Fortran Freezes While Compiling
I am trying to compile two different codes distributed by NASA. It is written in fortran 77 and I am trying to compile it on Sun Solaris 10 . The first source distribution begines compiling fine. The library of functions develops appropriatly until it gets to one of the subroutines that it needs to compile. At that point, it just freezes. It does'nt return control to the command line, it just stops comiling and stays where it's at. Any ideas? The second set of code says that there is a "bad leaf",what is this? Thanks.

I am using the most recent fortran compiler released with Solaris Workshop. It is a fortran 95 compiler. (There might be a problem that the code I am compiling is written in fortran77). Anywho.
For program 1, I get the following: (includes some info before the error occurs)
NOTICE: Invoking /opt/SUNWspro/bin/f90 -f77 -c -fast -ftrap=%none -xtarget=generic //export/home/ins3d2.1b/src/ilusolF.f

iluini1:
compiler(iropt) error: leaf_lookup_expr: bad leaf (tag=0)
*** Error code 1
make: Fatal error: Command failed for target `//export/home/ins3d2.1b/lib/ins3d.dp.a(//export/home/ins3d2.1b/src/ilusol.o)'
Current working directory /export/home/ins3d2.1b/src
*** Error code 1
make: Fatal error: Command failed for target `sun_dp_lib'
The second code does this:
//export/home/ins2d2.2c/src/metricF.f:
metric:
metric2:
metric3:
timemet:
and then it just stops linking. It does not return control to the command line. It just sits there like that.
Thanks again.

What is the output when you type "f95 -V"?

That shouldn't cause any problems.

What happens if you compile without optimization?

Sometimes the optimizer takes a very long time to finish compiling a file. If you run prstat in another window while the compiler is sitting there, does it show "iropt" , "cg", "ir2hf" or "ube" consuming a lot of CPU time?

The output of f95 -V is:
# f95 -V
f95: Sun Fortran 95 8.2 2005/10/13
Usage: f95 [ options ] files. Use 'f95 -flags' for details
How do I compile without optimization? Sorry, I am very new to the non windows platforms.
Yes, it shows iropt consuming a lot of CPU time.

You can compile without optimization by removing the "-fast" flag from the compilation command. (Of course, the code will not run as fast when compiled without optimization. This is just a way to find the source of the problem. If it compiles correctly without optimization, then you can try using "-O1". If that works, then try "-O2", and so on.)
The "bad leaf" error message indicates an internal compiler error. So far as I know, this is not an error that has been reported before. Is there a way for us to get access to the source code?
