Question

我使用anaconda2来安装mingw和libpython，然后我通过在IDLE上导入theano来测试运行Theano，不幸的是我遇到一个错误，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，我发现确实没有名为-lstdc ++的文件，但是有libstdc ++。a，libmingw32.a，libgcc_s.a其余的，只有一个我找不到的文件，那就是lgcc.a或libgcc.a。

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

这是追溯：

Answer 1

给出的确切信息是：

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

我也看到它正在寻找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上的Anaconda中重新安装mingw和libpython之后，一切都通过升级到最新版本来解决。我从2.7.10更新到2.7.12。

注意：不要忘记在变量环境中将Anaconda2文件夹放在PATH上。

Theano找不到lstdc ++
