Question

我需要在项目中使用R包Rglpk并需要修改包 - 特别是，我需要在界面中添加一个时间限制控制参数选项（它是GLPK v4.5.2本身的一个选项，但是Rglpk 0.5-2不支持此参数）。这将允许R呼叫GLPK并将搜索时间限制为用户指定（即搜索时间＆lt; = t）。

我修改了Rglpk代码，并在Mac OS X v10.9.2上成功编译了软件包，并验证它是否按预期工作。我的项目需要在Windows上运行，我无法在Windows上编译修改后的Rglpk软件包，或者未经修改的软件包（Rglpk 0.5-2）。我尝试将原始包上传到Win Builder（http://win-builder.r-project.org/），但我收到了同样的错误。

以下是我在Windows 7（我的机器）上所做的总结：

（1）从http://cran.r-project.org/web/packages/Rglpk/index.html下载Rglpk 0.5-2包源（2）将文件解压缩到目录。所有代码都在一个名为Rglpk的目录中。（3）启动RStudio v0.98.490。我安装了devtools v1.4.1，安装了Rtools v3.1，以及R v3.0.2 （4）打开一个新项目并选择（2）中提到的Rglpk目录。（5）在“Build”菜单下，选择“Build and Reload”。结果是包编译并加载：

** R
** inst
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
* DONE (Rglpk)

（6）在“Build”菜单下，选择“Check Package”。结果是安装失败。日志文件如下所示。

我曾尝试编译另一个包含C代码并且无法编译它的软件包。我试图编译的包是devtools v1.5在这种情况下返回的错误是'LoadLibrary失败：％1不是有效的Win32应用程序。'

有没有人在Windows上编译包含C代码的R包的经验？我已经能够编译只涉及R代码的包，但似乎C代码很麻烦。

任何帮助都将不胜感激。

Answer 1

看起来有些事情出错：

目标文件已预先编译，但未清除。
因为这些目标文件是预编译的，看起来它们是为64位体系结构编译的，所以当你尝试在32位构建中使用它们时，安装过程barfs。

这里的修复将删除所有这些*.o文件（它们需要编译为R CMD build步骤的一部分，我想），然后生成的tarball可以是{{ 1}}编

您应该考虑安装更新版本的RStudio和devtools，并确保使用devtools来处理构建过程 - 它可能能够帮助您。
