Has anyone tried to build a Free Pascal Windows crosscompiler on an Intel Mac ? Is this supported ?

First I built and mingw binutils and then I tried

[p17:~/fpc-win32/fpc] adriaan% make all OS_TARGET=win32 CROSSBINDIR=/usr/bin BINUTILSPREFIX=i686-ming32- INSTALL_PREFIX=/usr/local make compiler_cycle RELEASE=1

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

.....

Yes, you don't need a cross-compiler to cross-compile to different operating systems. With FPC 2.1.4+ you don't need binutils either to cross-compile to Win32.

Simply make the rtl:

cd /path/to/fpc/rtl/win32
make

Then simply compile your program:

fpc -Fu/path/to/fpc/rtl/units/i386-win32 -Twin32 myprogram.pas

Happy crosscompiling!

Ah, thanks for your reply.

Simply make the rtl: cd /path/to/fpc/rtl/win32 make

I did that and it works. However, it doesn't seem to copy any files to usr/local/lib/fpc/2.3.1/units/i386-win32/. I tried

When I copy some of the .o and .ppu files by hand to /usr/local/lib/fpc/2.3.1/units/i386-win32, crosscompiling hello.pas works.

Most of the win32 rtl is built by a build unit called buildrtl.pp in the directory rtl/win32. rtlconsts is listed in this unit and should have been compiled. Could you check wether the compiler does the actual compilation of rtlconsts? If yes, where did it place the rtlconsts.ppu?

Daniël

There was a /rtlconsts.ppu in objpas, which caused the problem. I think this was the result of my various experiments this morning. After checking out clean sources, "sudo make install worked" and also the crosscompiler.

Note that you can install Wine (I'm not sure though how the Darwin port hasprogressed) to do testing. With Wine you can do the full development without a Windows computer and you only need to do some final compatibility testing on Win32.

Daniël

Does wine run on intelmacs too? I didn't know that.

Well, I see articles like this http://tweakers.net/nieuws/44225 , so people are definately working on it.

Since we are on the topic, I've been using Parallels Desktop for Mac with a lot of success. It's pretty cheap, and you have 2 weeks to see if you want to buy it. They have some bugs when running Linux, but their Windows support is incredible. Windows seams to actually work better and faster then in my PC Notebook =) Really

One downside is having to buy a Windows license only for this, but this wasn't a problem for me as my University gives me free MS products througth the Microsoft Academic Alliance.

Yes, I am running Parallels Desktop for Mac for that purpose also. I tried CrossOver some time ago and weren't impressed. Maybe things have improved since.

This is how far I got with the crosscompiler:

But maybe this is something to ask on the Lazarus mailing list.

Can you try -vt to see if and in what directories the compiler tries to search windres?

It could very well be that the compiler searches for windres.exe, this would be a bug.

Daniël

Ah, yes, it was looking for "i386-win32-windres"

On my mac, /usr/bin/windres is actually a symbolic link to i686-pc-mingw32-windres, but after adding the i386-win32-windres symbolic link, lazarus cross-builds with success !
