old.

Hi Ingrid,

I came across this recently and was able to resolve the reference to __gcc_personality_v0 but adding -lstdc++ to the ifort command that linked the final executable.

An unresolved __gxx_personality reference clearly would indicate the need to link libstdc++. I agree with Steve this one is analogous in that it indicates a problem with gcc library vs. object compatibility.

Thanks very Tim and Steve for your inputs. I moved on by using intel 9.1 which corresponds to our current compilation level. As I still have to support older versions of my program, I'll still keep an eye on this and post something as soon as I found a workaround. Thanks again,

Regards,

Ingrid
