Hello,

Regarding this bug: http://bugs.freepascal.org/view.php?id=16983

Does anyone have any ideas about what I should be looking for to fix it?

I got stuck in the stack frame between #2 and #3:

0000002 0x00121d20 in JERROR_ERREXIT1$J_COMMON_PTR$J_MESSAGE_CODE$LONGWORD () 0000003 0x000fe9b0 in
FPREADJPEG_TFPREADERJPEG_$_INTERNALREAD$TSTREAM$TFPCUSTOMIMAGE_READPIXELS ()

Because there is no call to ErrExit in FPReadJPEG.pas

thanks,

In our previous episode, Felipe Monteiro de Carvalho said: [ Charset ISO-8859-1 unsupported, converting... ]

But there is:

 FError:=jpeg_std_error;
 FInfo.err := @FError;

Maybe something ancestor can call it?

Ok, so in order to solve this problem I guess I need a RTL with debug info, so in my Mac OS X I went for:

cd ~/Programas/fpctrunk/
make clean all install INSTALL_PREFIX=~/Programas/fpctrunk/install

Then set my Lazarus compiler path to
/Users/felipe/Programas/fpctrunk/install/lib/fpc/2.5.1/ppc386 which is a 2.5.1 compiler

But when I try to rebuild the LCL I get:

/Users/felipe/Programas/fpctrunk/install/lib/fpc/2.5.1/ppc386 -gl -Fu. -Funonwin32 -Fuforms -Fuwidgetset

Which makes no sense, because I just built the compiler, how can the PPU version already be wrong?

Any ideas?

thanks,

Look at the compiler messags. it is not loading your freshly installed units, but the units in some other location:
/usr/local/lib/fpc/2.5.1/units/i386-darwin/rtl/

Your compiler path is wrong.

Michael.

I see, I had supposed that make install had put those files there in addition to my install prefix, but they are probably leftovers from a snapshot I installed a long time ago or something. Very bad that Apple doesn't build uninstallers ... what a shame.

But now I got it working, but it was all to not much gain, JPEG loading works perfectly in 2.5.1 ...

Now I wanted to check if it works with fixes2_2, but I can't compile it:

make clean all install INSTALL_PREFIX=~/Programas/fpcfixes2_2/install

/bin/rm -f fpcmade.i386-darwin Package.fpc ppas.sh script.res link.res /bin/rm -f *.s *_ppas.sh

Any ideas?

I'm pretty sure the starting compiler is not 2.4.0, since you previously said that you performed a global install of FPC 2.5.1. What does "fpc -iV" return?

My global compiler is 2.4.0, those global paths were probably a very old snapshot install. I also changed my fpc.cfg for 2.5.1 to test JPEG, but now I changed it back again to the old paths to build fixes2_2

MacBook-de-Felipe-Monteiro-de-Carvalho:fpcfixes2_2 felipe$ fpc -iV 2.4.0

Ah ... I was trying to build fixes2_2 ... that' FPC 2.2 !!! o.O

I just blindly following the link here:

http://www.freepascal.org/develop.var

Ok, great, thanks all for the help, whatever it was, it's already fixed in FPC 2.4.3, and probably in the upcoming 2.4.2 too

Now going to fixing the develop.var page, how can I download the fpchtml? I tryed the following:

MacBook-de-Felipe-Monteiro-de-Carvalho:Programas felipe$ svn checkout http://svn.freepascal.org/svn/fpchtml fpchtml
svn: OPTIONS of 'http://svn.freepascal.org/svn/fpchtml': 200 OK (http://svn.freepascal.org)

But nothing was downloaded ...

You missed a slash:
