Theano 找不到 lstdc++

Question

我使用 anaconda2 安装了 mingw 和 libpython，之后我通过在 IDLE 上执行 import theano 来测试运行 Theano，不幸的是我遇到了一个错误，告诉我找不到几个文件。

我去了文件路径C:\Anaconda2\MinGW\x86_64-w64-mingw32\lib发现确实没有-lstdc++这样的文件但是有libstdc++.a,libmingw32.a,libgcc_s.a其余的，只有一个文件我找不到，那就是 lgcc.a 或 libgcc.a。

我怀疑我需要卸载我的 Theano 并重新安装 Bleeding Edge 版本，但我想问一下即使不安装 Bleeding Edge 版本也能解决这个问题吗？或者这真的需要吗？

这是回溯：

Answer 1

给出的确切信息是：

skipping incompatible .../libstdc++.dll.a when searching for -lstdc++
etc..

我还看到它在寻找 user32 和 kernel32，但工具链显然是为 x86_64-w64-mingw32 配置的。

您是否尝试使用 64 位工具链为 32 位系统编译 Theano？你应该检查你的编译器标志。

Answer 2

最后，在32位windows的Anaconda中重新安装mingw和libpython后，升级到最新版本，一切都解决了。我将我的从 2.7.10 更新到 2.7.12。

注意：不要忘记将 Anaconda2 文件夹放在变量环境的 PATH 中。
