Hi, ALL: After built Linux kernel 2.2.12 for mips r3000, I got the related files for glibc-2.0.6 build. But I found a problem when I were building glibc 2.0.6. Here is part of the screen printout: cd build <return> C=mips-linux-gcc BUILD_CC=gcc AR=mips-linux-ar RANLIB=mips-linux-ranlib ../configure --prefix=/usr --host=mips-linux --enable-add-ons=crypt,linuxthreads,localedata --enable-profile <return> ..... ...... checking installed Linux kernel header files... TOO OLD! configure: error: GNU libc requires kernel header files from Linux 2.0.10 or later to be installed before configuring. The kernel header files are found usually in /usr/include/asm and /usr/include/linux; make sure these directories use files from Linux 2.0.10 or later. This check uses <linux/version.h>, so make sure that file was built correctly when installing the kernel header files. It seems that I need to copy the kernel's include files and lib to somewhere. I could not figure it out. If you know how to build the glibc, please let me know. Thank you all. Steven Liu
