by Hello,
I carefully followed the ELF-HOWTO instructions for building an ELF
bootstrap development system. I am using Slackware 2.2, Linux 1.2.4,
and gcc 2.6.3 (not 2.6.2 as described in the HOWTO). However, I have
not managed to compile libc correctly and was hoping someone could
help me out.
Binutils 2.5.2.6 and an ELF version of gcc-2.6.3 compiled
correctly. Minor problems were encountered in the bfd subdirectory of
binutils when configure.in did not substitute some variables
correctly.
When building libc, I received the errors listed below. Can
someone tell me why this library isn't linking correctly? Do the
standard library symbols need to be weak? I fiddled randomly for some
time, to no avail.
Thanks!
Philippe McLean
