You can't do it using linux alone. You must install cross-target binutils. Specifically: the linker must create a linux binary instead of a Windows binary. Once you have those installed (there is a zip floating around somewhere) you must point the compiler to them with the -FD parameter.

[fpc-pascal] Win32 DLL problem / VST audio plugin
Hi everybody, I got a problem compiling a win32 DLLs with latest fpc/lazarus. The DLL is a VST-Plugin, using the Delphi template from http://www.tobybear.de exporting just one function "main", working perfectly under Delphi. The only thing I found on the net was: http://www.nl.freepascal.org/lists/fpc-pascal/2002-January/002663.html Three years old. And doesnt work. I checked (MS DLL dependency walker) the linked DLL (extremely big: 4,5 MB compared to same compiled under Delphi: 400kB) with correctly exported function "main" (only if *NOT* smart linkable -CX) and noticed a wrong Link checksum (compared to real checksum) No need to mention: the linked DLL doesnt work under any host... I think this got something to do with the right compiler switches for static/dynamic librarys... But no way... AND PLEASE: Dont tell me to use the original Delphi, I know there are free PE versions ... I finally want it to compile on a MAC, too! Please, if you got any suggestions... Thanks for your reply. And best regards. ./chrom ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] Version 1.9.6[??] on the Mac.
Pedro Lopez-Cabanillas wrote: You need to use FPC 1.9.4 or later; 1.9.6 should work, as Jonas pointed, because I'm using some features not available in older releases. Here's a really curious thing! I've been working to compile smf.pas. I've loaded fpc 1.9.6 on Windows XP and, indeed, it compiles perfectly - later I get errors finding Libc, but that's understandable as it isn't Unix, besides I really want it wo work on the Mac. So, I've loaded fpc 1.9.6 on my Mac (powerpc, Mac/OS 10.x.x - the latest). When I try to compile it, I get the same error about the byte array, using Xcode. So I tried it with a command line compile: ppcppc -Sd smf.pas I get the same problem! This was very peculiar, so I tried: ppcppc -iV 1.9.6 So I haven't loaded the wrong compiler by mistake. It looks very much as if the code for the 1.9.6 compiler on Windows/XP and Mac/OS is different - in fact it looks as if the Mac version is an earlier release. How could this have happened? Should I download the compiler and compile it from scratch, or is it likely that somebody will fix the problem? Could I have something else wrong? Have you actually managed to compile this on a Macintosh running the Panther OS? While on the subject, of compiling the compiler. I have a dual 64-bit CPU on my Mac. Would it be possible to compile the compiler to run in 64bit mode and be multi-threaded - and produce code that is 64bit and multi-threaded? I know that Tiger will provide full 64bit operation (at least that is promised), but, in theory, the compiler should be able to produce 64bit code now. If not, how long before this will be possible? Is it difficult to do? ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Skybuck,
thanks for the detailed guide. However, it was simpler than that...
with the help from the guys at #fpc, I got
ftp://ftp.freepascal.org/pub/fpc/contrib/cross/mingw/mingwcross.zip
Unzipped that to \cross, then got myself some linux libs
needed for the dynamic linker (libc.so.6 and friends) and finally
I'm able to cross-compile hello world
C:\pp\demo\text>fpc -Tlinux -FDc:\pp\cross\i686-linux -XPi686-linux-
-Xd -Xc -Fl c:\crosskylix\lib hello.pp
This is with dynamic linking of libc as pthreads is going to be used.
The resulting binary is a valid dynamic ELF file:
[EMAIL PROTECTED] /home/scamp# ldd hello
libc.so.6 => /lib/libc.so.6 (0x2aade000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x5000)
So far so good. Sadly it segfaults:
[EMAIL PROTECTED] /home/scamp# strace ./hello
execve("./hello", ["./hello"], [/* 26 vars */]) = 0
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
Static linked binarys work fine, though. Now I only have to find out
why everything dynamically linked crashes.

The addresses where the shared libs should be loaded, look very strange
usually it's 0x4000+ ?
