I have successfully created a DLL using the example makefile on Fergus
Henderson's web pages that I found from previous posts to this list. I
needed to add the library libf2c.a to the list of libraries because there
is a Fortran program in the library, and this worked fine for compiling.
I linked to the libfoo_dll.a (in my case, prntfor_dll.a) file created by
the makefile, as the web page recommends. However, when I try to call the
DLL from a Windows application (called Map Info), I get the following
message:
"Unable to load prntfor_dll.a because it is not a 32-bit library."
Has anyone ever seen this before, or have any suggestions as to what might
be wrong? Here are some more details that might be relevant...
- I'm working on an NT PC
- Using another set of instructions on the web for building DLLs with
Gnu-Win32, I have previously gotten other messages about Map Info simply
not being able to read the library at all. Using Fergus Henderson's
Makefile, I got the "32-bit" message, which is at least a little more
informative.
- I've already tried the web page suggestions of setting RELOCATABLE to
"yes" and `LDFLAGS-libfoo = --image-base=0x0800000 (within the makefile),
and these did not change the error message.
- The contents of the DLL, for testing purposes, is a simple fortran
program that opens a file and writes to it.
Thanks
