Hi, i have recently compiled with success the atlas library with cygwin under
winxp (cblas library only, not fortran).
I have tested that everything is working with (in cygwin):
gcc -I/cygdrive/c/ATLAS/include -L/cygdrive/c/ATLAS/lib/evon1015v testblas.c -o
testblas -lcblas -latlas
Problem is that now i need to test the program with digital mars c++ and i have
problem with the idde's project settings.
I inserted the "include" and "lib" directorys in the directory tab, but i don't
know how to pass the "-lcblas -latlas" option to the compiler.
I hope it's possibile to compile a library with gcc and link it with dmc, as
otherwise i won't be able to use dmc for numerical computing, where dmc's speed
is really needed.
Thank you in advance for your reply

Greetings
Stefano

Click right on the project in the project tree.
click on "Edit project..."
set the "list files of type:" to "Library (*.lib)"
type the name.ext of the lib in the field "File Name"
click on button "Add"
repeat for all libs
click on button "Ok"
link

When the lib dir is correct the libs will be found and linked in.

Should be when the lib (interface) is in C and the correct calling convention is used.

When the lib (interface) is C++ forget it.

Having compiled the atlas library with gcc under cygwin i got two library:
libclbas.a and libatlas.a (and header cblas.h)
If i try to rename them to .lib and add them to the project as you suggested i
get:
"Not a valid library file" when i try to build the project.
If i don't i get the myssing symbols errors.
With gcc (and the associated syntax illustrated previously) i get no error, why?
Also, my final goal is to able to use IT++ (see itpp.sourceforge.net) with dmc,
after having compiled succesfully atlas and lapack with gcc on cygwin (alredy
done this step).
Thank you for your reply

If I remeber correctly Cygwin/Mingw generate COFF libraries and DM use OMF ones.
Try coff2omf from DM CD or better try to compile the library with DM compiler itself.
Other option is to generate a dll with cygwin and use it.

Todor

I made a quick google search, seems true.

I used coff2omf and it converted the librabries. Now i don't get the lib error message, but the following warnings followed by the error (read also below....):

****************************************

Problem is that the altas lib come with a make script incompatible with dmc (it
is for gcc), and i don't know how to hack it to be able to compile the library
wth dmc. Do you have any suggestion/tutorial about this topic?
Same is true with clapack and IT++.
Also i think it's best to compile altas with gcc, as it's code has been
optimized for it (you should also use very specific version of gcc to avoid
performance penalty).

>Other option is to generate a dll with cygwin and use it. Regards,
Is it possibile to do so from the already built library?
Or do i have to hack the make file?
Thank you!

I solved the problem, finally!
The problem was that i was mixing 16bit with 32bit code becouse i selected dos
and not winNT as platform.
Thank you again for you help pointing me to coff2omf that solved all my problem.
