无法安装RNNLIB(http://sourceforge.net/p/rnnl/wiki/Home/)在Mac OSX

Question

说明如下：http://sourceforge.net/p/rnnl/wiki/Home/

我打字/在RNNLIb文件夹的根目录中进行配置。

然后我输入make，得到：

我不知道该怎么解决。是什么导致了这些错误，我该如何消除它们？

Answer 1

看起来这是为GNU C++编译器设计的（而不是Yosemite中伪装成g++的Clang编译器），所以使用该编译器进行编译会更容易。

如果你没有Homebrew软件包管理器，你可以通过执行来安装它

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

现在通过运行：安装gcc 4.9

brew install gcc49

GNU C++编译器现在将以g++-4.9的形式提供。

接下来，必须安装兼容版本的netcdf库（而不是最新版本）。请参阅此堆栈溢出问题，或者直接下载ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-cxx-4.2.tar.gz

一旦提取出该版本的netcdf，cd将进入输出目录，并运行以下操作（注意要使用该编译器而不是默认编译器构建的CXX=g++-4.9）：

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程序才能使rnnlib与g++-4.9一起编译（但补丁程序比使用Clang时要少），如本sourceforge线程中所述。

在src/Helpers.hpp中首次使用四个range_min_size模板函数之前，需要移动它们的定义。src/Container.hpp还需要一个小补丁来将resize()方法调用为this->resize()。这是补丁：

或者从Github gist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将其应用于rnnlib目录并运行：

patch -p1 < ../patch.txt

（将patch.txt替换为您命名的上述修补程序文件）。

现在，您必须再次运行configure，指定g++-4.9（因此它将获取我们刚刚构建的netcdf库），然后运行make:

CXX=g++-4.9 ./configure
make

现在您将有一个可运行的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，那么这个Stackoverflow问题涉及到了导致问题中显示的编译错误的问题，因此src/Helpers.hpp需要更新以用t.template get<0>替换t.get<0>等调用，但除此之外还有更多的编译问题，因此使用GNU C++构建更容易。

checking malloc.h presence... no

你不需要担心；malloc.h不是标准头文件（malloc在stdlib.h中声明）。例如，请参阅此堆栈溢出答案。
