newbie question: nag90 and lf95

Hi,

I have nag90 library and lahey-fujitsu's lf95 compiler.
I'm trying to compile something in lf95 using
nag90 modules but its not working.

Do I have to use NAG's f95 compiler to be able to
use its libraries? I noticed that nag's modules
are readable while modules produced by lf95 are
unreadable. It seems inconsistent.

Thanks.

Yes. The format of the file generated by a module usually
is very specific to a compiler - it may be a straight binary
dump of its internal symbol tables, for instance. I don't
know of any two compilers that produce compatible module files.

It is true that if you create a library from your Fortran 90 code using the
NAG F90 compiler, the library will not be callable from another compiler.

I think the OP was asking about using the precompiled NAG Fortran math library
with Lahey Fortran. NAG sells its math library for numerous compiler/operating
system/hardware configurations, and whether the library is compatible with
LF depends on which version of the library he bought. He should consult the
documentation of the NAG library and/or consult his system administrator
or NAG technical support.
