Hi all,

I need a self-build version of b2g to get started with tests for
different WebAPI. But so far I'm struggling in getting the emulator
built at all. So far no-one was able to help me with that problem, but I
hope that a solution can be found here.

So I have followed the steps on MDN and installed all the required
packages, checked out the B2G repository and ran the config script with
'./config.sh emulator'. When I now start build.sh I get a failure quite
early in the process, which doesn't let me continue:

> host C: emulator-common <= external/qemu/distrib/zlib-1.2.3/compress.c

liblto_plugin.so is part of the toolchain and located in:

../prebuilts/gcc/linux-x86/host/i686-linux-glibc2.7-4.6/libexec/gcc/i686-linux/4.6.x-google/liblto_plugin.so

What did I wrong or what's missing so this compile error can be eliminated?

Thanks a lot!

Hi Henrik,

I haven't updated it in a while, but I do have a ubuntu VM with the emulator compiled.
http://shizen008.wordpress.com/2013/11/11/images-for-b2gemulator/

In regards to your situation, I suggest trying the part in the MDN that states to disable the 32 bit compilation.
see solution 2 in https://developer.mozilla.org/en-US/Firefox_OS/Firefox_OS_build_prerequisites
There's a patch to disable the 32 bit compilation.

Regards,
Naoki
