[mihini-dev] Mihini Cross Compilation

[mnerys@xxxxxxxxxx]

Hello All,

I'm doing some more debugging and I
had some issues with my Mihini cross-compilation. I saw that the "Run
As" approach in LDT, the runtime was looking for some packages under
the directory /opt/[...]. Instead of instructing the "Run As"
approach to look for the .so in a different location than "/opt/[...]",
which I am not really sure how to do, I decided to give a try to the Cross
Compilation, so that I could use my own .deb with dpkg to place the files
at the default locations.

After some time, I figured out that
we're supposed to use a 32 bit OS with the Linaro toolchain, so I edited
the page:

http://wiki.eclipse.org/Mihini/Cross_Compilation

to include this:

Please, note that these steps have
been validated on a 32 bit OS. Trying to run it on a 64 bit OS may give
you errors when trying the build.sh .

You can see the error that I has having on my 64 bit Debian at the end of this message (in summary: The C compiler
  "/home/marcelo/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian//bin/arm-linux-gnueabihf-gcc"
  is not able to compile a simple test program.).

On a 32 bit Debian, everything went fine.

However, since I wanted to give a try to the devicetree GPIO approach, I tried to do:

make gpio
make make agent_treemgr_gpio

but these did not succeed. Doing the

make package

didn't seem to be building gpio ou agent_treemgr_gpio modules.

I do not know much about building these libraries, so if you can fix this issue or give me good pointers/background on how to investigate/fix it, I'd really appreciate.

Thanks,
Marcelo
