GMP does not build if the host gcc is v4.9 due to the following error
gen-sieve.c: In function 'setmask':
gen-sieve.c:99:3: error: 'for' loop initial declarations are only allowed in C99 or C11 mode
for (unsigned i = 0; i < 2 * a * b; ++i)
^
gen-sieve.c:99:3: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 to compile your code
The gen-sieve utility was added in GMP v6.3.0. It is built using
CC_FOR_BUILD (host compiler) during cross compilation as it generates
build files. Autoconf does not have a macro for add -std=c99 to
CC_FOR_BUILD, so it must be set manually. For the target, it is set
correctly thanks to the AC_PROG_CC_C99 macro.

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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
