Hi Igor, thanks for forwarding the report. Unfortunately, Konstantinos is not right in his statement. I don't know how he measured "on most other platforms", but the flags is necessary for the following reasons: there are many important platforms (for OpenAxiom) that are bi-arch, e.g. can run both 32-bit and 64-bit programs. Solaris, and earlier versions of Mac OS X, Windows 7 on 64-bit archi, and certain linux distros come to mind. On these systems the available Lisp system may be built with a certain CPU precision that is not the default of the C++ compiler. For example, on Windows 7 (and Mac OS X notably), the Lisp system may be built as a 32-bit application (think SBCL), whereas the C++ compiler defaults to 64-bit; or the Lisp system may be built as 64-bit application (think CCL) whereas the C++ compiler defaults to 32-bit. Since we link part of the C++ libraries into the Lisp image, we do need to have both components built with the same CPU precision. Consequently, we can't just drop the -m flags. What might makes sense to do is to test at configure time whether the available compiler understands the flags. Unfortunately, I do not have access to the machine that is causing trouble for Konstantinos. Is he or you willing to test a patch and report? -- Gaby ------------------------------------------------------------------------------ How fast is your code? 3 out of 4 devs don\\\'t know how their code performs in production.
