[odb-users] Building ODB compiler on Centos 6.7

[Andrew Cunningham]

I  need to build the ODB compiler on CentOS 6.7 to get a patched 2.4.0 (
Thanks Boris!!)

However, the GCC on CentOS 6.7 does not support plugins.
So I downloaded and installed "Scientific Linux" developer package of GCC
4.8.2 and switched to that as the default compiler.

gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/home/opt/rh/devtoolset-2/root/usr/bin/../libexec/gcc/x86_64-redhat-linux/4.8.2/lto-wrapper
Target: x86_64-redhat-linux
Configured with: ../configure --prefix=/opt/rh/devtoolset-2/root/usr

Thread model: posix
gcc version 4.8.2 20140120 (Red Hat 4.8.2-15) (GCC)


However,
./configure still fails....
./configure
checking whether the g++ linker
(/home/opt/rh/devtoolset-2/root/usr/libexec/gcc/x86_64-redhat-linux/4.8.2/ld
-m elf_x86_64) supports shared libraries... yes
checking dynamic linker characteristics... (cached) GNU/Linux ld.so
checking how to hardcode library paths into programs... immediate
configure: creating ./config.lt
config.lt: creating libtool
checking whether g++ supports plugins... no
configure: error: g++ does not support plugins; reconfigure GCC with
--enable-plugin

Any ideas.
