This change adds another fix to the yajl build-system code. This patch checks for isnan function in libc, and if not, it makes sure libm is passed to the linker flags. This change fixes build failure looking like: make[3]: Entering directory `/home/peko/autobuild/instance-2/output/build/yajl-2.1.0' [ 81%] Building C object example/CMakeFiles/parse_config.dir/parse_config.c.o ../yajl-2.1.0/lib/libyajl.so.2.1.0: undefined reference to `__isnan' ../yajl-2.1.0/lib/libyajl.so.2.1.0: undefined reference to `__isinf' collect2: error: ld returned 1 exit status make[3]: *** [verify/json_verify] Error 1 Fixes: http://autobuild.buildroot.org/results/312/31268e4d20aa34bb90c09aa771b1923f979578ab/ and many others Cc: Benoît Mauduit <bmauduit@beneth.fr> Cc: Bernd Kuhls <bernd.kuhls@t-online.de> Cc: Jörg Krause <joerg.krause@embedded.rocks> Cc: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Signed-off-by: Samuel Martin <s.martin49@gmail.com> Tested-by: Bernd Kuhls <bernd.kuhls@t-online.de> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
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.
