In rhel5, HandlerSocket fails to compile if the package mysql-devel 5.0 is installed.
In the file ./handlersocket/mysql_incl.hpp, mysql_version.h is included and different headers are included depending on the version (less than 5.0.5 and greater than). This causes a strange error in the build run that can be avoided if the path to mysql_version.h in the Percona Server code being compiled is specified before /usr/include.
The path to this include dir is given to the HandlerSocket build via CXXFLAGS, but its toolchain prepends /usr/include to it (in rhel5). A solution is to use MYSQL_CFLAGS instead of CXXFLAGS when calling the configure script, which is prepended to all flags.
The error is present below. Notice /usr/include/mysql is present before /home/jenkins/workspace/percona-server-5.5-rpms/label_exp/centos5-64/target/BUILD/Percona-Server-5.5.19-rel24.0/release/include which is the actual headers directory.
