Fixes: http://autobuild.buildroot.net/results/a7e2631d06634d768faf5c1d02712cc9b38562c6/ Investigation of nios2 config.log shows that this is caused by the "infamous" _gp link issue on codesourcery toolchains: configure:9118: /ssd1/thomas/autobuild/instance-0/output/host/usr/bin/nios2-linux-gnu-gcc -o conftest -O2 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 conftest.c -ldevmapper-event >&5 /ssd1/thomas/autobuild/instance-0/output/host/opt/ext-toolchain/bin/../lib/gcc/nios2-linux-gnu/4.8.3/../../../../nios2-linux-gnu/bin/ld: /ssd1/thomas/autobuild/instance-0/output/host/usr/nios2-buildroot-linux-gnu/sysroot/usr/lib/crt1.o: undefined reference to symbol '_gp' /ssd1/thomas/autobuild/instance-0/output/host/usr/nios2-buildroot-linux-gnu/sysroot/usr/lib/libdevmapper.so.1.02: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status As with other cases, fixed by disabling this package when codesourcery toolchains are in use.

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.
