Description antonprk 2009-12-04 06:45:14 UTC 
2.6.31 - 2.6.32 fails to compile with gcc 3.4.6 . The same
config however compiles with 
Reading specs from /usr/lib/gcc/x86_64-redhat-linux/3.4.6/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=x86_64-redhat-linux
Thread model: posix
gcc version 3.4.6 20060404 (Red Hat 3.4.6-11)

CentOS release 4.8 (Final)

# CONFIG_PARAVIRT_GUEST is not set
CONFIG_PARAVIRT=y
# CONFIG_PARAVIRT_DEBUG is not set


I have successfully compiled 2.6.2{7,8,9}.x and 2.6.30.x kernels with gcc 3.4.6 before.
