Hi Mark! Mark H Weaver m...@netris.org writes: l...@gnu.org (Ludovic Courtès) writes: OK. I was thinking that I’d use C when dealing with fixnums or floats, and let Guile manage bignums and similar—in which case writing C doesn’t seem to help much. Do you think there are use cases

Re: [PATCH] Fix the R6RS exact-integer-sqrt and import into core guile

Hi! Mark H Weaver m...@netris.org writes: exact-integer-sqrt is broken. It is now implemented in (rnrs base) by doing an inexact sqrt and coercing the answer to exact. This fails badly for large integers: scheme@(guile-user) (use-modules ((rnrs base) #:version (6)))

Re: Guile with win32 cross compiling

Hello, Volker Grabsch v...@notjusthosting.com writes: If I understand this correctly, the proposed way for cross compilation is to build the code generators (like gen-scmconfig) entirely using the build toolchain. This means that uniconv.h and others have to be available on the build system,
