Hi there,
I'm trying to load some f77 code by building a DLL and then using
dll.load() on S+2000 under Win98 (as some tech-support people suggested
earlier on this list).
I've downloaded the last version of mingw32/gcc (2.95) and everything
seems to work fine.
In order to build the .dll file I follow some instructions in the
"ftp://.../gnu-win32/mingw32/misc/README.dllhelpers" file.
Specifically on the MS-DOS prompt I type:
g77 -c -g -o mys.o mystuff.f
dlltool --export-all --output-def mys.def mys.o
dlltool --dllname mys.dll --def mys.def --output-lib mys.a
dllwrap --driver-name g77 --def mys.def -o mys.dll mys.o mys.a
then, on S+2000/Win98 I type
> dll.load("[path]/mys.dll")
[1] 1
> .Fortran('mystuff',...)
Error in .Fortran("mystuff",: "MYSTUFF" is not a symbol in the load
tabl
and the reason seems to be that the file "mys.dll" doesn't have any
symbol, as shown by
> dll.load.info("c:[path]\\mys.dll")
$"c:[path]\\mys.dll":
character(0)
Does anybody have any experience on using this port of gcc to do this?
Am I missing something? Am I completely off? Any help, pointer, hint or
comment will be greatly appreciated! If it's of any interest to the
rest of the list I'll post a summary of the replies I get.
