Dear all, I have problems loading a library in the 64 version of R. The following happens: ? I have a file, equildistC.cpp, which contains a few lines of C++ code. ? I have compiled the file using the following commands: PATH = c:\Rtools\bin;C:\Rtools\gcc-4.6.3\bin;C:\Rtools\gcc-4.6.3\bin64;C:\Rtools\gcc-4.6.3\i686-w64-mingw32;C:\R-2.15.1\bin\i386;C:\R-2.15.1\bin\x64;c:\windows;c:\windows\system32;C:\Windows\SysWOW64 R --arch x64 CMD SHLIB equildistC.cpp
That runs the 32 bit version of R (since you list it first in your path). I don't see any docs that state that it will pay attention to the --arch directive. (The docs say that syntax is supported under Unix-alikes, not under Windows.)
? I have received no messages indicating problem during compilation, and both the equildistC.o and the equildistC.dll have been created.
? When I load the dll in the 32bit version of R with dyn.load("C:\\Ccodefortransortmodel\\equildistC.dll"), things appear to go well.
? However, in the 64 bit version, I get the message:
Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared object 'C:/Ccodefortransortmodel/equildistC.dll':
LoadLibrary failure: %1 is not a valid Win32 application.
I have googled the error message. Initially I had omitted ?--arch x64? when compiling the file, but even after specifying the architecture, the error persists.
However, I definitely need to be able to run my code on the 64 version.
Then you should take the 32 bit version out of your path. Duncan Murdoch
Kind regards Laurent
