as an experiment, i want to create an updated version of a Nios II toolchain, and i thought i'd start with testing whether i could just compile the latest version of uclibc with the older toolchain, and take it from there.
first, i already have a nios2 cross-compiler toolchain from here: http://nioswiki.jot.com/WikiHome/OperatingSystems/%C2%B5Clinux/BinaryToolchain that toolchain is based on gcc-3.4.6 so, as a first exercise, i thought it would be educational to see if i could cross-compile the latest svn checkout of uclibc with it. the toolchain has the following contents in "lib": -rw-r--r-- 1 rpjday rpjday 1508 2006-05-07 09:54 crt1.o -rw-r--r-- 1 rpjday rpjday 1069 2006-05-07 09:54 crti.o -rw-r--r-- 1 rpjday rpjday 1075 2006-05-07 09:54 crtn.o -rw-r--r-- 1 rpjday rpjday 5544 2006-05-07 09:57 elf2flt.ld drwxr-xr-x 3 rpjday rpjday 4096 2006-05-07 09:53 gcc drwxr-xr-x 2 rpjday rpjday 4096 2006-05-07 09:50 ldscripts -rw-r--r-- 1 rpjday rpjday 994734 2006-05-07 09:54 libc.a -rw-r--r-- 1 rpjday rpjday 13038 2006-05-07 09:54 libcrypt.a -rw-r--r-- 1 rpjday rpjday 796072 2006-05-07 09:57 libiberty.a -rw-r--r-- 1 rpjday rpjday 204618 2006-05-07 09:54 libm.a -rw-r--r-- 1 rpjday rpjday 772 2006-05-07 09:54 libnsl.a -rw-r--r-- 1 rpjday rpjday 100344 2006-05-07 09:54 libpthread.a -rw-r--r-- 1 rpjday rpjday 778 2006-05-07 09:54 libresolv.a -rw-r--r-- 1 rpjday rpjday 9964 2006-05-07 09:54 librt.a -rw-r--r-- 1 rpjday rpjday 35600 2006-05-07 09:54 libthread_db.a -rw-r--r-- 1 rpjday rpjday 5592 2006-05-07 09:54 libutil.a now, if i configure uclibc fairly minimally (static flat target file format, no POSIX threading, no math lib, etc.), i can in fact get a successful build, with the following contents in the new "lib" directory: -rw-rw-r-- 1 rpjday rpjday 1564 2007-10-18 08:29 crt1.o -rw-rw-r-- 1 rpjday rpjday 956 2007-10-18 08:29 crti.o -rw-rw-r-- 1 rpjday rpjday 920 2007-10-18 08:29 crtn.o -rw-rw-r-- 1 rpjday rpjday 746674 2007-10-18 08:29 libc.a -rw-rw-r-- 1 rpjday rpjday 12602 2007-10-18 08:27 libcrypt.a -rw-rw-r-- 1 rpjday rpjday 79142 2007-10-18 08:28 libm.a -rw-rw-r-- 1 rpjday rpjday 772 2007-10-18 08:28 libnsl.a -rw-rw-r-- 1 rpjday rpjday 778 2007-10-18 08:28 libresolv.a -rw-rw-r-- 1 rpjday rpjday 9744 2007-10-18 08:28 librt.a -rw-rw-r-- 1 rpjday rpjday 5688 2007-10-18 08:28 libutil.a so it's a subset of the above, but it at least built. at this point, my plan would be to start adding features to the configuration, seeing which ones break and seeing if i could fix them. is this a sane way to start the process -- just to see where the older toolchain has problems building the current version of uclibc, and seeing if there's an obvious fix? thanks. rday -- ======================================================================== Robert P.
