Dear Sirs. Since we use FreeBSD as our plattform here I ran into many problems using f90 compilers. While Lahey's LF95 for Linux worked in FreeBSD 4.2 and up to 4.3-RC2, it has now several strange problems I con not figure out. VAST F90 is no option due the fact it does not support all F90 features. The main problem is that all compilers are for Linux and has to be run in Linux emulation. But this offers much more problems than expected - not served by FreeBSD, but by secondary libraries. We need the NCAR Graphics library as well as several NAG libraries. I read about a native FreeBSD NAG compiler, but the stupid policy of NAG offers this compiler only for a fee of about 30 British Pounds for the trial version - Linux version is free as many other versions for trial :-( I never successed in compiling NACRG libs on FreeBSD due sveral problems with FreeBSD 4.3-STABLE (some scientists seem to have compiled the libs prior in FBSD 4.2 successfuly). Instead, I use the Linux most recent Linux libs but they have several problems with the Lahey compiler (compiling with the VAST F90 is all right, but compiling code with Lahey F90 produces errors, LF95's linker does not find the NCARG libs and reports many errors). All the Linux tests were made in a chrooted Linux environment. One of the most important dilemmas is the following: Most scientific development is done with Linux and NAG libs. Therefore most of my professors 'cry' for LinSux but I'm not willing to give up the better plattform for only this small focus (a small focus, but a big effect!). My question is the following (I'm not a compiler expert): Imagine, I would like install a native NAG compiler (which is not the fastest one like Lahey/Fujitsu) for FreeBSD, and the appropriate NAG libraries. Then I have no NCARG libraries for FreeBSD due the fact that NCARG does not support FreeBSD. On the other hand, if I order all parts for Linux, I'm sure there will be problems with the emulation, at least the debugger (Lahey's LF95 debugger is not working properly under the emulation, PGI debugger also seems to have problems, it crashes many times I tried to use it). The alternative will be to support here a Linux server architecture for all purposes - but I don't want to face the NFS performance, the network speed and other 'goodies' of Linux. -- MfG O.
