Hello FPC-Pascal users discussions!

Compilation shows me next ugly error messages during building lazarus with our components.

How can I turn on move verbose outputs to see more about the problem.

The strangest is, the same source code is buildable into Lazarus/Linux without any problem, but Linux runs on i386 and MacOS on PPC. I guess it is problem with compiler.

Thanks.

Start lazarus in gdb, reproduce the problem and create a backtrace.

If this is a compiler bug, try compiling the compiler with -gl to show line number information about the compiler crash. Usually this doesn't help me much tough, because I cannot fix the compiler. In such cases, I try to create a bug report with a small example that shows the crash.

Maybe compiling lazarus with -vl shows where the compilation process halts.

The Lineinfo unit does not work currently under Mac OS X. gdb works.

The lineinfo unit does work under Mac OS X (but only for stabs currently). Depending on the used system version, it may also only work if you start the program with the full path, because paramstr(0) is not guaranteed to contain the full path to the binary (as for why, see http://lists.apple.com/archives/darwin-kernel/2004/Jul/ msg00058.html ; and note that those arguments hold equally well for any *nix, so in general it's a bad idea to rely on paramstr(0) being a valid full path to some existing file).

Zitat von Jonas Maebe :

Ah.

This means: either lineinfo and a lot of linker warnings on each compile XOR no lineinfo and no warnings, right?

dwarf is the future, isn't it?
What is needed to get lineinfo working with dwarf?

If you don't use the patched linker, yes.

dwarf is the future, isn't it? What is needed to get lineinfo working with dwarf?

Support for
a) finding the original object files used to link the program (the paths are probably stored in the binary when you use dwarf) and reading the dwarf info from them
and/or
b) finding the dsym bundle and reading the dwarf info from that one (if you compiled with -Xg)

If you use

it should work fine.

But I don't see any debug information from freepascal's executable.

This is really strange, because our package is compilable alone without problem.

This line should only appear, if the Exception is an EOutputFilterError, not on EAccessViolation. Strange.
I will do some tests tonight on a Mac.

Indeed.

Zitat von Roland Turcan :

I think the AV happens somewhere in the finally part of ide/outputfilter.pas 375.
I added some verbosity in rev 15849.
Please update lazarus svn and compile IDE and lazbuild clean with -dVerboseOFExecute.
Then try again.

Can you reproduce the bug in a smaller package and send me the example?

Actually the package contains over 500 units, but when I/we find the reason then I will make some.

PS: I am going to holiday and I will not reply to any email (no computer, no Internet) until 4.8.

Thanks for everything you did for me.

Sorry. A misunderstanding.
You need to update lazarus svn and rebuild lazbuild itself, before trying to use lazbuild to build your package. Which means:

cd /usr/local/share/lazarus
svn up
make clean all lazbuilder
./lazbuild --build-ide=-va > all_output.txt

Note: Multiple parameters must be separated by space:

/usr/local/share/lazarus/lazbuild --build-ide="-va -dVerboseOFExecute"

[...]

Mattias

Hello Mattias,

MG> /usr/local/share/lazarus/lazbuild --build-ide="-va -dVerboseOFExecute"

I have done all things you wrote me, but the result of compilation didn't write any line written by WriteLn inside of IFDEFs. Maybe there could be a bug during parsing of -d parameter and IFDEF sections were not compiled into the code. Therefore I have commented IFDEFs out to get them into lazbuild and the result is the following:

MG>>> Sorry. A misunderstanding.
MG>>> You need to update lazarus svn and rebuild lazbuild itself, before MG>>> trying to use lazbuild to build your package. Which means:

MG>>> cd /usr/local/share/lazarus
MG>>> svn up
MG>>> make clean all lazbuilder
MG>>> ./lazbuild --build-ide=-va > all_output.txt

Zitat von Roland Turcan :

Or:
FPC does not automatically recompile units if a -d option is given. You must add a -B (build all) yourself or clean up before build. For example:

/usr/local/share/lazarus/lazbuild --build-ide="-dVerboseOFExecute -B"

ok. So, it is somewhere in EndBufferingOutput.
Can you add there some writelns and try again?

Mattias

Zitat von Roland Turcan :

Thanks. Maybe reading fProcess.ExitStatus does some strange things. I added a check in 15949 for the WaitOnExit, so that for a terminated process the ExitStatus is not read.

[...]

Mattias

Zitat von Roland Turcan :

Hmm. Maybe this means the compiler got an runtime error 217. I wonder what this means.

[...]

Mattias

-------- Original-Nachricht --------

That it stopped due to an unhandled exception (that is what RTE217 means).

Vinzent.

Hello All,

Does anybody have any idea, what I can do with this problem?

Thanks.

I never saw this problem.

Normally a process stopping with runtime error 217 gives:

TCompiler.WriteError Internal compiler error! (217) Internal compiler error! (217)

But Roland does not get this error message and the gdb backtraces do not help much. And for some reasons both lazarus and fpc have trouble. FPC gives 217 and TProcess can not handle it. So it is no normal 217.

Hello Mattias,

I have got some new facts about my problem. When I tried to execute lazbuild with

./lazbuild -B --build-ide="-va -dVerboseOFExecute"

I've got the executable. When I try to start it, then nothing is shown. When I try it over gdb then it writes that

in this point starts "Never ending story" and nothing is shown. Then I press Ctrl-C
