Building NCAR Graphics 5.2.1 on Solaris 10 x86u9 under Sun Studio 10 (2005)

Question

Hello,
I've got the following error when compiling ncar program with Sun
cc and f90 and /usr/ccs/bin/ld.
cc -ansi -O -I/usr/openwin/include -I/usr/include/X11 -DSYSV -
D_POSIX_SOURCE -D_XOPEN_SOURCE -DByteSwapped -Di386 -DNeedFuncProto -
c cl.c
cc: Warning: illegal option -nsi
cc: -a conflicts with -dy.
*** Error code 1
make: Fatal error: Command failed for target `cl.o'
After that i've changed the config/SolarisPC file and tried a build with gcc 3.4.3 and f90 but I got
ld fatal: library -lc not found.
I have an old box from 2001 which was under HCL of Solaris 8 x86.
The people at NCAR did not update their configuration files for Solaris 10 x86. The SolarisPC file is old and is using by default g77 as the fortran compiler. Could I mix gcc with f90 ? Which linker should I use in that case?
/usr/ccs/bin/ld or /usr/ucb/ld?

Please refer to the C Users Guide for details of cc command line options. All manuals for Sun Studio 12u1 are listed here:

There is no -ansi option in Sun/Oracle C, nor has there ever been. The compiler attempts to interpret it as -a followed by some other letters, which is why you get a complaint about -a. Remove the option.
Depending on what you expect from the -ansi option, either the default compiler behavior or the -Xc option should work. I suggest trying the default behavior (no -X option). Refer to the manual for details.
Always use the /usr/ccs/bin/ld linker, but you normally should not use the ld linker directly. If you mixing C and Fortran, use the f90 driver to do the linking; it knows what Fortran libraries need to be linked, depending on command line option. When linking a program using only C, use the cc driver to link. Some C command-line options require linking special system files; the cc and f90 drivers know the rules.
To mix Fortran with C, refer to the Fortran Users Guide. I recommend using the Studio C compiler when mixing code, not gcc. The requirements of gcc are not known to the f90 driver, but it does know the requirements of Studio C.
The schema for a mixed Fortran and C program is something like this:
cc -c f1.c f2.c <other options>
f90 -c f3.f90 f4.f90 <other options>
f90 -o myprog f1.o f2.0 f3.0 f4.0 <other options>
