MySQL+XtraDB: fixing compilation errors

Trying to launch MySQL with the new XtraDB engine. First, I downloaded MySQL sources with patches by Percona and untarred them. They compile without errors and MySQL starts without problems. However, this tarball uses InnoDB, while we wanted to test XtraDB.

Next, I downloaded XtraDB 5.1.42-1.0.6-9 sources from Percona web-site. According to the installation instructions, to use XtraDB, you have to replace the contents of storage/innobase directory with the contents of the XtraDB archive. This time, I received two error messages during the compilation phase, but both of them had already been addressed by the developers and described at Percona's In the first case, the file handler/ contained a minor error at line 801: error: invalid conversion from ‘const char*’ to ‘char*’

To fix this,

if((p = strchr(index->table_name, '/')))

in line 801 in handler/ has to be replaced with:

if((p = strchr((char *) index->table_name, '/')))

Then I got another error message: undefined reference to `active_mi'. To solve this second issue, I had to add disable compilation of MySQL embedded server by adding the following option to the ./configure script: --without-embedded-server.

So, finally, make command succeeded and I tried to install MySQL, but then there was the third error:/bin/sh: @MKDIR_P@: command not found. Fortunately, someone else had seen this message before and the solution is available here. In the file /storage/innobase/ line MKDIR_P = @MKDIR_P@ must be replaced with MKDIR_P = @mkdir_p@.

So, to save your time, do these three modifications before you run ./configure. So, the session transcript would look like this:

$ wget\
$ wget\
$ tar -xjf mysql-5.1.26-percona.tar.bz2
$ tar -xzf percona-xtradb-1.0.6-9.1.tar.gz
$ rm -r mysql-5.1.26-percona/storage/innobase/*
$ mv percona-xtradb-1.0.6-9.1/* mysql-5.1.26-percona/storage/innobase
$ cd mysql-5.1.26-percona/
mysql-5.1.26-percona$ sed -i 's/strchr(index/strchr((char *) index/' storage/innobase/handler/
