Hi all,

I successfully cross-compiled 'Hello World' for my new Nokia N9. the N9 uses a Linux version. (Called Maemo-6 or Meego-Harmattan, depending on who you ask)

But when I try to link to libc, (for example by adding the cwstrings unit) the application crashes at startup (in _dl_init, called from ld-linux.so)

Most probably because a invalid entry point, the linker gives the following error:

Linking hello
/home/CNOC/joost/QtSDK/Madde/toolchains/arm-2009q3-67-arm-none-linux-gnueabi-x86_64-unknown-linux-gnu/arm-2009q3-67/bin/arm-none-linux-gnueabi-ld: warning: cannot find entry symbol cs=/home/CNOC/joost/QtSDK/Madde/targets/harmattan_10.2011.34-1/specs; defaulting to 0000000000008484 11 lines compiled, 0.2 sec

As you can see I use the toolchain (ld, as and libraries/so-files) from the toolchain from the Nokia-sdk. I don't know what that specs file is for, but it contains the following:

=======
%rename cc1 old_cc1

*cc1:
-march=armv7-a -mcpu=cortex-a8 -mfpu=vfp -mfloat-abi=hard -fno-omit-frame-pointer -fno-optimize-sibling-calls %(old_cc1)

%rename link old_link

*link:
-O 1 --hash-style=gnu -L=/usr/lib/gcc/arm-linux-gnueabi/4.4 %(old_link) =======

Any idea how to proceed?

Never mind, I've found the problem. The linker that I used was actually a wrapper, which called another linker with some extra options. Those options aren't applicable to Free Pascal.

Now it run.

This is really nice, I can just run LCL (qt) applications on that phone. Almost as easy as with WinCE.

The sad part is that the platform was abandoned by Nokia and now is no longer supported by any significant smartphones manufacturer. Buying a N9 was in my plans, but I gave up when Nokia went to the dark side of the force.

I am working hard on LCL-CustomDrawn so hopefully in the not so distant future LCL apps will support Android too very reliably. Actually will support almost anything since the porting requirements will be so dramatically reduced in comparison to now.

I don't care what Nokia does, I bought the N9 just out of fun. And fun it is.

Working with Android may be interesting for commercial reasons, but fpc is also my hobby, and then Android is not interesting at all..
