使用rJava LoadLibrary"无效的win32应用程序"失败构建R包失败

Question

我写了一个R包来连接R和messageQueues,特别是activeMQ和rabbitMQ,所以所有的源都可以在这里找到:http://r-forge.r-project.org/projects/r-message-queue/

r-forge无法构建软件包,因此我在本地重新创建/调试,但我的本地构建在此过程中早于r-forge失败.

我正在运行64位windows7,64bit R v2.15.2.
如果我以错误的方式解决这个问题,请告诉我.

建立R包

$ R --verbose CMD build messageQueue
* checking for file 'messageQueue/DESCRIPTION' ... OK
* preparing 'messageQueue':
* checking DESCRIPTION meta-information ... OK
* checking for LF line-endings in source and make files
* checking for empty or unneeded directories
* building 'messageQueue_0.1.tar.gz'
cygwin warning:
  MS-DOS style path detected: C:/Users/msm336/workspace_r/messageQueue_0.1.tar.gz
  Preferred POSIX equivalent is: /cygdrive/c/Users/msm336/workspace_r/messageQueue_0.1.tar.gz
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:

检查R包

$ R --verbose CMD check messageQueue_0.1.tar.gz
* using log directory 'C:/Users/msm336/workspace_r/messageQueue.Rcheck'
* using R version 2.15.2 (2012-10-26)

* checking package namespace information ... OK

当我在Windows7 x64上使用64位版本的java运行x64 R时,我不确定为什么要尝试加载i786版本的rJava:

$ java -version
java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b22)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)

我的路径上也有JAVA_HOME/jre/bin/server/jvm.dll,因为rJava不知何故喜欢它.

任何帮助将不胜感激.

谢谢,

马特.

默认情况下,R的检查功能将尝试针对所有相关体系结构测试包.在windows7 x64机器上,这意味着它将尝试针对i386和x64测试软件包.

不幸的是,当使用x64 JDK运行R x64时,它似乎无法干净地管理体系结构依赖关系,因此尝试在x64上下文中加载i386 DLL(/rJava/libs/i386/rJava.dll)并失败.我不完全理解为什么,但可以解决它.

可以使用--no-multiarch开关强制执行R CMD检查messageQueue以针对当前(默认)体系结构运行.它在Writing R Extensions手册的1.3.1节中有记录(参见:附近的多个子架构).

我更新的R命令只检查当前架构:

R --verbose CMD check --no-multiarch messageQueue_0.1.tar.gz

真棒.
