So you suggested basically 3 solutions: > 1. Build on the oldest release of glibc you plan to support (we > build on ancient RedHat 6.2 with glibc-2.1, and it runs *everywhere*). > 2.

I am running a linux debian stable, let say I install g++3.4, if I build an executable using this particular I should be garantee that the binary use a quite old GLIBC API, right ? Since this is not listed in your solution, I am guessing there is a good reason, but I do not see what's wrong here... You seems to have a quite elaborate solution since you can run 'everywhere' in my case, since my project is written in C++, I will only be able to support system that understand ABI version=2 of g++. So I thought using the earliest possible implementation of ABI version=2 in g++ 3.4 should solve my issue. As a side note, since solution #1 seems to be used internally in solution #2 (apgc is shipped with some kind of old glibc), do you have any further documentation on how to do that. apgcc is not part of debian... I might eventually try solution #3 as support for cross compilation seems to be a lot easier when using cmake (http://cmake.org), I'll try to reproduce what was done there. Thanks again for your help -Mathieu _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
