LAPACK/ScaLAPACK Development

Hi, I got a weird problem for you guys.
I followed the instruction and installed the clapack package sucessfully in my Red-hat Linux system. It passed all the testing.
I include the f2c.h and clapack.h
I linked blas_c.a lacpack_c.a and libF77.a in my makefile.
But when I call dsyev_(...) in my program, there are link errors, like:
../CLAPACK/lapack_c.a(dlamch.o)(.text+0x9d): In function `dlamch_':
: undefined reference to `pow_di'
../CLAPACK/lapack_c.a(dsteqr.o)(.text+0x823): In function `dsteqr_':
: undefined reference to `d_sign'
../CLAPACK/lapack_c.a(ilaenv.o)(.text+0x3b): In function `ilaenv_':
: undefined reference to `s_copy'
../CLAPACK/lapack_c.a(ilaenv.o)(.text+0x210): In function `ilaenv_':
: undefined reference to `s_cmp'
../CLAPACK/lapack_c.a(ilaenv.o)(.text+0x2b6): more undefined references to `s_cmp' follow
../CLAPACK/lapack_c.a(dlartg.o)(.text+0x63f): In function `dlartg_':
: undefined reference to `pow_di'
../CLAPACK/lapack_c.a(dlarfg.o)(.text+0x7b): In function `dlarfg_':
: undefined reference to `d_sign'
../CLAPACK/lapack_c.a(dlarfg.o)(.text+0x1d5): In function `dlarfg_':
: undefined reference to `d_sign'
and bla bla bla.................
I totally have no idea about this, and tried reinstall the whole clapack again, the problem still there. But for the win32 version clapack, under windows xp with visual studio , my code running O.K. No such error when calling dsyev_(...).
Any one has any tips to solve this?
Thanks

Hi Kukuttou

I'm not sure if this helps, but on my system (scientific linux 4.4), these symbols are defined by the f2c library /usr/lib/libg2c.a so -lg2c would allow them to be resolved.

Hope this helps.

Ian.

Hi,

I generaly noticed that you have to add the libraries in the correct order. There you use clapack, this would be

lapack_c.a blas_c.a libF77.a libI77.a

With those four libraries and in this order it should work properly
