Hi, Sergei. I'd like to share my recently obtained knowledge :) 1. Mac OS X and sockets. As you know there on Labrador machine that mysql-test-run.pl failed if not run with --tmpdir=/tmp. The problem apparently is that the /Users directory has the access restrictions that /tmp doesn't. I still don't know what exactly was that, but it helps if we revoke all the ACLs with 'chmod -R -N /Users/mariadb'. 2. The 10.0 fails building on my machine, with linking errors in the extra/yassl/, about missing 'operator new[]' and similar. I fixed it locally with that patch: === modified file 'extra/yassl/CMakeLists.txt' --- extra/yassl/CMakeLists.txt 2014-02-26 14:28:07 +0000 +++ extra/yassl/CMakeLists.txt 2014-03-25 07:45:46 +0000 @@ -33,9 +33,10 @@ SET(YASSL_SOURCES src/buffer.cpp src/ce ADD_CONVENIENCE_LIBRARY(yassl ${YASSL_SOURCES}) RESTRICT_SYMBOL_EXPORTS(yassl) +TARGET_LINK_LIBRARIES(stdc++) + INSTALL_DEBUG_SYMBOLS(yassl) Best regards.
