Hi Jim,
the problem here is, that the fortran 77 bindings are not ready for
being compiled to a dll with Visual C++. You can read former posts about
that (regarding "DLL hell").
It works though with MinGW (therefor I works for me), since MinGW
exports all symbols.
To explain the problem in short: Visual C++ exports by default no
function to a dll, which has not a special keyword in front of it
(__declspec(export) or similar). Since no function in the f77 bindings
has this keyword in front, no functions get exported.
As a short workaround (until we made the bindings ready for "dll hell")
change line 70 in plplot/bindings/f77/CMakeLists.txt to
add_library(plplotf77c${LIB_TAG} static ${plplotf77c${LIB_TAG}_LIB_SRCS})
(add the word static). Then the f77 library will always be build as
static and you shouldn't have any more problems for the moment. I'll try
to change the code soon.
HTH,
Werner
