Hi,
trying to build a fortran extension linked to lapack (f77), I faced a
problem that I reduced to the following example.
------------ testfile.f90 ------------
subroutine testfunc
integer,parameter :: n=2
integer :: iseed(4)
real(kind=8) :: x(n)
iseed = (/0,1,3,4/)
call DLARUV(iseed, n, x)
end subroutine testfunc
--------------------------------------
Then : f2py -c -m testmod -llapack -lblas
-L/home/raynaud/soft/lapack_gfortran/lib testfile.f90
It rises the following error (using gfortran) :
/usr/bin/ld:
/home/raynaud/soft/lapack_gfortran/lib/liblapack.a(dlaruv.o):
relocation R_X86_64_32S against `.data' can not be used when making a
shared object; recompile with -fPIC
/home/raynaud/soft/lapack_gfortran/lib/liblapack.a: could not read
symbols: Bad value
BLAS and LAPACK where compilated with gfortran and options '-fPIC -O3'.
I tried to use the DATA statement directly in a subroutine that I
converted to a python module, and it worked.
Any idea ?
Thanks.
