linuxers,
<br>
<br>
<br>
I am trying to compile glibc2.9 on Ubuntu 7.10
<br>
and I am experiencing chicken and egg problem :
<br>
<br>
Here the steps I do
<br>
<br>
1. ../glibc-2-.9/configure
<br>
<br>
2. make
<br>
<br>
Result:
<br>
dl-load.c:1796: more undefined references to `__stack_chk_fail_local'
follow
<br>
collect2: ld returned 1 exit status
<br>
<br>
Google search reveals that this function belong to stack-protector
feature and advised to turn it off
<br>
So I removed buid directory to start again
<br>
<br>
1 . export CFLAGS="-fno-stack-protector"
<br>
export CXXFLAGS="-fno-stack-protector "
<br>
<br>
<br>
2. ../glibc-2-.9/configure
<br>
<br>
3. make
<br>
<br>
Result
<br>
glibc-build/config.h:3:3: error: #error "glibc cannot be compiled
without optimization"
<br>
<br>
Can smb advise on this ?
<br>

You overrode the default CFLAGS, CXXFLAGS with your own version - which
does not include -O<br>
Add -O2 to your CFLAGS, CXXFLAGS. Possibly other flags are needs as
well. See which flags are used by default.<br>
