I ran into a few errors when I tried to compile Android on my Ubuntu 12.04 64-bit laptop. Here are my notes on fixing them and compiling successfully: Wrong Java VersionI have the Java 6 OpenJDK, version 1.6.0_24. This meets the android Java requirement for 1.6.0, but I found (later in the build process) that Android really needs to be built by Sun’s Java SDK. In the meantime, the _24 suffix doesn’t check out in Android’s makefile, which produces the error You are attempting to build with the incorrect version of java before exiting:
Commenting out the $(error stop) statement from build/core/main.mk on line 131 will allow compilation to proceed:
make will display the error message, but continue compiling. However, compiling with OpenJDK will probably create problems later in the build process(in out/target/common/obj/APPS/CtsVerifier_intermediates/classes-full-debug.jar). To fix the problems, Sun’s Java SDK will need to be installed. Installing the Sun Java 6 JDK in Ubuntu 12.04To fix the make: *** [out/target/common/obj/APPS/CtsVerifier_intermediates/classes-full-debug.jar] Error 41, get the most recent Sun JDK from here. Once you’ve downloaded it, install it and run update-alternatives so your system uses the Sun JDK:
To verify that the installation was successful, check Java’s version. It should now show that the Sun JDK is running instead of IcedTea:
To revert the changes after Android has been compiled, run update-alternatives to switch back to OpenJDK. error: “_FORTIFY_SOURCE” redefined [-Werror]This is a well-known error caused by the redefinition of _FORTIFY_SOURCE in build/core/combo/HOST_linux-x86.mk. It doesn’t happen on all systems. In fact, the error didn’t appear for most people in Ubuntu 11.04, but it started showing up after 11.10. The error can be fixed by changing the HOST_GLOBAL_CFLAGS on line 56 from
to
Undefining and redefining the _FORTIFY_SOURCE macro somehow fixes the issue. The “_FORTIFY_SOURCE redefined” error was initially discovered by a CyanogenMod developer. external/mesa3d/src/glsl/linker.cpp:1394:49: error: expected primary-expression before ‘,’ tokenI was compiling Android with gcc/g++ 4.6. This error can be solved by downgrading to gcc/g++4.4
To reverse the changes when you’re done with them, reverse the instructions:
If your system is like mine, Android should have compiled successfully. You can test the build by running the emulator command, which is automatically added to your path after compilation. The result:
