我试图在ubuntu 15.10中构建android源代码,但是我收到了一个错误.现在我希望你的帮助来构建androID源代码.

including ./tools/external/fat32lib/AndroID.mk ...Starting build with ninjaninja: Entering directory `.'[  0% 1/21542] Ensure Jack server is installed and startedJack server already installed in "/home/smile/.jack-server"Server is already running[  0% 2/21542] Building with Jack: out/target/common/obj/JAVA_liBRARIES/core-all_intermediates/with-local/classes.dexFailed: /bin/bash out/target/common/obj/JAVA_liBRARIES/core-all_intermediates/with-local/classes.dex.rspJava heap spaceTry increasing heap size with java option '-Xmx<size>'Warning: This may have produced partial or corrupted output.ninja: build stopped: subcommand Failed.build/core/ninja.mk:146: recipe for target 'ninja_wrapper' Failedmake: *** [ninja_wrapper] Error 1#### make Failed to build some targets (08:25 (mm:ss)) ####

然后我运行“$java -Xmx2048m”命令,我得到一些代码：

谁能帮我如何增加堆大小？

你的帮助会非常适合我

提前致谢.

smile@smile:~/AndroID$java -versionjava version "1.7.0_91"OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.15.10.1)OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)

解决方法:

我遇到了同样的问题.

问题是运行插孔的虚拟机没有足够的内存.

您可以尝试编辑jvm命令：

JACK_VM_COMMAND=${JACK_VM_COMMAND:="java -Xmx4096m"}

或减少并行插孔编号的数量

SERVER_NB_COMPILE=2

在〜/ .jack文件中.

有关详细信息,请阅读jack documentation.

编辑：
更改.jack文件对我不起作用.
在深入挖掘后,我发现jack服务器是以/ host / linux-x86 / bin / jack-admin脚本启动的,它的参数可以通过JACK_SERVER_VM_ARGUMENTS环境变量传递.

所以我的解决方案是在构建aosp之前设置它并重新启动jack服务器：

export JACK_SERVER_VM_ARGUMENTS="-Dfile.enCoding=UTF-8 -XX:+TIEredCompilation -Xmx4096m"out/host/linux-x86/bin/jack-admin kill-serverout/host/linux-x86/bin/jack-admin start-server
