gingerbread-release | in bootable/bootloader/legacy

and I used these command

source build/envsetup.sh
lunch aosp_arm-eng
make

but after a while the compile is stopped ,and show errors below:

I have no idea why this occurs. I didnot change any code.

Answer 1

Your error is generated by the build/make when AOSP was trying to build a Chromium (the default Android browser) library.

You're trying to compile on branch android-2.0_r1 right? This demands Ubuntu 12.04 LTS as stated by AOSP Docs. Are you sure that you have installed all needed tools (and that none of them generated errors during their installs)? You can install these tools by running:

$ sudo apt-get install git gnupg flex bison gperf build-essential \
  zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
  libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
  libgl1-mesa-dev g++-multilib mingw32 tofrodos \
  python-markdown libxml2-utils xsltproc zlib1g-dev:i386
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

Let me give some hints:

1. When you run $ lunch aosp_arm-eng you must remember that this is a "generic" build. It is much more effective if you choose the correct build in this step, for example $ lunch aosp_hammerhead_userdebug. Maybe you're even trying to build in wrong architectures by calling this generic build, or to a wrong devices;
2. Remember to call make clean and/or make clobber before building, to clean possible garbage from previous builds.

I hope that some of above can help you.
