Hello I'm relatively new to gcc development and I'm having trouble with different versions of libstdc++.so being used at runtime. Basically I'm creating an api which is used by a third party application (labview) which uses libstdc++.so.5 my api needs to be compiled with libstdc++.so.6. basically when every I run something like this: std::string b = "bee"; std::string c = "see"; std::string a = b + c; I get runtime crash because as far as I can tell the b+c string is allocated with the 6 allocate symbol and deallocated with the 5 dealloc symbol. This issue is detailed in the following gcc bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21405 The resolution appears to be detailed in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24660 As far as I can tell (PLEASE tell me if I'm mistaken) I need to recompile either my gcc compiler (version 4.1.2) or the stdlibc++.so.6 with the --enable-symvers=gnu-versioned-namespaces flag then recompile my application with the new compiler/ stdc++ library. So my question is how do I do this? Do I need to recompile just my stdc++ library or my entire gcc compiler is this documented some where. -- View this message in context: http://www.nabble.com/Compiling-stdc%2B%2B-with-strong-symbol-versioning-tp23618767p23618767.html Sent from the gcc - Help mailing list archive at Nabble.com.
