我看了那么久的文档，都不知道怎么使用，比如在手机上识别手写数字

@Xreki 那命令之前看过，最后的那部分不知道怎么做，你们努力，我为你们打call，我也要好好学习，看能不能为paddlepaddle贡献点什么。

@Xreki 我安装你给的这个教程在第二步的make时报错

不知道是不是我的go的版本问题，我的版本是go version go1.6.2 linux/amd64

最后的那部分不知道怎么做

是说Run the demo program by logging into the Android environment via adb and specifying the PaddlePaddle model from the command line as follows这部分吗？这部分是通过Android的adb工具，将生成的二进制文件传输到Android手机上，然后adb shell登陆到Android手机上，以命令行的方式执行可执行程序，遇到什么问题可以详细地在这里列出来。另外，我们的文档也有不完善之处，欢迎多多提建议。

你们努力，我为你们打call，我也要好好学习，看能不能为paddlepaddle贡献点什么。

多谢你的支持，非常欢迎你的贡献。

你是自己搭建交叉编译环境来编译Android版本吧。这个错误跟go的版本没关系。具体贴一下你的cmake命令和cmake输出吧。

@Xreki 我执行的cmake是：

你这是在编译Android版Paddle吧，可能我们的文档让你误解了。

编译Android版Paddle（http://www.paddlepaddle.org/docs/develop/documentation/zh/mobile/cross_compiling_for_android_cn.html#linux ），按照这个步骤来：

  • 下载NDK，生成自己的独立工具链
  • 配置cmake：
mkdir build
cmake -DCMAKE_SYSTEM_NAME=Android \
      -DANDROID_STANDALONE_TOOLCHAIN=/home/wang/ubuntu/paddlepaddle/android/arm_standalone_toolchain \
      -DANDROID_ABI=armeabi-v7a \
      -DANDROID_ARM_NEON=ON \
      -DANDROID_ARM_MODE=ON \
      -DUSE_EIGEN_FOR_BLAS=ON \
      -DCMAKE_INSTALL_PREFIX=/home/wang/ubuntu/paddlepaddle/android/install \
      -DWITH_C_API=ON \
      -DWITH_SWIG_PY=OFF \
      ..
make
make install

以上是https://github.com/PaddlePaddle/Mobile/blob/develop/benchmark/tool/C/README.md 里面的第1步。然后再依次按文档执行第2,3,4步。

是的，我是安装步骤一步步来的，我出错的是第2步的，下面的命令

cmake .. \
-DANDROID_ABI=armeabi-v7a \
-DANDROID_STANDALONE_TOOLCHAIN=/home/wang/ubuntu/paddlepaddle/android/arm_standalone_toolchain \
-DPADDLE_ROOT=/home/wang/ubuntu/paddlepaddle/android/install \
-DCMAKE_BUILD_TYPE=MinSizeRel

Compile inference.cc to an executable program for the Android environment as follows:
这句话不是很了解，我是要编译inference.cc，还是只执行下面的那些命令？

确认一下，第一步，你已经成功编译了PaddlePaddle库了吗？
从#43 (comment) 的cmake的输出来看，这是在配置Paddle，而不是inference这个demo啊。

Compile inference.cc to an executable program for the Android environment as follows:

这句话，是教你配置和编译inference.cc，你需要进入到Mobile/benchmark/tool/C这个目录，然后执行下面的命令配置和编译。make完了之后，你会在build目录下看到inference这样一个可执行文件。

我明白了，因为在第一步的时候，我是在paddle的根目录下执行cmake的，所以我在第二步时，也就习惯在paddle根目录下执行那些命令了，所以才会出现这些问题。谢谢你了！

不客气。这个repo下的文档可能描述的不够清楚，我们也会尽快完善，:smile:
