Hello, all!

Sorry about this sooo late reply - I didn't give up, I'm just busy but LO
for Honeycomb is one of my top priorities now.

I'll answer inline.

I didn't know about this problem. I don't have much experience in
cross-compilation (I thought LO had already take care of it) but* *I'll ask
some friends for help.

This is what I have in mind. Develop a new interface for tablets and
commiting it for a public repository (probably Github) so I can get external
help and feedback. "Release early, release often"

Actually I think that today's UI can't be used on a tablet for 2 reasons:

   1. It isn't prepared for this
   2. Would be completely visually unintegrated with the other apps

Maybe making it work could generate interest but I wonder if the efford
would worth it. I really don't know... I'll probably be sure after getting
the cross-compilation work!

Michael, thank you very much for your orientation. Without it I would be
lost. I've subscribed to the dev list, so I can easily comunicate with
others.

Jonathan, let's get our hands dirty and make it work!

Best regards!

Re: [Libreoffice] Android versions that we will compile LO for

[rcsilv...@gmail.com]

Hi, Martin and everybody

I'm one of the "great individuals" Jonathan mentioned (although I'm not so
great like he said :P).

Our plans is to make an LibO version for tablets. Of course, Android API
make it possible to tablet apps run on smartphones as well, but it affects
our target version.

Jonathan, I think it'd be better to target 3.0 for now. I think that most of
the Android tablets will run 3.1 but, let's stick with 3.0 until we have
good reasons to increase our minimum version. What do you think?

Regards!

[Libreoffice] Doubts on Android cross-compilation

[rcsilv...@gmail.com]

Hello, devs!

As some of you might know, Jonathan Aquilina and me are trying to compile
LibO to Android. I'm learning LibO compilation and I'm trying to compile it
following the instructions on README.cross [1]. I'm getting the following
error:

"configure: error: C compiler cannot create executables"

I'm looked for some autogen.sh docs on its site[2] but there isn't. What
docs do you recomend me to read?

I'm using an Ubuntu 11.04 computer for this compilation and first I tried to
run the autogen.sh without running "apt-get build-dep libreoffice" because I
think it's useless when you're using Android NKD toolchain. After getting
this error, I've run "build-dep" but I'm still with the same error. Is it
necessary to have the build dependencies installed?

[1] http://cgit.freedesktop.org/libreoffice/bootstrap/plain/README.cross
[2] http://buildconf.brlcad.org/

Regards!

Hello!

Thank you for your answers.

Yes, I get this error when running the top autogen.sh. I also know it's
experimental and I would run into errors soon. Thats what I want to solve :)
I don't have much experience with C++ build or cross-compilation but I want
to focus on that and learn.

Yes, I also don't think we'll need such a complex process.

I'll do these.

Thank you all! I'll keep you up to date.

Hello, Tor

I've finally could run ./autogen.sh. It was my mistake... Sorry.

Now I'm going through errors and try to solve them, until I can compile it!

Sorry again for my "noobness" and thank you for your patience.

Great! Very good to CC the list. Jonathan (CC'd) already came to me so we
