Hello,
I see that most of the ELF on my system, contain a signature like so:
ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked
(uses shared libs), for GNU/Linux 2.6.32,
BuildID[sha1]=0x39645af26ea483eaae81df45bf34701580506115, stripped
There are two very interesting signatu

Hello all,
I'm compiling the program at the end of this message in x86 and x64 mode
using the following command lines:
ppc386 -MDelphi -CfSSE3 testFPU.dpr
ppcrossx64 -MDelphi -CfSSE3 testFPU.dpr
while I get an exe file and no error in x64 mode, I get the following
error message with ppc386:
Is it possible to cross-compile a Linux/x86_64 target on a Linux/i386
host? AFAICT it should be possible and I've almost got it working (using
Debian's gcc-4.4-multilib for start-up code) but the linker looks for
x86_64 libraries that aren't available on a i386 system.
I'm guessing that libraries

-XR is for pointing the compiler/linker to
Excellent, thanks Jonas.

If your x86-64 target is Win64, using -CfSSE2/-CfSSE3 w

Bugger, why does this keep happening to me???
Anyway, this time it is at the end.

I cannot reproduce the problem with 2.6.0/2.7.1 on Mac OS X/i386, nor with
2.7.1 on Linux/i386. I even don't see any comis* instructions in the code, the
comparison is
This is a pure fpc project, no LCL. If I have understood it correctly
then I have to call the CallAction() method for every connection I
have created but this seems to totally contradict what it claims to be
able to do: namely using some sophisticated event-mechanism that can
watch multiple handles

Hello all,
I want to find a way to write a streaming mechanic for Generic data
structures. For simplicity let's assume that I want to write a class
or function to stream TFPGList (I do not use them, but my set of
generic classes is written in a similar manner). However, due to FPC's
restricted gen

There is an error, but only adresses are shown.
How/ Where are the addresses shown?
Does your program has code of it's own, that dumps the stacktrace?
(normally added using with -gl)
Or do you run in a debugger (gdb?

The addresses were shown in the output window (console).

Can you create a generic that is based on a class that can stream
itself using rtti regardles of its structure ?
Something like
Type
TFundamentalClass = Class(TObject)
Public
Function GetProperty(Propertyname : String): Variant;
Procedure SetProperty(PropertyName : String; Value : Variant);
Proce
Closer, but not quite there yet...
To get this going I've (sshfs) mounted a 64 bit system on /mnt/engels
and then attempted to cross-compile on the 32 bit system with:
fpc -MDelphi -Scgi -CX -O3 -OoUNCERTAIN -OoREGVAR \
-Tlinux -Px86_64 -Xs -XX -va -l \
-dLCL -dLCLgtk2 -XR/mnt/engels
