Thread-topic: [Maria-discuss] Cross compile issue

Dear Sergei,

A little understand but not totally.
My native compile directory is "/home/johnson/SanSoft/model/Phoenix_130313/Package/mariadb/native" using "make import_executables"
The below is my cross.cmake file content,
  SET(CMAKE_SYSTEM_NAME Linux)
  SET(CMAKE_SYSTEM_PROCESSOR x86_64)
  SET(STACK_DIRECTION 1)
  SET(CMAKE_C_COMPILER   /home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-gcc)
  SET(CMAKE_CXX_COMPILER /home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-g++)
  SET(CMAKE_FIND_ROOT_PATH  /home/johnson/SanSoft/model/Phoenix_130313/build/sysroot)
  SET(IMPORT_EXECUTABLES  /home/johnson/SanSoft/model/Phoenix_130313/Package/mariadb/native)
  SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
  SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
  SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

My configure command is listed as below,
PATH=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/:/bin:/sbin:/usr/bin:/usr/sbin AR=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-ar AS=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-as LD=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-ld NM=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-nm CC=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-gcc GCC=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-gcc CXX=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-g++ RANLIB=/home/johnson/x86_64_TCglibc-2.19-3/usr/bin/x86_64-buildroot-linux-gnu-ranlib \

                -DCMAKE_TOOLCHAIN_FILE=../cross.cmake

I get two errors about IMPORTFILE-NOTFOUND and XtraDB as below,

Yes, that's why I suggested to search the mailing list too. I wasn't sure there's something in the knowledge base :(

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_build_created_during_the_build

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.

Sergei
