Targetting Linux from Windows...?

[KillerCode]

ive looked alot for this one, but most of what i found was compiling lazarus itself to work on a linux box..

i was wondering if its possible to compile Linux executables while im still on windows? so lazarus produces windows and linux executables while im still on windows.

thanks...

It is possible, but it is in general only worthwhile for people deep into crosscompiling. It also needs libraries copied from the target Linux installation to the Windows machine.

Since you have to install Linux either way, one might as well compile under Linux.

The build faq has a few pointers and background info about crosscompiling. If you persist, read it a few times back to back.

The other way around is much simpler since you don't need any kind of difficult setup. Just recompile RTL, FCL, LCL (+all required 3rd party packages / libraries) for Win and you can compile for it from Lin.

too hard for me to move totally to linux, what about producting 64bit windows executables from 32bit windows?
is it possible? or i need 64bit machine for that too?

[Laksen]

That is possible

how can i do it?

you can use virtualization,
download virtualbox from http://www.virtualbox.org/ and install any linux you want to the virtualbox, then install lazarus and compile.

In this case, it's as easy as cross compiling from lin32 to win32 I described above. This is because for win32/64, FPC has its own internal linker and Windows PE (.exe) doesn't need the presence of required dlls (it would be searched at runtime by the OS).

what about from win32 to win64, how can i do that? any tutorial?

Please read the foreword as well, and add INSTALL_PREFIX to the make command specifying base fpc folder. e.g.:

Code: [Select]

make OS_TARGET=win64 CPU_TARGET=x86_64 INSTALL_PREFIX=c:/lazarus/fpcNote that you'll need full fpc source since you need to build the cross compiler as well (instead of just the units). Last stable lazarus installer I use only have 'packages' and 'rtl' folder under source directory.

Thank you friend!!

I will have to agree, you should definitely use virualization..  Its very simple to download the virtualbox... Once your done with that just install the lazarus and compile..  Trust me its not hard to do at all..

I have W7/64 with lazarus 64, and I have same virtual machines, one with linux, other with linux/64, and other with XP

All VM, with their lazarus, and I use it, for compiling and test my applications.

Give it a try.
