So, I've built GCC 4.5.1 on my SLES10 server and proceeded to build my new tool chains. Things seemed to be going OK until one program wouldn't run. It complained about needing libstdc++.so with GLIBCXX_3.4.9 or some other version. I searched the libraries in my new tool chain and a number of them refer to specific GLIBCXX versions that are all newer than the one that my system libstdc++.so provides. The only way I can get these programs and libraries to work is to modify my LD_LIBRARY_PATH to point to the GCC 4.5.1 directory that contains the newer libstc++.so. I have 2 questions. First of all, why is it that only some libraries have this requirement. Secondly, what is the correct way of handling this ? I'm assuming that we don't want to mix different versions of this library. I'm guessing that I should do 1 of the following: 1) Install the newer libstdc++.so in the system directory and have all packages use this version 2) Globally set the LD_LIBRARY_PATH for this entire tool chain so that they all pick up the library from the GCC 4.5.1 directory. Thanks in advance. Kris
