Do you really mean you had to build with "static" *before* "dynamic"? weird ... I think that while it's under development, maybe a static library would be the Right Thing.

Yes, building "static" puts an archive (.a) in the expected place (../lib/), where a subsequent "dynamic" build apparently uses it. > I think that while it's under development, maybe a static library > would be the Right Thing. Maybe, as -g is in use. On a related note, the project builds and runs correctly on Ubuntu 10.04 using GNAT 4.4.3 (FSF), Mercurial 1.4.3, blas 1.2, and lapack 3.2.1. -- John B.

I've made a static release (20100801, delay caused by SF file release system outage) at http://sourceforge.net/projects/gnat-math-extn/files/ > On a related note, the project builds and runs correctly on Ubuntu 10.04 > using GNAT 4.4.3 (FSF), Mercurial 1.4.3, blas 1.2, and lapack 3.2.1. Good news.

I have just run the 20100801 release on my Windows machine and everything seems fine. I did everything on the command line. YC |
