恩。如果没记错的话。是好多年前。想把ruby编译到android上运行的问题。我记得那个时候是纠结了一通宵,最后是总算把他跑在了android上。
今天整理一下。
首先 这个教程只限于 ruby1.9.2,为什么?
因为我是过2.1.2。失败!。
首先 先把ruby1.9.2安装上。
./configure
make
sudo make install
一般来讲 = =是没问题的。如果有问题。逐步解决把。这个不在内容内;
首先,重头来看。 其实感觉只要把 gcc 的sysroot 改成NDK中的路径,就应该可以的了。不过事情从是没有那么理想。
./configure
make
出错!。
但是结果是有问题的。 goolge半天,找到了答案。
先做以下变量定义
export NDK_ROOT=~/android-ndk-r9d
export CFLAGS="-march=armv5te -msoft-float "
export SYSROOT=$NDK_ROOT/platforms/android-4/arch-arm
export CC="$NDK_ROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc -mandroid --sysroot=$SYSROOT"
然后有2个补丁文件。
这个是ruby.patch

这2个是补丁文件。
用patch 命令
patch -p0 < ruby.patch
把ndk.patch 放到你的sysroot目录中。
patch -p0 < ndk.patch
执行
patch -p0 < ruby.patch
如果替换出现异常,手动修补一下。
然后。执行。
./configure --host=arm-eabi --disable-ipv6 --prefix=/system/local --enable-shared
make
XDDDDDDDDandroid的ruby.so文件就出来啦。。。。。。。。。。耶!
