I'm begining to work with djgpp and I have a question about DLL=B4s.
I've installed the djgpp basic package and the rsxntdj package. I can
compile c programs and then link them in a exe file. But when I try to
execute it I've got this error:

                SIGSEGV

I've found that it is a problem with the libraries. I read that the
linker (ld.exe) supplied with RSXNTDJ doesn't print any messages if some
of the functions are missing at link time.
For that reason I use the DJGPP's version of ld.exe to link the program,
and look up every function about which the linker complains as being
``unresolved'' or ``undefined''.
I've found that these functions are in DLL`s, but I don't know how to
link a dll.

I try to convert a DLL to a library with the function makelib, but I
can't because the makelib always put  \\ before the name of the library
I want to create and in windows 95 it is an error.
Exemple:
                    makelib odbc32.dll
                    Error: Can=B4t create c:\windows\system\\odbc32.a

This is the problem

Please, can anyone help me with this problem??

Thank you in advanced.
