Hello there,

So compiling on the pyra works well, but for larger project at some point a cross-compiling toolchain will be usefull.
This is my attempt. Sources are : https://dev.pyra-handheld.com/sebt3/pyra-debian-cross
It is based on debian and heavyly depend on debian. but any version (from strech) and any fork (ubuntu...) should be working.

Installation :
The installation is done by root :
cd /install/dir/you/want
wget https://dev.pyra-handheld.com/sebt3/pyra-debian-cross/raw/master/install.sh
chmod 755 install.sh
./install.sh install

A log will be produced in this directory, feel free to read it/ delete it/whatever. Running the installer many time on the same destination directory is safe and wont break everything.

It is possible to choose the install directory using the script options (see -h), although you'll use the install script to update your toolchain, so I recomand the keeping the install script in the destination directory.

Maintenance :
Unlike yactfeau, this toolchain doesnt come with everything installed initially. To keeps things easy, the install script have a number of usefull functions to help you install new development files and keep the rootfs up to date.
Here are a few commands availables (see -h for more details) :
./install.sh pyra.update
./install.sh pyra.upgrade
./install.sh pyra.install libgtk2.0-dev
./install.sh pyra.build-dep audacious

Using it :
There's an environment-setup file available that you can load with :
export TOOLCHAIN_ROOT=install/dir/you/used;. $TOOLCHAIN_ROOT/environment-setup
Alternatively, you can setup your bashrc file (like yactfeu had) with :
./install.sh setup.bashrc

Example usage for a dosbox dbp :
Provided you have run setup.bashrc in your user (or used that export... just before), create the project :
pyra_makeprj dosbox
Get the sources :
svn checkout https://svn.code.sf.net/p/dosbox/code-0/dosbox/trunk dosbox-svn
cd dosbox-svn
Configure them :
./autogen.sh
pyra_addfastmath
pyra_configure
Compile :
make -j 4
Install :
pyra_makeinstall​
Update the default.desktop to setup the packaging information :
vim $PRJ_TARGET/meta/default.desktop
Build the dbp :
pyra_makedbp
Copy on your pyra and test ;)

There's also available :
pyra_cmake
pyra_setprj

this might evolve as I use it

Thanks for deploying, but ..... :)

New fresh debian 9 (stretch) in a virtual box, minimal system,

First part is working on debian

until "./install.sh pyra.upgrade"

After this operation, 0 B of additional disk space will be used.
Setting up openjdk-8-jre-headless:armhf (8u151-b12-1~deb9u1) ...
the java command requires a mounted proc fs (/proc).
dpkg: error processing package openjdk-8-jre-headless:armhf (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of openjdk-8-jre:armhf:
openjdk-8-jre:armhf depends on openjdk-8-jre-headless (= 8u151-b12-1~deb9u1); however:
Package openjdk-8-jre-headless:armhf is not configured yet.

dpkg: error processing package openjdk-8-jre:armhf (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
openjdk-8-jre-headless:armhf
openjdk-8-jre:armhf

ok, whatever , check setup your dosbox sample:

Working until "pyra_configure" ;)
checking for arm-linux-gnueabihf-ranlib... arm-linux-gnueabihf-ranlib
checking for sdl-config... /home/thomas/projects/pyra/bin/sdl-config
checking for SDL - version >= 1.2.0... cross compiling; assumed OK...
yes
checking SDL version only being 1.2.X... no
configure: error: Only libSDL 1.2.X supported

Mhm, adding sdl 1.2
sudo apt-get install libsdl1.2-dev libsdl-net1.2-dev libsdl-mixer1.2-dev libsdl-gfx1.2-dev libsdl-image1.2-dev

but dosn't help.

What i'm doing wrong?

Hoo, oups. I had this setup at some point, but commented out since I wasnt sure that was usefull. Fixed (just uncomment line 328)

Hey you havent finished the installation, dont expect it to work ;)
Once you've uncommented the line, restart the script as it actually install the missing piece in the rootfs to allow compiling with sdl.

Mhm, adding sdl 1.2
sudo apt-get install libsdl1.2-dev libsdl-net1.2-dev libsdl-mixer1.2-dev libsdl-gfx1.2-dev libsdl-image1.2-dev

but dosn't help.

What i'm doing wrong?
You're installing on your host and expect your target to see it ;)
The correct installation would have been :
/path/to/install.sh pyra.install libsdl1.2-dev libsdl-net1.2-dev libsdl-mixer1.2-dev libsdl-gfx1.2-dev libsdl-image1.2-dev
But since just running the script with the install argument to the end will do it for you, just rerun the install script :p

ok, uncomment line 328 in "install.sh"

login in as root, rerun script "./install.sh pyra.update"
and see

./install.sh: Zeile 37: resize: Kommando nicht gefunden.
=> command resize not found

search for "resize" has too many results, what is missing?

The resize command is part of the xterm package. But as this is not realy needed, i've fixed my code again. thanks for the report.

I start with a new minimal system, install packages ssh, wget, curl, xterm, zip and subversion

create a directory projects in my home directory
create a directory projects/pyra
cd projects/pyra
switch to root (su)
Running all commands as root until

"./install.sh pyra.upgrade"

without any error.

logout as root, login with user account and call
"./install.sh setup.bashrc"
logout and relogin so changes in .bashrc are active.

running as normal user
cd ~/projects
pyra_makeprj dosbox -> auto cd into "~/projects/pyra/dosbox"
svn checkout https://svn.code.sf.net/p/dosbox/code-0/dosbox/trunk dosbox-svn
cd dosbox-svn
./autogen.sh

getting some errors and after installing automake autoconf

autogen.sh
pyra_addfastmath
pyra_configure
make -j 4

are done without any error, great.

inside path "~/projects/pyra/dosbox/dosbox-svn" running

pyra_makeinstall

and got two(!) new directories

first:
~/projects/pyra/dosbox/target
with 3 directories
-- icons
-- meta
-- root (but this is empty)

second:
~/projects/pyra/target
with 1 directory
-- root
contains
-- root/bin/dosbox
-- root/share/man/man1/dosbox.1

so, i believe there is going something wrong. I copied "~/projects/pyra/dosbox/target" into "~/projects/pyra/target"

and call "pyra_makedbp" inside "~/projects/pyra/target"

This creates a file "~/projects/pyra/DBPs/.dbp" with 1,3MB size.

Generally it works, but minor changes still need to be done
-- Wrong destination directory of compiled binaries "~/projects/pyra/target" instead of "~/projects/pyra/dosbox/target"
-- "pyra_makedbp" seems to working always in "~/projects/pyra/target" instead of local directory
-- Missing filename in dbp - name

Great work, sebt3

Sound like at some point $PRJ wasnt set correctly. I'll have a look at that issue. Thanks for reporting
EDIT: yup, found&fixed

deleted "~/projects/pyra/dosbox/target" and "~/projects/pyra/target"
downloaded new "https://dev.pyra-handheld.com/sebt3/pyra-debian-cross/raw/master/install.sh"
"./install.sh setup.bashrc"
relogged in
called pyra_setprj dosbox
cd "~/projects/pyra/dosbox/dosbox-svn"
make clean
make -j 4
pyra_makeinstall
-- No errors visibele but i see double slahes "dosbox/target/root//bin" and "dosbox/target/root//share/man/man1"

result:
One directory "~/projects/pyra/dosbox/target", but only contains
-- root
-- root/bin/dosbox
-- root/share/man/man1/dosbox.1

No meta, no icon directory.

maybe i have to setup a fresh debian installation and checking, this will done tonight

Which files can be removed after installation?
All the install.log.* files. And you could run a :
./install.sh pyra.apt clean
And that's all the can be deleted safely. But sure if you realy need space, then purging ....rootfs/usr/share will save you some space while not harming the cross-compilation. But further pyra.update/pyra.install might fail.

There must be an fixed path "projects/pyra" or maybe a lower case inside your scripts.

I have installed your script and root fs in "~/Projects/pyra", was a mistake by me. If i create a new project with "pyra_makeprj" the projects is created in "~/projects/pyra".

All works inside "~/projects/pyra" fine, configure, compiling, making dbps.

Why is the DBP create in "~/projects/pyra/DBPs" and not inside my directory like "~/projects/pyra/dosbox/DBPs"?

If i try to create a new project in "~/MyProjects/SingleProject", i expect all files created inside directory "~/MyProjects/SingleProject", and not in a default directory "~/projects/pyra".

Coud you change this behavior? Or, must all work be done in "~/projects/pyra/"?

You're free to set some variables according to your needs. as you said, all these have default values but can be overwritten as you please.
This is the definition of two :
PROJECTS_BASEDIR=${PROJECTS_BASEDIR:-"$HOME/projects/pyra"}
DBPS_TARGETDIR=${DBPS_TARGETDIR:-"$PROJECTS_BASEDIR/DBPs"}
Set theses 2 according to what you want before (or after) loading the environnement-setup.

The environement-setup is built to support my workflow (I even have 2 other functions setup elsewhere : pyra_send, which send the dbp of the current project to my pyra, and pyra_publish which send the dbp on my hosting). Nothing stop you from building your own matching your own workflow.
In fact while the installer and the environnement-setup are part of the same project, they dont depend on each other and can be used separatedly

Wow, you are fast and thanks for help.

I changed in my ".bashrc" your commands to:

export TOOLCHAIN_ROOT=/home/thomas/Projects/pyra
pyra_makeprj() {
export PROJECTS_BASEDIR="$(pwd)"
export DBPS_TARGETDIR="$(pwd)/$@"

. $TOOLCHAIN_ROOT/environment-setup
pyra_makeprj "$@"
}
pyra_setprj() {
export PROJECTS_BASEDIR="$(pwd)"
export DBPS_TARGETDIR="$(pwd)/$@"

. $TOOLCHAIN_ROOT/environment-setup
pyra_setprj "$@"
}

And now it works like i expected
~/test/test2/dosbox
~/test/test2/dosbox/dosbox.dbp
~/test/test2/dosbox/dosbox-svn
~/test/test2/dosbox/target
~/test/test2/dosbox/target/icons
~/test/test2/dosbox/target/meta
~/test/test2/dosbox/target/root

@Linux-SWAT
Sorry, i delete my post, cause there was a missunderstanding by me, so now wrong post order :)

So, sebt3 shoud move these commands from ".bashrc" to ".profile"?

Seriously he is nitpicking here. While he is right in theory, in practice, even debian use bashrc (have a look at /etc/skel). Beside some shells might not like some syntax in here (like tcsh).
So either way is fine. I'll keep to the safe side : aka do like debian does.
