[Mingw-users] adding my own libraries to mingw

[William S. <wil...@gm...>]

Thanks again very much for the previous help. I am a scientist, not a
programmer, and I know enough to get my scientific tasks done
(presenting precisely controlled visual stimulus displays, sending
triggers over the parallel port, and reading the serial port).

I am trying to migrate from djgpp (a species of gnu c compiler) under
DOS to mingw under Windows XP. Sorry for my questions. I really have
looked and it is difficult to find the info I need.

From:

http://www.mingw.org/wiki/IncludePathHOWTO
http://www.mingw.org/wiki/SpecsFileHOWTO

it seems I have a few options.

Under djgpp I did as follows, for a library I wrote called rand. I
have djgpp\lib\src\rand\rand.c
I have the source rand.c, the header rand.h, and the makefile there.
In the makefile I have
rand:   rand.c
       gcc -c rand.c
       ar rvs librand.a rand.o
       del rand.o
       move librand.a \djgpp\lib
       copy rand.h \djgpp\include

Then subsequently I put #include "rand" at the top of any program that
uses it and put -lrand in my makefile when I compile it.

First, I think that for mingw I need to put a "\" at the ends of the
lines like so:
rand:   rand.c
       gcc -c rand.c \
       ar rvs librand.a rand.o \
       del rand.o \
       move librand.a \djgpp\lib \
       copy rand.h \djgpp\include

By analogy, maybe in mingw I would do:
       move librand.a c:\mingw\lib \
       copy rand.h c:mingw\include

I am not at all sure about:
       ar rvs librand.a rand.o \


>From what I read, one possibility is to stick the libraries in
c:\mingw\local
or maybe c:\mingw\local\lib ?
This seems nice, because it keeps my libraries separate from mingw's.
Would mingw be smart enough to know to look there? Otherwise I guess I
would need to set LIBRARY_PATH? How?

How about the header files? Where do they go?
c:\mingw\local
c:\mingw\local\include ?
Would mingw be smart enough to know to look there? Maybe there's an
INCLUDE_PATH?

Fiddling with Specs seems an option too, but it is too sketchy for me
to figure out.

Any tips appreciated!!

Thanks very much
