We are facing some build errores on Flatfish that can be solved by upgarding the toolchain to a newer one. Right now Flatfish is based un gcc-4.6 (Jelly Bean 4.2), and the plan is to upgrade the toolchain to gcc-4.8 (as we did with ICS devices recently)

Hi Juan,
Do you mean the build break for ?
I try to check the gcc neon capacity before use that.
Yes, this is fixed with gcc-4.8 (and some others related)
In Jelly Bean based systems, toolchains are downloaded to prebuilts/ directory. As we could have two different toolchains to compile Gonk and Gecko, and both are in the same directory, I modified the build system to get the most recent one found. $(wildcard /path/arm-linux-androideabi*/arm-linux-androideabi- ) get a list of directories sorted by name, so the last version should be the last in the list. $(word $(words list ), list) gets the last one.

Another approach could be putting the toolchain alone in a separated directory.

gerard-majax noticed that I was PRing against master. I would like to have these changes in master too, but for this bug I should PR against b2g-4.2.2_r1.

I still cannot build for Flatfish because of :

Yeah, but they are tracked by bug 1121907
Have patches for them too.
