Keon build error! (Mac OS)

[Francisco Mosquera García]

Hi everyone. I'm getting an error when trying to build FFOS for the Keon:

make[3]: *** [../external/compat-wireless/net/wireless/core.o] Error 8
make[2]: *** [_module_../external/compat-wireless] Error 2
make[1]: *** [sub-make] Error 2
make: *** [external_compat_wireless] Error 2
make: *** Waiting for unfinished jobs....

I'm using a Mac and I know is something bad configured on my computer but can't find/figure out what it is. Thanks!!

You cut interesting part of the error message, but I'll take a guess
that it is because you are on a Mac. You need a case sensitive file
system do build the kernel.

Any tips of what do I have to do to make it run?
I'm not an expert with kernel and I'm going crazy with this error.

This is the whole code that throws the error:

From this point, there is the text I showed before.

Thank you very much for your answer.

You can't build the Keon's kernel on Mac, only on linux.

It's trying to run the linux version of arm-eabi-gcc, while it should be running the one from the prebuilt/darwin-x86 directory.
I run into the same issue for Peak. I'll try and fix that later, but i'm not sure if that's the only problem.

Cheers,

As far as I can tell, you can't build for Peak/Keon on OSX, because they
build the Linux kernel and kernel modules, which are not buildable under
OSX as far as I know.

Hi Dennis, has this been repaired? Would I have to rsync to get the changes that you might have made or do I have to wait until a new commit/pull request is shown on https://github.com/mozilla-b2g/B2G/commits/master

thanks

Didn't get around to look into the build system and properly fix it, but symlinking the B2G/kernel/../prebuilt/linux-* directories to the B2G/kernel/../prebuilt/darwin-* directories allowed me to build a working image for the PEAK.

Cheers,
Dennis

It builds just fine, if you follow the instructions on developer.mozilla.org (especially the case sensitive filesystem parts)

I had to do 3 extra things (For the record, i'm using OSX 10.8.3):
- elf.h was not on the build path. I symlinked external/elfutils/libelf/elf.h to /usr/local/include
- incorrect arm-eabi-gcc is selected. I symlinked B2G/prebuilt/linux-* to B2G/prebuilt/darwin-*
- gnu-sed is needed. brew install gnu-sed. Make sure /usr/local/bin is on your path before /usr/bin.

Cheers,
Dennis

Thanks Dennis. It´s worked for my KEON on the first attempt. However, I didn´t set up a case-sensitive image as per the recommendation, but it still seemed to build fine. (I´m on OS X 10.7.5)
Being new to everything B2G, I thought that I had to symlink those directories myself, but I see that its something you had taken care of.

Please file bug reports about at least the first two items there, if you
haven't already. People shouldn't need to symlink target headers into
the host's /usr/local/include, and it certainly shouldn't be the case
that `setpaths` in build/envsetup.sh sets $prebuiltdir (which I think is
where that part of $PATH should be coming from) to a linux-* tree when
run on a Mac.

I have no external/elfutils in my B2G tree :(

[Francisco Mosquera García]

Hi everyone.
Thanks for the tips, but I also have problems finding the external/elfutils folders. Any help?

Thanks!
