It turns out that uClibc only enables the long double math functions for some architectures (god know why, so what if long double is the same as double, these functions should still be defined). Since python-numpy links with those functions, the module will fail to load on ARM, MIPS and SH. However, python-numpy actually checks for each function if it is really available. Only, it overrides that check for ldexpl and frexpl when long double is the same as double (i.e. in exactly the case the uClibc doesn't have these functions). So add another exception for this.

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.
