    Not really hard to fix but hard to understand. why it's prevent warning,
    it cause errors :)


I succeed to compile all module and to build libgsl.lib. but now when
i try to link i have this error:


Turbo Incremental Link 5.00 Copyright (c) 1997, 2000 Borland
Error: Unresolved external '_gsl_sf_lngamma' referenced from C:\LIBGSL.LIB|gamma
Error: Unresolved external '_gsl_sf_choose' referenced from C:\LIBGSL.LIB|binomial
Error: Unresolved external '_gsl_sf_lnfact' referenced from C:\LIBGSL.LIB|poisson


i don't know for this time what it means, any ideas?

Thanks for the bug reports.  I have made the line into a macro
DISCARD_POINTER(p) which can be redefined in config.h.

The functions the randist directory (libgslrandist.a) need to use some
functions from the specfunc directory, and cannot find them.  Perhaps
it is due to the order of linking the files?

I didnt'know that the linking part of the process need an order when i
add the obj files to the lib. I'll try this(i think that it's write in
the makefile) .

In fact i compile the files into obj. All compile good now. The next
step is to make a lib. How to do it, because the above pb is in fact
due that in the dir structure
root/
     >specfunc
     >randist
These two dirs have a file gamma.obj. When i try to add one to the
archive(lib) it's good but when i try to add the second i think that
there are problem of references because two files have the same name
in the lib. Do you think that it is pb? How to deal with it. I have
all obj files produced with borland C++ builder, no severe error and i
can't produce the lib.

Another little question how to export all functions to make a dll.
(in fact i try to use(with some modif,coff2omf,impdef,...)  the dll provided with the gsl-bin0.0.zip file
but some functions always don't work( i have a exception about the
fact that the memory is read....). Does anyone alreadu heard about
this.

With MSVC++ I was able to link object files from separate directories.
i.e.  it would allow linking of dir1/file.obj and dir2/file.obj into
the same library if the directories were different.

If that does not work maybe you'd have to rename one of the files?
Unfortunately there are many other files with the same names,
e.g. 'init.o', 'oper.o' etc in several directories.  So that probably
would not work either.  Sorry I cannot help more... my knowledge of
this subject is limited.

DLL's are a mystery to me... if someone can explain how to make them I
would also be interested!  I have only managed to make .lib files so
far.
