MySQL detects on the build machine where the hostname program is located, and uses this value in a number of configuration files and scripts that are generated and installed in the target: output/target$ grep -r "bin/hostname" * etc/inittab:::sysinit:/bin/hostname -F /etc/hostname usr/share/mysql/mysql.server: pid_file=$datadir/mysqlmanager-`/usr/bin/hostname`.pid usr/share/mysql/mysql.server: server_pid_file=$datadir/`/usr/bin/hostname`.pid usr/bin/mysql_install_db:hostname=`/usr/bin/hostname` usr/bin/mysqld_safe: err_log=$DATADIR/`/usr/bin/hostname`.err usr/bin/mysqld_safe: pid_file="$DATADIR/`/usr/bin/hostname`.pid" However, the hostname on the build machine may not necessarily be at the same location as the hostname program on the target. Buildroot has its hostname program (coming from Busybox) in /bin, but some Linux distributions (such as Fedora) use /usr/bin/hostname, causing the incorrect hostname paths above. This commit fixes that by passing the appropriate autoconf cache variable value.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
