X-SW-Source: 2004-07/txt/msg00495.txt.bz2 Hi, with our actual version of gcc (v3.2) we have problems with linking. It seems, that in the new version the problems are fixed. But with this version i cannot build ecos correctly. when linking the application, we will get multiple definitions ( e.g. icmpstat/cyc_icmpstat). It looks like, that this variables are multidefined because of declarations in header files (e.g. icmp_var.h) Now we are changing Ecos Source Code. Are there more problems, we have to expect? Wo have already a eCos version prepared for gcc 3.4.1 Regards Richard -----Original Message----- From: ecos-discuss-owner@ecos.sourceware.org [mailto:ecos-discuss-owner@ecos.sourceware.org]On Behalf Of fredrik@wespot.com Sent: Donnerstag, 29.

Faster, slower, buggier, better ? GCC 3.4.x has a much faster implementation of floating point operations. If you are using alot of float and double, you can get much faster code. I'm using GCC-3.4.1, binutils-2.14, newlib-1.12.0, gdb/insight-5.3 and it works really great. The code gets some kilobytes larger with GCC 3.4.x than with GCC 3.3.x though. We are not using binutils-2.15 since I have experienced bugs in arm-elf-objdump. We simply cannot disassemble our elf-file. We are not using GDB-6.1.1 since I experienced that our eCos stubs uses an obsolete register setup. GDB-5.3 works fine. Maybe this is fixed in eCos HEAD, we are using the 2.0 release.
