Version 1.8.2 of PIL was tested with following compilers :
on Solaris 8 : Sunsoft cc C compiler version 5.0, 5.1, 6.x (aka Forte 6) Sunsoft CC C++ compiler version 5.0, 5.1, 6.x (aka Forte 6) Sunsoft f90 compiler version 5.0, 5.1, 6.x (aka Forte 6) on Linux kernel version 2.2/2.4 : gcc/g++ C/C++ compiler version 2.7.*, 2.8.*, 2.95.2, 3.0.* Fujitsu Fortran 95 Express Version 1.0 (now Lahey ver 5+)
PIL library may be compilable with other compilers, however the PIL development team have access to only those aforementioned. Not all combinations of C/C++ and F90 compilers were tested.
Active development and debugging is done on Solaris with some work also on Linux.
Besides compilers, one needs the following system utilities :
gnu make (ver. 3.79.1) (Sun's /usr/ccs/bin/make does _NOT_ work) gzip tar (or gtar but renamed to tar)
