Hello All! I have noticed that MySQL does not distribute a static linked binary of MySQL x86_64. I ran into the pthread_rwlock_wrlock hang with nptl bug on an earlier install of Fedora Core 2. The MySQL binary version I am using now is mysql-pro-4.0.26-unknown-linux-gnu-x86_64-glibc23.tar.gz which is dynamically linked, by statically linking the binary on a system with the latest patches apply to NPTL I could just install the binary instead of upgrading to Fedora Core 4. So, my questions are: 1) Is there a reason for not distributing static linked binary for 64bin platforms? 2) I am looking at compiling MySQL myself for an Intel Xeon EM64T box using pgcc, any insight on compiler options to get the best performance? Thank you all for you help! Regards, --Dave David W. Juntgen Medical Informatics Engineering Inc. Phone: 260.459.6270 Fax: 260.459.6271
