Hi,

I am trying to compile C++ with R and I am coming up against - what I
believe - is a linker configuration issue.

For example, using has_develop() gives the following message...

> has_devel()
"C:/PROGRA~1/R/R-30~1.2/bin/i386/R" --vanilla CMD SHLIB foo.c
gcc -m32 -I"C:/PROGRA~1/R/R-30~1.2/include" -DNDEBUG
-I"d:/RCompile/CRANpkg/extralibs64/local/include"     -O3 -Wall  -std=gnu99
-mtune=core2 -c foo.c -o foo.o
gcc -m32 -shared -s -static-libgcc -o foo.dll tmp.def foo.o
-Ld:/RCompile/CRANpkg/extralibs64/local/lib/i386
-Ld:/RCompile/CRANpkg/extralibs64/local/lib
-LC:/PROGRA~1/R/R-30~1.2/bin/i386 -lR
collect2: ld returned 9 exit status
Error in inDL(x, as.logical(local), as.logical(now), ...) :
  unable to load shared object 'C:/TEMP/Rtmpes5hJL/foo.dll':
  LoadLibrary failure:  The specified module could not be found.

 I am running Windows 7 (32-bit), Rtools has been installed and is in my
path (i.e. I can run gcc/g++). The object file (.o) gets created but then
the linking goes awry.

Another thing here is that I do not know where the directory RCompile is as
it appears to be trying to link some 64-bit stuff (i.e. extralibs64).

Any help/thoughts would be fantastic,

Sam
