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

Instructions are Here: http://sourceforge.net/p/rnnl/wiki/Home/

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

I type ./configure in root directory of RNNLIb folder.

在RNNLIb文件夹的根目录中键入./configure。

Output:

所有返回no。

Then I type make, and I get:

然后输入make，然后得到:

I'm not sure how to fix this. What is causing these errors and how do I get rid of them?

我不知道该怎么解决这个问题。是什么导致了这些错误，我如何摆脱它们?

Looks like this was intended for the GNU C++ compiler (not the Clang compiler masquerading as g++ in Yosemite), so it will be easier to get this compiling with that compiler.

看起来这是为GNU c++编译器而设计的(不是在Yosemite中使用g++的Clang编译器)，所以用编译器编译这个编译器会更容易。

If you don't have the Homebrew package manager, you can install it by executing:

如果您没有Homebrew包管理器，您可以通过执行来安装它:

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

Now install gcc 4.9 by running:

现在通过运行安装gcc 4.9:

brew install gcc49

The GNU C++ compiler will now be available as g++-4.9.

GNU c++编译器现在可用作g++-4.9。

Next, a compatible version of the netcdf library will have to be installed (not the latest one). See this * question, or just download ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-cxx-4.2.tar.gz

接下来，必须安装netcdf库的兼容版本(而不是最新版本)。查看这个*问题，或者直接下载ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf/netcdf -cxx-4.2.tar.gz。

Once that version of netcdf has been extracted, cd into the output directory and run the following (note the CXX=g++-4.9 to build with that compiler instead of the default):

一旦netcdf的版本被提取出来，cd进入输出目录并运行如下(注意CXX=g++-4.9，以编译而不是默认编译):

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

Now back to rnnlib itself:

现在回到rnnlib本身:

You'll still need to apply some patches to get rnnlib to compile with g++-4.9 (but less patching than if you used Clang), as mentioned on this sourceforge thread.

您仍然需要使用一些补丁来使用g++-4.9(但是比使用Clang更少的补丁)来编译rnnlib，正如在这个sourceforge线程中所提到的那样。

The definition of the four range_min_size template functions need to be moved before they are first used in src/Helpers.hpp. A small patch is also needed to src/Container.hpp to call the resize() method as this->resize(). Here's the patch:

四个range_min_size模板函数的定义需要在src/Helpers.hpp中首次使用之前被移动。src/Container也需要一小块补丁。hpp调用resize()方法为->resize()。补丁:

Or download this patch from Github gist as it will be less error-prone: https://gist.github.com/0David/13d872c88172c75d4663

或者从Github的要点上下载这个补丁，因为它不会容易出错:https://gist.github.com/0David/13d872c88172c75d4663。

You can apply this by cd-ing into your rnnlib directory and running:

您可以将其应用到rnnlib目录中并运行:

patch -p1 < ../patch.txt

(replacing patch.txt with whatever you named the above patch file).

(替换补丁。txt与你命名的上面的补丁文件。

Now you'll have to run configure again specifying g++-4.9 (and so it will pick up the netcdf library we just built), and then make:

现在，您将不得不再次运行configure，指定g++-4.9(因此它将接收我们刚刚构建的netcdf库)，然后进行:

CXX=g++-4.9 ./configure
make

And you'll now have a working bin/rnnlib executable (which you can install with make install if you wish).

现在，您将拥有一个可工作的bin/rnnlib可执行文件(如果您愿意，可以安装它以进行安装)。

If you do need Clang, then this * question touches on the issue that's causing the compilation error that you show in the question, so src/Helpers.hpp will need to be updated to replace calls like t.get<0> with t.template get<0>, but there are further compilation problems beyond that, so it's easier just to build with GNU C++.

如果您确实需要Clang，那么这个*问题涉及到导致您在问题中显示的编译错误的问题，所以src/ helper。hpp需要更新，以替换t这样的调用。能与t < 0 >。模板得到<0>，但是除此之外还有更多的编译问题，所以用GNU c++来构建更容易。

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

You don't need to worry about that; malloc.h isn't a standard header file (malloc is declared in stdlib.h). See for example this * answer.

你不需要担心;malloc。h不是标准头文件(malloc在stdlib.h中声明)。例如这个*答案。
