Dear Sergei,
Thanks for your reply. I am sorry that I can NOT find any document about cross compile from knowledge base. https://mariadb.com/kb/en/mariadb/getting-installing-and-upgrading-mar iadb/
Yes, that's why I suggested to search the mailing list too. I wasn't sure there's something in the knowledge base :(

It tries to use my cross compiled extra/comp_err utility to do something at my host machine.
Right... During the build few helper tools are compiled and used in the build. See http://www.cmake.org/Wiki/CMake_Cross_Compiling In particular, we implement the solution from http://www.cmake.org/Wiki/CMake_Cross_Compiling#Using_executables_in_the_bui... So, you need to build for the native platform first. Not everything, just "import_executables" target: make import_executables This will create import_executables.cmake file. When you cross-compile you'll need to set IMPORT_EXECUTABLES to the path to that file. Regards, Sergei
