Hi all, Greg, i finally have the toolchain created, had to go over the 2 follwing issues: 1) as you pointed out, uclibc headers install path was not correct, had to modify manually uClibc.X.X/.config with the correct RUNTIME_PREFIX= DEVEL_PREFIX= under include, i have now all libc includes. 2) compilation was still breaking on checking whether to use setjmp/longjmp exceptions... unknown configure: error: unable to detect exception model I replaced binutils 2.26 with 2.25, all worked fine. ------------------------------------------------------------ Btw, using the new generated toolchain to compile a c++ app, i still get same error i had with older uclinux toolchians: src/manager.cc:88:15: error: ‘usleep’ was not declared in this scope usleep(10000); ^ makefile:37: set di istruzioni per l'obiettivo "obj/manager.o" non riuscito make: *** [obj/irc_manager.o] Errore 1 Thomas, many thanks, will try buildroot in case.

At the time being, with the toolchain m68k-uclinux-20101118 i get some errors, like usleep not declared, even including <unistd.h>, as 88:15: error: ‘usleep’ was not declared in this scope Actually, the only toolchain i can use successfully for c++ apps on mcf5307 is an old Sourcery_CodeBench_Lite_for_ColdFire_uClinux But we know they are no more available / open. Do you know any other alternative ? Or a guide i can use to prepare a c,c++ toolchain for uClinux (then i can make it available) ?You can also try to build a Coldfire toolchain with Buildroot. We have some minimal m68k support, but the uClibc-ng maintainer is very reactive and will very likely help if you report some issues. And using Buildroot, you will not only be able to build the toolchain, but also a complete Linux system. Best regards, Thomas |
