i am to compile a software from source code. and encounter this error:

under the source code folder:
$./confiugre
checking for vendor f77 to be used instead of g77...
checking for f77... f77
checking for Fortran 77 compiler default output... configure: error: Fortran 77 compiler cannot create executables

thanx

Hi,

you can download g77 fortran compiler
instead of using f77 it will be
available on gnu site.

Probably you are running ./configure in a directory where you don't have write permission.

Good luck.

There is a gnu compiler package which will fix this. It will require you install the gnu-binutils as well so that you have an assembler, linker, etc...
While you download this, I would recommend you install gnu-make as well. These packages are available from "http://hpux.cs.utah.edu/hppd/hpux/alpha.html"

If your not comfortable with gnu software, HP sells a fortran compiler! It will come with a better make program as well as de-bug tools.
contact your HP sales rep for info

Hi

Your error suggests to me that the Directory
pointed to by pt/fortran/lib does not exist
(Relative to uour local directory.)
and I see in your error log that a setup shell was not found.
./configure[946]: conftest.sh: not found.

Probably a bad Path setting caused by the script not running..

"Permission denied" faults can happen if ld is writing to a directory where the user doesn't have write permission , either when writing
the working files in /var/tmp or the output libxxxx.sl file into the directory.

Another possiblity is if a libxxxx.sl file already exists, but is owned by another user and cannot be overwritten by ld.

It's found an f77 in your path, and is testing its capabilities. However, it's using command line options that the compiler does not support.

I'd just edit configure to drop the test with "--version" as an argument, and in the test where it tries to compile a file, drop the "-L/opt/fortran/lib" since it will link against the appropriate libraries automatically.
