问题描述
我正在编写一个包含Fortran源代码的R包。总之，我的问题是当我尝试安装软件包时，出现错误gfortran -m32：not found，但是，当我不安装软件包时，我可以使用gfortran -m32编译我的代码。
I am writing an R package that has Fortran source code. In short, my problem is when I try to install the package I get the error "gfortran -m32: not found" however, I am able compile my code using gfortran -m32 when I'm not installing the package.
详细版本：
我已经安装了最新版本的R（3.1.1）以及最新版本的Rtools （C：\Rtools\bin; C：\ Rtools \ gcc-4.6.3 \ bin; C：\ Program Files \R\R-3.1.1） \bin\x64; C：\ msys; C：\程序文件（x86）\ SSH安全Shell; C：\程序文件\MiKTeX 2.9\miktex\bin）。
I have installed the newest version of R(3.1.1) along with the newest version of Rtools(31) and renamed my path variables accordingly (C:\Rtools\bin;C:\Rtools\gcc-4.6.3\bin;C:\Program Files\R\R-3.1.1\bin\x64;C:\msys;C:\Program Files (x86)\SSH Secure Shell;C:\Program Files\MiKTeX 2.9\miktex\bin).
出于测试目的，我从包含Fortran源代码的CRAN下载了PropClust软件包。
For testing purposes, I downloaded the PropClust package from CRAN which has Fortran source code.
当我在构建它之后键入R CMD INSTALL PropClust_1.4.tar.gz时，出现以下错误：
When I type "R CMD INSTALL PropClust_1.4.tar.gz" after building it, I get the following error:
* installing *source* package 'PropClust' ...

虽然它说gfortran -m32：not found我已经在同一个窗口中编译了相同的选项（gfortran -m32 -O3 -mtne = core2 -c a.f90 -o a.out）没有问题。有没有人有过这个问题？我正在运行Windows 7 64位，如果这很重要的话。
Although it says "gfortran -m32: not found" I have compiled my code in the same window with the same options(gfortran -m32 -O3 -mtne=core2 -c a.f90 -o a.out) with no problems. Has anyone had this problem before? I am running Windows 7 64-bit if that matters.
推荐答案
我有类似的问题： R 正在调用 gfortran-4.8 - 在我的系统上无法识别的命令 - 而不是 gfortran 。在我的主目录中创建文件〜/ .R / Makevars 时，此问题已得到解决。这里是 Makevars 的内容，它指向相应的 gfortran 安装：
I had a similar problem : R was invoking gfortran-4.8 - an unrecognized command on my system - instead of gfortran. This problem was fixed upon creating the file ~/.R/Makevars within my home directory. Here are the contents of Makevars which points to the appropriate gfortran installation:
F77 = gfortran
FC = gfortran
FLIBS = -L/usr/local/gfortran/lib
