Hello:
I followed the directions in techtip 3798 ("Using CALL_EXTERNAL with
the Cygwin environment"). I needed to make one change in the
directions; I changed the reference in the tech tip directions from
IDL61 to IDL62se to reflect the fact that I have a student edition of
IDL (in the redefinition of !make_dll.cc).
On attempting to run the examples of C inclusions into IDL, I get the
following output. I get similar issues when trying to compile other C
code as well (ie, Could Not Find errors for .lib, .exp, and .obj
files). I believe that this might be a configuration
issue....somewhere..., but I am not sure where and google has not
proven to be my friend with finding references to the same issue
elsewhere. Has anyone else encountered this problem before and know of
a solution? (And are .lib, .exp, and .obj files an IDLism? From the
default C compiler in windows IDL? From the phase of the moon?)
I have access to the full version of IDL as well, if someone thinks
that is the problem; however, the IDL student edition is the only
version in which I installed all the necessary files.
Thanks for any insights!
