Hi,

I am sure taht this question was already asked, but I can not find clear answer.

Is there possibility to create Lazarus application with GUI which will run on Raspberi Pi - ARM - Windows 10 IoT ?
(Target OS=Win32, Target CPU=Arm ?)

If not, is there possibility to create same application for Raspberi Pi
- ARM - Linux ?
(Target OS=Linux, Target CPU=Arm ? ... can I crosscompile from Linux/i386 to Linux/Arm ?)

Thanks

The latter definitely should work. I cannot comment on the former (windows).

From what I've read, I fear not. I haven't tested it yet, but from what I understand, windows IOT uses a subset of the windows api, implemented by a different set of dlls. Besides that I wonder if fpc can generate win32-arm startup code.

Supposedly true. AFAIK there is no support for Win IoT on ARM by fpc. I understand that IoT on ARM is very different form Win CE - but rather similar to Win on X86, so fpc supposedly would need a completely new target.

Yep. We already did test Delphi programs on Win IoT. Win IoT is lacking any GUI API, but in our test, a Delphi generated Service ran on Win IoT X86 without any modification. So a no-GUI Lazarus Program should run, as well.

Is there any tutorial how-to-do-it other than
http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM ?

What I did is:
1. Install Ubuntu Linux 16.04 (64 bit) into VirtualBox on Windows
2. Install Lazarus for Linux (I can compile application for host platform)
3. Try install
https://sourceforge.net/projects/freepascal/files/Linux/3.0.2/fpc-3.0.2.arm-linux-eabihf-raspberry.tar/download using supplied install.sh
(some errors were reported as: Syntax error: Word unexpected (expecting"(") After step 3 I cannot run Lazarus (probably fp.cfg was corrupted)

Well, I can't swear about Linux/i386, but I'm doing it without any trouble under Linux/x86_64, once the proper binutils and other required stuff, such as ARM appropriate libraries are installed. It shouldn't make a difference. On a Raspberry Pi - Arm Linux you can also install Lazarus (I used fcplazup) and compile directly on the target.

Alternate solution to my modified question (Cross-compile from Windows to Linux/ARM):

- Download FpcUpDeluxe executable from
https://github.com/newpascal/fpcupdeluxe/releases (in my case 1.2.0m)
- Run it and choose InstallDir (for example D:\TEMP\fpcupdeluxe)
- Select FPC and Lazarus version (for example FPC 3.0.2 and Lazarus trunk)
- Click "Install/update FPC+Laz" (FPC and Lazarus sources will be downloaded from SVN and build)
- Then select CPU=arm, OS=Linix and click "Install cross-compiler" (cross-compiler and FPC unit will be compiled)

It is easy and awesome! Thank you very much for FpcUp[Deluxe]!

Unfortunately there is not mentioned on:
http://wiki.freepascal.org/Lazarus_on_Raspberry_Pi#Cross_compiling_for_the_Raspberry_Pi_from_Windows and http://wiki.freepascal.org/fpcup#Linux_ARM_cross_compiler , that this whole process is covered by FpcUpDeluxe and user is not required do anything manualy ;-)

P.S.1
Only drawback, which I faced is, that I can not build current stable release of FPC 3.0.2 and Lazarus 1.6.4 using FpcUpDeluxe (fpcupdeluxe-i386-win32.exe on Win8.1 64bit)
Program freezes and last entry in log is: Lazarus: lazbuild could not be found, so cannot build USERIDE.
(configuration which works for me is FPC 3.0.2 + Lazarus trunk)

P.S.2
Interesting idea would be create utility which will build only cross-compilers based on FPC already installed (like does FpcUpDeluxe but without need/overhead of SVN checkout and Lazarus build functionality). May be only ZIP archive with needed utilities + script which will do needed tasks.

Thank you *very* much for that information! If no one else does, I'll try to update those two wiki pages, and also this one: http://wiki.freepascal.org/Small_Virtual_Machines

hi
With this help inf, I could make CudaText for Linux-ARM. Raspberry Pi 3. It works. Thanks for the info.
