Configuring Lazarus for Android

[ghassen_khalil]

Hi everybody,
Can someone guide me through a tutorial and describe me the necessary steps to generate Android application with Lazarus, I found a lot of informations on forums but it doesn't worked for me and it was uncomplete

Afaik Android is mostly still in development. There is no end user docs and support yet.

[ghassen_khalil]

but there are some peoples that succeeded to build .apk with Lazarus !!!

Yes, we are too geek to make it possible, so you have to be a geek too if you want to be like us
There are at least 2 wiki entries that you have to read:

• This one explains Android support from the compiler side
• This one explains how LCL Custom Drawn is used to create LCL powered Android application. Watch out, the article contains information regarding hacked 2.5.1 & 2.6.1 arm-linux version of the compiler, which even though still capable to generate Android app, but not supported by the compiler team

Thnx, but those two wiki entries are those who troubled me 
Anyway I downloaded the Virtual Box image containing FPC and Lazarus and the whole configuration to build .apk .. and when I tried to compile my own project (not the one given in the examples directory called AndroidLCL) I got an error :

Code: [Select]

Error: can't open Android/lib/arm-linux/unit1.o for reading : No such file or directory

and when I tried to compile my own project (not the one given in the examples directory called AndroidLCL) I got an error :

This is why I said you have to be a geek, where being a geek is to read the wiki thoroughly, not skipping any steps and try to understand the whole concept before proceeding. PATH settings to NDK toolchains and the cross compiler are the most important part. That error might not be the first one, try copy-paste-ing the whole messages (right click->copy all and hidden messages).

Next, you better use androidlcl as a template instead of writing from scratch, because you'll need to setup directory & ant build configuration files to generate the apk.

Do you have -XD$FPCTARGET- in your fpc.cfg? If yes, do you have arm-linux-as and arm-linux-ld accessible from PATH?

I'm newbie to Lazarus and FPC .. I can't understand what you are saying

Then perhaps it's better to learn a bit more before attempting to do this.

Then it's not your time yet to try the Android target.

Does anyone know if someone is trying to integrate some of the process into Lazarus
or are things likely to stay as they are for the foreseeable future.

I think a good starting point is to implement a android moule wizard mimicking the "Apache Module" wizard... but my "proof of concept" is stopped because I could not still solve the problem discussed in...

I just figured it out .. but it's always my time to know new things .. we all started from zero with a little bit of help bro !!

Many great programmers start that way, feel free to follow their way. But I don't suggest jumping to advanced stage if you haven't mastered the basic and intermediate ones.
