Hi Kayvan,
I (and others on the lyx-users list) have had problems installing the lyx-1.2.0 rpms on redhat 6.2 because it is missing the library file: libstdc++-libc6.1-2.so.3. My system has the libstdc++-2.9.0-30 rpm installed (the latest that rpmfind found) which provides libstdc++-libc6.1-1.so.2. Where can I get the new libstdc++ rpm that you used to build with? I also tried building from the .src.rpm, but the compiler crashed with an internal error :-/ (Odd since I've not installed any special version of gcc -- just the one provided by Ximian's Redhat 6.2 channel). Are you using a non-redhat6.2-standard gcc? Hope you can help, Tim (cc-ing to the mailing list) -- // This message is intended for the use of the individual or entity to which it is addressed and may contain information that is privileged and/or confidential.
