This means, -O3 -O1 will not switch the compiler "back" to -O1, just stay at -O3, because at -O3 level, all -O1 optimizations are already enabled, there is nothing to enable. -O- however will disable all optimizations. So if you want to disable all previously enabled optimizations, you indeed need to go to the -O- -O1 route. So it is actually useful. (The above is quite easy to verify, see options.pas, line 2350 and below in the compiler sources.) Charlie Good to know. Now I am pretty sure that I copy that options from someone else, because with my knowledge I could not figure out that myself. Thank you Charlie.

My script have many years and I don't remember why I used this options or if I gathered them from someone else, but reviewing it now, it does not seems logical.

Re: [fpc-pascal] Just out of curiosity: Compiling FPC trunk and fpcmake
Hi,
Thank you very much to everyone for the quick answers.
If I specify the option PP=.../fpclazarus/fpc/lib/3.2.2/ppcx64 to the
command "make -j 9 clean all", the it works as expected. Probably until
now, it worked just by pure lucky.
But just to make sure my script to build FPC is safer, is this is ok?
make -j 9 clean PP=.../fpclazarus/fpc/lib/3.2.2/ppcx64
make -j 9 all install FPMAKEOPT="-T 9"
INSTALL_PREFIX=.../fpclazarus/fpc/cmp/3.3.1 OPT="-O- -O1 -gl"
PP=.../fpclazarus/fpc/lib/3.2.2/ppcx64
It works, but I want to make sure that this is the right way to build FPC.
P.D. :Thank you very much to the FPC team for this great project.
Best Regards.

I have been a few months without compiling FPC trunk, but when I tried it
today, I got the next message after calling "make -j 9 clean all"
make: -iVSPTPSOTO: Command not found
This indicates that the PP variable is not valid ?
I run make clean all almost daily, I have not seen what you report here.
I can reproduce this, or something very similar for the clean/distclean
targets, if I have no FPC installed on my machine, but I specify PP= as a
Makefile argument to a "bootstrap" compiler binary, and I use OS_TARGET=
as well, for crosscompiling.
For example, if I try this on Linux/x86_64:
make clean OS_TARGET=aros PP=/path/to/bootstrap/ppcx86-3.2.2
I get a lot of messages like:
ake -C compiler distclean
make[1]: Entering directory '/home/charlie/Develop/fpc/source/compiler'
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
/bin/rm -f ppcrossx64 ppc ppc1 ppc2 ppc3 ./msg2inc pp1.wpo pp2.wpo
So there's definitely something fishy with the bootstrap/PP compiler use,
if the build box has no FPC installed otherwise. Which to my
understanding, it shouldn't be needed, if PP is specified?
Interestingly, if I don't specify OS_TARGET, the problem doesn't occur.
Note that for a real build ("all" or "crossall" target), the specified PP
compiler still gets used as expected.

[fpc-pascal] Just out of curiosity: Compiling FPC trunk and fpcmake

Stop. I just run fpcmake before call "make clean all" and "make -j 9 all install", and everything works as expected. My question is, until now I have never needed to call fpcmake before compiling trunk, it is a requirement now to execute fpcmake or there is something wrong in my side? My system is Xubuntu Linux x86_64. Thanks. Best Regards. -- Victor Campillo ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

[fpc-pascal] Question about compiling FPC trunk after revision 44849
Hi, For years I have been using the same script to compile FPC, in this script I use the next command: make -j 9 clean all install After the revision 44849 the use of the jobs option does not work anymore, it fails to compile, reviewing the changes in revision 44849 shows that was removed the option ".NOTPARALLEL" in the Makefile, and this option as far as I know leave without any effect specifying the option --jobs, so my using over the years of the option "-j 9" was actually useless. Probably I am doing something wrong, but to be sure, ¿it is supported to use the jobs option of make?
