Steps to reproduce:

I was trying to build B2G for hamachi phone (Alcatel One Touch Fire) on my Ubuntu 12.04 x86_64. Following the official wiki, I did these steps:

1. I installed the prerequisites:
$ sudo apt-get install autoconf2.13 bison bzip2 ccache curl flex gawk gcc g++ g++-multilib git ia32-libs lib32ncurses5-dev lib32z1-dev libgl1-mesa-dev libx11-dev make zip openjdk-6-jre openjdk-6-jdk android-tools-adb android-tools-fastboot
GCC is in version 4.6.3.

2. I successfully connected the phone, seen in adb devices.

3. I cloned the repo and successfully configured the project:
$ git clone git://github.com/mozilla-b2g/B2G.git
$ cd B2G && ./config.sh hamachi

4. I tried to build the project:
$ ./build.sh -j1 showcommands


Actual results:

Build failed on this command:

Expected results:

The build process should succeed.

Was this ever resolved? I just started getting this building for the Flame like a week ago on Fedora 20 - I'm not sure what changed as things were building fine prior to that and I didn't consciously change anything (but I may have done system updates and I did update the b2g build tree).

The output in comment 0 shows a mismatch in the compiler being used for building: the regular host compiler (cc) is being used instead of the ARM cross-compiler. This sounds either like a build system issue or something caused by an environmental variable incorrectly set.

Comment 3

[Chris Lord [:cwiiis]]

I noticed I still had a TARGET_TOOLS_PREFIX pointing to an old pre-built toolchain that doesn't seem to be necessary anymore. Removing that appears to have fixed the issue (which is I assume that gcc 4.4.3 isn't supported anymore).

Good, I'm closing as WORKSFORME then.
