On uClibc, finite, isinf and isnan are not directly implemented as functions. Instead math.h #define's these to __finite, __isinf and __isnan, which are real functions. This confuses the Ruby configure script which use AC_REPLACE_FUNCS to detect these, as it really checks for a function without including math.h. Because of the naming difference the checks fail, therefore the symbols HAVE_FINITE, HAVE_ISINF and HAVE_ISNAN are not defined. Ruby code relies on those symbols in order to define its own version of the finite, isinf and isnan functions. Since the symbols haven't been defined, those definitions cause conflicts with the already-existing functions.

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