I use the arm-linux toolchain for 2.6 uClinux development. > I tried to download the Snapgear's arm-linux toolchain, and found the C lib > of the toolchain is glibc instead of uclibc. > Is it suitable for uclinux world? Yes. A build of uClinux-dist doesn't use the libc from the toolchain. If you want to build c++ apps then that is a different story. > Will it make the userland program size too large? No, glibc in the toolchain is not used to generate user applications in uClinux-dist builds. > Shouldn't the uclinux use the uclibc based toolchain? Only if you need it to be able to build stand alone apps outside of the uClinux-dist build framework. > By the way, should i use the "linux-2.6.24-uc0.patch" from uclinux as my > kernel porting start point? > Or use the "linux-2.6.14-hsc0.patch" from the uClinux/ARM2.6 > project(http://opensrc.sec.samsung.com/)? > In fact, the two projects confuse me. Up to you :-) 2.6.14-hsc0 is old and won't port to newer kernels easily. But many of the mmu-less targets had some working support. 2.6.24-uc0 is a modern kernel version, and large parts of it merged into mainline linux 2.6.24. But some of the non-mmu arm target CPU's code is not up to date for it.
