[fpc-pascal] Using other fpc installation
For debugging reasons I have installed fpc 2.6.4 on Debian so I can compile some old SVN revisions, number 32959 for example. I want to use the fp editor to run the test, but it seems as the "systemic" 2.6.4 is being used for compiling instead of the SVN version. The bug doesn't show up in 2.6.4, only in some 2.7.1 revisions and later. How can I make sure the SVN version is used and not the systems 2.6.4? The following paths was added to fp editor in Options->Units: /home/roger/fpc/fpc_svn/lib/fpc/2.7.1/unitsx86_64-linux /home/roger/fpc/fpc_svn/lib/fpc/2.7.1/unitsx86_64-linux/* /home/roger/fpc/fpc_svn/lib/fpc/2.7.1/unitsx86_64-linux/rtl Also, both the directories of fpc and ppcx64 was added to the path from commandline: PATH=home/roger/fpc/fpc_svn/bin:/home/roger/fpc/fpc_svn/compiler:/usr/local/bin:/usr/bin:/bin export PATH=home/roger/fpc/fpc_svn/bin:/home/roger/fpc/fpc_svn/compiler:/usr/local/bin:/usr/bin:/bin Despite the path, if I run "which fpc" from commandline I get "usr/bin/fpc" anyway. How is that possible when that fpc is not in the path? ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

I meant to say that system fpc is put AFTER the SVN fpc in the path.

Re: [fpc-pascal] Using other fpc installation
Ah, so FP has no versions other than the official releases then? (2.6.0, 2.6.2, 2.6.4 and so on) Why doesn't FP use the same compiler revision as the SVN sources it comes with? Because the fp executable is compiled at the same time as fpc? Alright then, I'll try instead: fpc test.pas Btw, why have fpc and also ppcx64? Does fpc call ppcx64?

Then you use a 2.6.4 FP. FP does not call the compiler, it has an own version of it internally. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] Using other fpc installation
You're right, now I fixed that and "which fpc" reports the SVN version!

Due to the missing slash at the beginning of the PATH value? ;-) Obviously, that only answers the reason of the 'which fpc' command, whereas the compiler version used when compiling from the IDE has already been answered by Marco Tomas ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

It uses the sources from which it has been compiled (the same way fpc does too). Fp is a separate make target. It may be part of a snapshot, and it may be compiled from SVN sources by you as well (it has some additional prerequisites if you want to have the debugger integrated, and it requires some additional FPC packages compiled first, but nothing special apart from that). Alright then, I'll try instead: fpc test.pas Btw, why have fpc and also ppcx64? Does fpc call ppcx64? Yes - or another compiler binary if (cross-)compiling for a different CPU/platform (e.g. ppc386, ppcarm, ppcjvm, etc.).

Re: [fpc-pascal] Using other fpc installation
Alright, its compiling! It was wrong path in fpc.cfg. The DEB installation creates a directory structure under the fpc directory that matches this: /lib/fpc/3.1.1/units/$fpctarget Thanks again!

The results may be sorted also by language name and so all C++ results comes in before Pascal even if runtime is the same. Your program was as fast as No1 but anyway not visible among top ten.
