ubuntu 15.10 64bit构建Android源5.0版

Question

我该如何解决这个问题？当我使用'make -j4'构建5.0的Android源代码时，它会导致问题。这是错误日志：

Answer 1

仔细检查你已经安装了所有必需的包https://source.android.com/source/initializing.html

Answer 2

在我的情况下，我在Ubuntu 18.04中构建Marshmallow 6.0.1_r1时遇到类似的错误。

如果你得到类似的错误：

build/core/binary.mk:646: recipe for target 'out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp' failed
make: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp] Aborted (core dumped)

仔细看看这条线，它是一个core dumped，所以我使用coredumpctl list，用G导航到列表的末尾，然后找出核心转储执行路径（右列）是prebuilts/misc/linux-x86/flex/flex-2.5.39

而PREBUILT文件显示：

xb@dnxb:~/my_android_src/prebuilts/misc/linux-x86/flex$ cat PREBUILT 
The objects in this prebuilt directory can be rebuilt
using the source archive hosted at

http://sourceforge.net/projects/flex/files/

Commands:

./configure
make CFLAGS="-static" LDFLAGS="-static"
# (Disregard the errors at the end of the build)
rm flex
make CFLAGS="-static" LDFLAGS="-static" flex
# Copy the linker command line, replace it with static libm.a
gcc  -static  -static -o flex ccl.o dfa.o ecs.o scanflags.o gen.o main.o misc.o nfa.o parse.o scan.o skel.o sym.o tblcmp.o yylex.o options.o scanopt.o buf.o tables.o tables_shared.o filter.o regex.o  /usr/lib/x86_64-linux-gnu/libm.a
xb@dnxb:~/my_android_src/prebuilts/misc/linux-x86/flex$ 

就是这样，前两行说你可能需要重建自己，如果出现问题，因为这个flex-2.5.39二进制文件是在另一个平台上预先构建的。

因此，只需解压缩此目录的flex-2.5.39.tar.gz，转到解压缩的flex-2.5.39目录，然后按照上面的PREBUILT指令操作。

简而言之，您需要执行以下步骤：

    cd <ANDROID_TREE_DIR>/prebuilts/misc/linux-x86/flex
    tar -zxvf flex-2.5.39.tar.gz
    cd flex-2.5.39
    make CFLAGS="-static" LDFLAGS="-static"
    rm flex
    make CFLAGS="-static" LDFLAGS="-static" flex
    /bin/bash ./libtool --tag=CC   --mode=link gcc  -static  -static -o flex ccl.o dfa.o ecs.o scanflags.o gen.o main.o misc.o nfa.o parse.o scan.o skel.o sym.o tblcmp.o yylex.o options.o scanopt.o buf.o tables.o tables_shared.o filter.o regex.o lib/libcompat.la /usr/lib/x86_64-linux-gnu/libm.a
    cd ..
    cp flex-2.5.39/flex .
    mv flex flex-2.5.39
    ls -la 
        flex-2.5.39 #### <<- YOUR new generated file
        flex-2.5.39.tar.gz
        MODULE_LICENSE_BSD_LIKE
        NOTICE
        PREBUILT

现在尝试再次做make <module> -j4，不再中止这样的错误。

p / s：如果你看到类似LANG=C make pm -j4的错误消息，替代方式将是LC_*。

p / s2：我还需要symlink ld如下固定'out/host/linux-x86/obj/lib/libart.so' failed和error: unsupported reloc 42：

xb@dnxb:~/my_android_src$ cp prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.15-4.8//x86_64-linux/bin/ld ../ld_bk #backup android source's ld first
xb@dnxb:~/my_android_src$ rm prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.15-4.8//x86_64-linux/bin/ld #remove android source's ld
xb@dnxb:~/my_android_src$ ln -s /usr/bin/ld.gold prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.15-4.8//x86_64-linux/bin/ld #create symlink for android source's ld to system's ld.gold
