Linker error on HP-UX with OpenMP

[Josh Hykes]

Hello,

I posted this to the GNU Fortran Google Groups forum, but someone there 
suggested I post here instead.

I am trying to use gfortran on our HP-UX B.11.31 ia64 machine. After 
several false starts, I was able to build gcc-4.7.4 using HP's aCC 
compiler (I had to disable java).

Our code compiles with gfortran and runs successfully on the HP without 
OpenMP. (It compiles and runs okay with OpenMP on a variety of other 
platforms and compilers, including gfortran on linux.)

When I enable OpenMP with -fopenmp, the compilation fails in the linker 
stage with a series of errors like the following:

ld: The value 0xd01bf8 does not fit when applying the relocation TPREL22 
or DTPREL22 for symbol "ainf.2311" at offset 0x14cf1 in section index 1 
of file gendpx.o
ld: The value 0xd01bf8 does not fit when applying the relocation TPREL22 
or DTPREL22 for symbol "ainf.2311" at offset 0x14da0 in section index 1 
of file gendpx.o

The array ainf is a save'd automatic array that is declared 
threadprivate. There is no GNU linker on HP-UX, so this is using the HP 
linker.

I am compiling with the following options:

-mlp64 -O2 -fconvert=big-endian -fbacktrace 
-ffpe-trap=invalid,zero,overflow -fPIC -fopenmp

I have experimented with a variety of gfortran and linker options, but 
none of them have allowed me to fix the above relocation error. Does 
anyone have any experience with this error message, or any suggestions 
that I could try?
