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
· 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.
Kind regards
Laurent
