Installing required packages (Ubuntu 12.04)
Building on Ubuntu 12.04 is currently only experimentally supported and is not guaranteed to work on branches other than master.
$ sudo apt-get install git-core 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 openjdk-6-jdk 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
Then you need to do below change:
Simply change build/core/combo/HOST_linux-x86.mk line 61:
-HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0
+HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0
His commit message is as follows:
HOST_linux-x86: Avoid doubly define macro _FORTIFY_SOURCE
While building Android with latest host gcc,
it causes the following build error:
Install: out/host/linux-x86/bin/mkbootimg
host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp
:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
:0:0: note: this is the location of the previous definition
cc1plus: all warnings being treated as errors
In order to make build system happy, this patch does unset macro
_FORTIFY_SOURCE and then define it in host cflags.
If there have below error log:
Host OS: Linux 3.0.0-12-generic #20-Ubuntu SMP x86_64 GNU/Linux gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1 Compiling Android from git (master) stops with error: android_repo/external/llvm/lib/Support/Threading.cpp:96: undefined reference to `pthread_create' android_repo/external/llvm/lib/Support/Threading.cpp:91: undefined reference to `pthread_attr_setstacksize' android_repo/external/llvm/lib/Support/Threading.cpp:100: undefined reference to `pthread_join' out/host/linux-x86/obj/STATIC_LIBRARIES/libLLVMSupport_intermediates/libLLVMSupport.a(Mutex.o): In function `MutexImpl': android_repo/external/llvm/lib/Support/Mutex.cpp:69: undefined reference to `pthread_mutexattr_init' android_repo/external/llvm/lib/Support/Mutex.cpp:75: undefined reference to `pthread_mutexattr_settype' android_repo/external/llvm/lib/Support/Mutex.cpp:80: undefined reference to `pthread_mutexattr_setpshared' android_repo/external/llvm/lib/Support/Mutex.cpp:89: undefined reference to `pthread_mutexattr_destroy' out/host/linux-x86/obj/STATIC_LIBRARIES/libLLVMSupport_intermediates/libLLVMSupport.a(Mutex.o): In function `llvm::sys::MutexImpl::tryacquire()': android_repo/external/llvm/lib/Support/Mutex.cpp:143: undefined reference to `pthread_mutex_trylock' collect2: ld returned 1 exit status
Solution:
Add "LOCAL_LDLIBS := -lpthread -ldl" in external/llvm/llvm-host-build.mk
Have Fun!!
