[LLVMdev] llvm-2.2 cannot be successfully built with 'make ENABLE_OPTIMIZED=1'

[AndrewWu]

My platform is RedHat Enterprise 5, as shown below:

         [wuxi at ppidellsc1420 lib]$ uname -a

Linux ppidellsc1420 2.6.18-8.el5 #1 SMP Fri Jan 26 14:15:21 EST 2007 i686
i686 i386 GNU/Linux

 

and I install gcc-4.2.3, as shown below:

         [wuxi at ppidellsc1420 lib]$ g++ -v

Using built-in specs.

Target: i686-pc-linux-gnu

Configured with: ../gcc-4.2.3/configure --prefix=/home/wuxi/gcc-4.2-install/

Thread model: posix

gcc version 4.2.3

 

I follow the command:

         CXX=PATH_TO_MY_G++ ../llvm/configure -prefix=/usr/local

To configure llvm

 

And next when I use 'make ENABLE_OPTIMIZED=0', it can successfully build
llvm, with the warning that I may get 10 times slower.

 

But when I use 'make ENABLE_OPTMIZED=1', the compilation fails with the
message:

         /home/wuxi/llvm-2.2/llvm-objects-opt/Release/bin/tblgen:
/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by
/home/wuxi/llvm-2.2/llvm-objects-opt/Release/bin/tblgen)

 

I have checked by libstdc++, with a higher version:

         [wuxi at ppidellsc1420 lib]$ rpm -q libstdc++

libstdc++-4.1.1-52.el5

Well. as libstdc++ is published with gcc. I am wondering which version of
gcc I should use ?

Any suggestion on this problem ? Thanks very much
