I'm new to Haiku. I see that python is installed.

Is there a way to create GUI Apps in python for Haiku?

Hello, I am attempting to build Haiku under Gentoo GNU/Linux, direct to partition. That is, /dev/hda14 has permissions set to allow me to write to it, and UserBuildConfig is as below. However, when GRUB comes to boot from the partition it says that it can't load the image. The command jam @disk mount is able to view the partition, but it shows one top-level directory myfs, under which are apps, common, develop, home, optional, system and var. Surely those sub-directories should actually be in the root, and there should not be the directory myfs ?

Grub entry:

title Haiku
rootnoverify (hd0,13)
chainloader +1

UserBuildConfig:

HAIKU_IMAGE_HOST_NAME = pimple ;

AddUserToHaikuImage mounty : 573 : 100 : /boot/home/mounty : /bin/bash : "Michael Mounteney" ;

Hello,

i currently try to set up a cross development environment on linux to build Haiku/BeOS Applications. I've read the Articles concerning on how to get the latest sources from SVN, build Jam and bootstrap the compiler to target haiku - that's no problem at all and works relativley flawless. So does building targets with Jam (like haiku-image, ...)

But: Now that i have the cross compiler, how to compile a simple application on linux using the cross compiler? When i try to compile a simple application like the obligatory "Hello, World" there are a few issues:

(Please note that i am not a GCC Guru - just used the installed, native compilers until now)

1.) The compiler does not find the necessary header files from the standard c++ libs - you have to supply them by hand using the -I switch or set the CPLUS_INCLUDE_PATH variable to the corresponding directory. Is this something i can configure in some configuration file?

2.) The linker complains that he's missing crti.o and some other bootstrapping objects. They are there somewhere deep inside the "generated/" folder - you have to copy them to the directories where ld looks for them (found out the correct path's via strace)

3.) When linking the libstdc++.r4.so and libbe.so there are a huge amount of missing references -> That's where i stuck at the moment.

So, would it be possible that someone explains (or eventually writes a nice tutorial) on how to get a simple Haiku Application (like let's say "Pulse") to compile on linux and run on haiku?

Thanks,
