Hi,

with latest fpc 2.1.1 I get:

cat test.pas
program test; begin writeln('test'); end.
ppc386 test
Free Pascal Compiler version 2.1.1 [2006/02/23] for i386 Copyright (c) 1993-2005 by Florian Klaempfl

kind regards,

Den Jean

Make sure you have updated all files from svn. The __stkptr is defined in the loader files named *ptr*.o

I have the same problem, but with libraries. dlopen() always fails to load them and dlerror() returns: "../test/libtest.so: undefined symbol: __stkptr"

I just updated to the latest svn.

Thanks,
Och

svn update gives: At revision 2674 still same __stkptr problem.

Fixed

Check with objdump if dllprt0.o exports the __stkptr.

Better change it to /usr/lib/fpc/$fpcversion/units/$fpctarget

I did
svn update fpc
now I did
rm -fr fpc
svn checkout http://svn.freepascal.org/svn/fpc/trunk fpc cd fpc
make PREFIX=/usr clean
make PREFIX=/usr all
make PREFIX=/usr install
ln -fs /usr/lib/fpc/2.1.1/ppc386 /usr/bin/

svn update gives:
At revision 2674

still same __stkptr problem.

As i have problems with fpc 2.0.2 I compile fpc with 2.0.0

The problems with 2.0.2 are that some calls to libqt4intf fail (exception div by zero) and not with 2.0.0
I still need to trim down a sample program to be able to report the bug, but is ok to compile 2.1.1 with 2.0.0 ?

BTW the dll fails for a call to this
void QPainter_drawLine3(QPainterH handle, int x1, int y1, int x2, int y2) {

	((QPainter *)handle)->drawLine(x1, y1, x2, y2);

}
if i printf the parameters within this dll, they are fine (no reference/value/byteswap problem but something else)

another call fails after a while, something extra on the stack ???

with fpc 2.0.0 everything works fine, even when the programs runs for a longer time.

kind regards,

Den Jean

objdump -t dllprt0.o | grep stkptr
00000000 g O .bss 00000004 __stkptr

so i checked further and i found that just doing
ln -fs /usr/lib/fpc/2.1.1/ppc386 /usr/bin/
is not enough to switch fpc versions,
because the fpc.cfg from fpc-2.0.0-2mdk.i586.rpm contained -Fu/usr/lib/fpc/2.0.0/units/$fpctarget
-Fu/usr/lib/fpc/2.0.0/units/$fpctarget/*
-Fu/usr/lib/fpc/2.0.0/units/$fpctarget/rtl

I removed these lines and all ok.
big apologies

But 2.1.1 gives me the same problems as with 2.0.2 The Qt4 binding does not work. They told
me that lazarus requires 2.0.2, so it is a problem that my binding does not work with 2.0.2

So I will upload a demo program that demonstrate the problem

kind regards,

We should change the installer so it adds this line to the generated config file.
