Universal Flasher: .so file question

billyfred · 06-06-2009, 12:08 PM

Hi all,
here is a question about the "libfskLoad.so" file in the universal flasher. (thanks to Igorsk by the way) Igorsk might be the one who answers it.
And maybe the answer will be usefull for other developpers too

Igorsk, how did you create the shared object file (.so) for the flasher ? Did you use a cross-compiler tool ?
I'm asking because I'd like to create simple programs for the reader. And maybe eventually try to make a port of gnuchess if its possible. If it works, I will post it on mobileread !

Yes, I used a cross-compiler. You can run simple programs using the "run script" option of the Universal Flasher.

Ok, thanks for the quick answer.
Could you tell me where I can get the cross-compiler ?
I found this thread about cross-compiling : https://www.mobileread.com/forums/showthread.php?t=9071
Is this the one you used ?

If you are interested in building for PRS-505, you can use crosstool-4.2 with gcc 2.95. Read this.

The binary modules will not be compatible with PRS-700 though. For PRS-700 you can use Sourcery G++ Lite EABI (based on gcc 4.3). You can find it here. I am sure you can find other distros of EABI gcc 4.3 that will work as well.

ok, thanks guys for your answers and time.
I'll start playing around with the compiler.
As for gnuchess, I'll try to port it but it might take me 1 month or a year, i don't know.
I'm just a beginner with this.
Thanks again
