无法在 Mac OSX (Yosemite) 上安装 RNNLIB (http://sourceforge.net/p/rnnl/wiki/Home/)

Question

说明在这里：http://sourceforge.net/p/rnnl/wiki/Home/

我在 RNNLIb 文件夹的根目录中键入 ./configure。

输出：

似乎令人不安

    checking malloc.h usability... no
    checking malloc.h presence... no

和

    checking for main in -lnetcdf_c++... no

所有 return 没有。

然后我输入 make，我得到：

我不确定如何解决这个问题。是什么导致了这些错误，我该如何摆脱它们？

看起来这是为 GNU C++ 编译器设计的（不是在 Yosemite 中伪装成 g++ 的 Clang 编译器），所以用那个编译器编译会更容易。

如果你没有Homebrew package manager，你可以通过执行安装它：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

现在通过运行ning 安装 gcc 4.9:

brew install gcc49

GNU C++ 编译器现在可用 g++-4.9。

接下来，必须安装 netcdf 库的兼容版本（不是最新版本）。参见 this Whosebug question, or just download ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-cxx-4.2.tar.gz

提取 netcdf 版本后，cd 进入输出目录，运行以下内容（注意 CXX=g++-4.9 使用该编译器构建而不是默认值):

CXX=g++-4.9 ./configure
make
make install
make check

现在回到 rnnlib 本身：

您仍然需要应用一些补丁才能使 rnnlib 与 g++-4.9 一起编译（但比使用 Clang 时补丁更少），如 this sourceforge thread 中所述。

需要移动四个 range_min_size 模板函数的定义，然后才能在 src/Helpers.hpp 中首次使用它们。 src/Container.hpp 也需要一个小补丁来调用 resize() 方法作为 this->resize()。这是补丁：

或者从 Github 要点下载这个补丁，因为它不太容易出错：https://gist.github.com/0David/13d872c88172c75d4663

您可以通过 cd-ing 进入您的 rnnlib 目录并运行ning:

来应用它

patch -p1 < ../patch.txt

（将 patch.txt 替换为您命名的上述补丁文件）。

现在您必须再次运行 configure 指定 g++-4.9（因此它将选择我们刚刚构建的 netcdf 库），然后 make:

CXX=g++-4.9 ./configure
make

现在您将拥有一个可用的 bin/rnnlib 可执行文件（如果您愿意，可以使用 make install 安装）。

如果您确实需要 Clang，那么 this Whosebug question 会涉及导致您在问题中显示的编译错误的问题，因此需要更新 src/Helpers.hpp 以替换 t.get<0> 与 t.template get<0>，但除此之外还有进一步的编译问题，因此仅使用 GNU C++ 构建更容易。

It seems troubling that

checking malloc.h usability... no
checking malloc.h presence... no

你不用担心这个； malloc.h 不是标准头文件（malloc 在 stdlib.h 中声明）。例如参见 [=52=].
