Bitbake error

[burru0]

I'm trying to make the cross-compiling of the library libgfortran on a virtual machine in a windows pc, to later build the library on a linux device. Following the guide I have encountered two problems:

• When I execute the command "git cherry-pick de2aa7a56790581406f219339c9022638cd47494", I get the error "fatal: bad object".

• When I execute "bitbake libgfortran", the following error appears:

  ERROR: Function failed: do_compile (log file is located at /home/burruzola/nilrt/build/tmp_nilrt_3_0_x64-glibc/work/x86_64-linux/automake-native/1.14.1-r0/temp/log.do_compile.4677)

  Although a "build" folder is created with a subfolder for the machine inside it, the .ipk files are nowhere to be found as the bitbake command is not fully completed.

What instructions are you following? It would probably just be easier to use our binaries if you're going to run on a roboRIO.

I'm following the instructions on the 2016 branch "roborio-packages/atlas_libs/". When the .ipk files have been built, I plant to install them on a sbRIO device.

Heh, those instructions are pretty old, many of the patches you need are already applied. My most recent set of instructions are on the README for https://github.com/robotpy/roborio-atlas . I think I used those mostly untouched for this year (except different fortran versions).

Good luck!
