Hello Frank,

FH> Sorry, where's the output? I don't see any messages from the FH> compilers there, neither the mentioned "new style" message. (Please

Yes , that's true. The message about "new style" appeared when I built my main project. It is big and fat and I tried to create simple and little one just for testing. Message about new style does not appear when the test project is being built. Anyway there is something odd here since it doesn't gets built.

Hello Frank, hello List!

FH> "OK := False" in function ReadBufferAndIncludes, but it should echo FH> the message before ("WriteLn (StdErr, s);"), but again, no such FH> message above), or a shell command failed (but the last command

Thank you for your prompting, I hope I've found something.

First of all, yes, gp really exits with not Ok in function ReadBufferAndIncludes. Condition "if (Pos (': ', s) <> 0)" works and gp quits. It really prints the string confused which looks like "TOTAL : 0.00 0.00 0.00". This string is the output of "ppc-linux-gpc .... -E -H test.c" command. I think that ppc-linux-gpc just prints the summary of execution time and gp erroneously take it for error message (or something like this). It all worked for x86 target because gcc was called for *.c files processing instead of gpc as for ppc-linux-target and gcc doesn't print summary messages containing ": ".

I think that the problem is that I called gp with "PC=ppc-linux-gpc" parameter for ppc target. It worked for x86 because gp used gcc instead of gpc for c files processing. Gp doesn't work for x86 as well if I call it with "gp testpas.pas" command instead of "gp testpas.pas".

What is the best way to correct the situation?

Thank you for your help, best regards, Igor Marnat mailto:marny@rambler.ru

Hello Waldek, Frank and List!

WH> you should see something like: WH> ....../cc1 -E -quiet ....

Well, what is the decision? Is it bug in gpc, in gp, or am I doing something wrong?

1) If _unmodified_ gpc gives your result (and gcc does not!) I would consider it a gpc bug, however ATM it looks more like local modification (maybe a wrapper script?). Namely, the `-quiet' option is generated from `specs' file and is there. The part which reads (interprets) specs file is common to all platforms and is identical to code in gcc. BTW, I have build gpc targetting ppc-linux and I do not see timing reports.

2) Only Frank can tell if gp is supposed to cope with timing reports. When using unodified gpc one can give `-Q' option which turns time reports on -- Frank should decide if gp is compatible with this option.

Thank you for the prompting about specs file, I managed to investigate the problem a bit further. Hope it will help to find out the actual reason of the problem.

First I rebuilt and reinstalled gcc 4.0.3 and gpc 20060325 from downloaded sources to be sure there are no local changes of mine. Then I tried to find the -quiet option in 'specs' file of gcc but found that there is no 'specs' file in the place where it used to be. Having investigated gcc mailing lists I found that in GCC 4 they do not install specs file at all any longer but use built-in specs instead.

Then I found 'specs' file in gcc 4.0.3 build directory and copied it into its proper place manually. After that all works fine (gpc began to add -quiet option when call cc1).

To find out what exactly is going wrong, I removed specs file once again and saved the output of commands gcc -dumpsspecs and gpc -dumpspecs. Then I returned specs file to its place, regenerated the output of -dumpspecs and compared it with the output I got before (without 'specs' file). The output of gpc and gcc that uses build-in specs and the output of gcc and gpc with specs from file are the same.

Then I tried to run the following command with no file 'specs':

[igor@marnat2 4.0.3]$ /usr/bin/gpc -v -E -H /home/igor/tmp/test/test.c Using built-in specs.

<snipped> /usr/libexec/gcc/i686-pc-linux-gnu/4.0.3/cc1 -E -v -H /home/igor/tmp/test/test.c -mtune=pentiumpro <snipped> Execution times (seconds) TOTAL : 0.00 0.00 0.01

and with file specs in place:

[igor@marnat2 test]$ /usr/bin/gpc -v -E -H /home/igor/tmp/test/test.c Reading specs from /usr/lib/gcc/i686-pc-linux-gnu/4.0.3/specs

<snipped> /usr/libexec/gcc/i686-pc-linux-gnu/4.0.3/cc1 -E -quiet -v -H /home/igor/tmp/test/test.c -mtune=pentiumpro ignoring nonexistent directory "/usr/lib/gcc/i686-pc-linux-gnu/4.0.3/../../../../i686-pc-linux-gnu/include" <snipped>

As you can see the only difference is that in the second case cc1 is called with -quiet option and therefore it doesn't produce statistics output.

I have also installed in my system gpc of 20050217 version, based on gcc-3.4.3. When I removed its 'specs' file, it also began to omit '-quiet' option in an example shown above and refused to compile c files.

So the questions are

1. Since the built-in specs and specs from 'specs'

file are the same (as one can imagine comparing -dumpspecs output), why does gpc omit '-quiet' flag when it calls cc1?

2. What should I do in

order to go further with subject? I found the way to get it work for me (by restoring 'specs' file) but I'd like to be totally clear on this point.

I can now reproduce the problem. ATM (for about two weeks) I am away from home -- I will investigate it further when I am back home.
