Lazarus Cross?

[stocki]

Is it planned to develope a Cross IDE which means e.g. running Lazarus IDE on Win32 and compile project to Win32/Win64/OSX etc. according to Delphi IDE.

Search the wiki for cross compiling/cross compiler. You might be pleasantly surprised.

It's already possible for years, it's just not packaged so by default. What do you think the Code Generator part in Compiler Options for?

CodeTyphon distro which packages windows and linux target, both 32 and 64 bit is already 500 MB in size (zipped!), Lazarus 1.0 for win32 only is 100 MB. It's a big waste of bandwidth instead of downloading just the source code and build everything on your machine. Nevertheless, IF somebody here is willing to create such a package, it should be OK. That big IF thing is one of the show stoppers.

<advertisement>Patches/additions to fpcup welcome.

FPCup currently has a working Win32->Win64 cross compiler module, a Win64->Win32 module waiting for FPC floating point support to improve, and allows writing other plugins (e.g. Linux->Win32).

See fpcup.html in the source for what you need to do (IIRC: 1. Make sure all required binutils are there 2. Write some commands that insert the proper cpu/os options in the build options).</advertisement>

Especially a Linux->Win32 cross compiler might be nice as you can then test the result using Wine....

This is what I already setup in my lovely Kubuntu 12.04
Much better than when I was on Win32, no way to test the Linux version except through VM / reboot.

Very nice! Shouldn't that be included into the standard Lazarus distro?

[BigChimp]

I wouldn't think so as I think this is definitely for everyone - but perhaps an add on .deb and .rpm lazarus_windows_crosscompiler that pulls in the required dependencies, adds the crosscompiler etc. could be nice.
I'm sure the Lazarus team will appreciate a patch for that

I have downloded that monster pack, but in the CodeTyphon Center there is no cross element for Mac. ???

[BigChimp]

That's probably because you need OSX files which CT cannot legally distribute.

See e.g.
http://wiki.lazarus.freepascal.org/Cross_compiling_OSX_on_Linux

It's in our To-Do list and the MAC OS...

I found menu entries for FPC cross build but nothing for building Lazarus e.g. HostWin32_TargetWin64. How is this done?

Choose Project -> Options -> Code generation and choose other settings as needed.
Click Build - that's all.
Next time Cross compile elements will be shown in the CodeTyphon center.

I can compile to Win32 or Win64 on my Linux x64 with CodeTyphon v2.80

[stocki]

Thank you. I understand the handling now.

Neverthless FPC32 build cross element x86_64-win64 gives a "can not find FPC32 binCross files for x86_64-win64"

Are there missing some files in the pack?

On what system you have installed CodeTyphon.

I think that you cannot compile from 32-bit system to 64-bit.

-WinXP 32
-??? Why? Delphi can too. Thats the aim of cross compiling!
