GTK CrossCompile in Windows

Hi,

I have managed to set up the environment for cross compiling applications using Eclipse + Cygwin for standard C/C++ applications. I have also managed to cross-compile some libraries like lusb but now I am trying to set up an environment for GTK.

I have solved lots of errors but now I am stucked with -lffi not found error. I have check that the library is correct in /usr/lib but I get this error

Code: Select all

Has anybody manged to set up a Windows Cross Compilation environment for GTK applications?

Thank you in advance,

Solved! i don't know why pkg-config did not ask for -lffi if I compiled in the raspberry PI and using the Cygwin version of pkg-config it needed.

I installed the libfffi-dev in the raspberry Pi and copied the libraries to my folder in Windows using rsync and now It works fine. Later I met some problems with the linker but there is another post in the forum with that problem.

The linker does not find some libraries. So it is necessary to use the -rpath-link option for the linker.

Code: Select all

-Xlinker -rpath-link=/home/phate/rpi/chroot-raspbian-armhf/usr/lib/arm-linux-gnueabihf 
-Xlinker -rpath-link=/home/phate/rpi/chroot-raspbian-armhf/lib/arm-linux-gnueabihf
So now I can Cross Compile GTK in Windows using Cygwin and Eclipse. If somebody needs help could ask here. I folowed some instructions in Internet and solved some problems during compilation and linking:

http://www.raspberry-projects.com/pi/pr ... ng-eclipse
http://hertaville.com/2012/09/28/develo ... -compiler/
http://www.raspberrypi.org/phpBB3/viewt ... 33&t=37658

To avoid cross-compile the whole gtk I installed all the needed libraries in Raspberry PI and then copied into my computer using rsync to preserve the links.

Hi Daniel, I´m trying to do the same on linux(Ubuntu) but I don´t know with files ( libs and includes ) I need to copy to linux and to where ( directories ). Please can you give some tips?

Thank in advantage,

Geraldo

Hi Geraldo,

I installed rsync in the raspberry PI and run rsync daemon to copy all the files and preserve the links

You should rsync the /lib and /usr/lib folders to your Ubuntu path.

You can take a look to this link in step 3:
