Re: Performance of ld on GFS (Global File System)

Hi Ian,

I downloaded and compiled the latest snapshot of binutils:

GNU gold (GNU Binutils 2.19.50.20080929) 1.7

However, linking unfortunately failed, because the (Fortran) program
I work on needs OpenMPI which uses COMMON blocks:

./gold: lib/libbasic.a(mo_mpi.o): multiple definition of mpi_fortran_in_place_
./gold: lib/librttov7.a(RTTOV7_MPI.o): previous definition here
[...more similar messages deleted...]
./gold: mpi_fortran_in_place_: unsupported symbol section 0xff02
[...more similar messages deleted...]

At least these messages were emitted quickly... ;-)

Are there any chances that COMMON blocks will be supported?

Cheers,
Harald
