[GRASS-dev] Grass SVN in Android, display issue

[Chemin, Yann (IWMI)]

Hi Markus,

Rooted the Android 4.0.3, installed an Ubuntu arm img, apt-get update, apt-get install grass-dev, apt-get install <additional GRASS dep>, svn co trunk , conf, make, make install, (compiled required stuff within the img Linux CLI), got stuck with GUI, but eventually all went well as androidVNC has a Send Key button (ctrl+shift+t calls the terminal in Ubuntu, then it is as usual: grass70 is responding well). 

On Archos 80 g9 Turbo (dual-core) I thought make -j2 would do it, bad idea, /tmp gets flooded and just refuses files with a no space left warning.

Would like to indulge in your version of things, let us speak a bit off ML. However, there will be a problem: GUI.
wxPython is not even close to alpha release on Android. So it will be a problem down the road.

Why GRASS GIS on Android? For fun first, for work later. Did learn few things on the way, that was fun. I needed a half Kg programming machine for on-the-road GRASS/GDAL stuff with OpenMP, thought that if GRASS would compile its trunk in one way or another in that dual-core Android, then I would be keeping the device and ditch nettop/micro-laptop etc...

Cheers,
Yann

Just curious: did you compile GRASS 7 on Android?

I just tried with a cross compiled
(arm-gp2x-linux-gcc-c++-4.1.2-13.fc17.x86_64),
using Marco Bernasocchi build scripts from QGIS
and got quite a bit compiled.

A few issues are in the library part:

ls.c: In function 'G_ls_format':
ls.c:173: error: storage size of 'size' isn't known
make[3]: *** [OBJ.arm-unknown-linux-androideabi/ls.o] Error 1
make[3]: Leaving directory `/home/neteler/grass70/lib/gis'

--> use #ifdef __ANDROID__ ?

Then:

cd OBJ.arm-unknown-linux-androideabi &&
GISRC=/home/neteler/grass70/dist.arm-unknown-linux-androideabi/demolocation/.grassrc70
GISBASE=/home/neteler/grass70/dist.arm-unknown-linux-androideabi

make[5]: *** [OBJ.arm-unknown-linux-androideabi/test.tmp] Error 126

Some Makefile issues:

Eventually I didn't get the link to PROJ4 right, so subsequent compilation
of modules depending on that naturally fails. But I didn't spend time on
this.

Not sure how to solve above issues:

PS: Maybe it is useless to run GRASS on Android but maybe not.. :)
