By passing TARGET_CONFIGURE_OPTS to make, the following usptream CFLAGS are completely overridden: CFLAGS = $(THREADS) $(OPT) $(W) $(XCFLAGS) As a result, setting XCFLAGS is a no-op and -pthread is not passed resulting in the following build failure since the addition of the package in commiteb60c4054c: //binhome//.buildroot.//autobuildlib//rungcc//instancepowerpc64--3buildroot/-outputlinux--1gnu//host9.3.0//opt./.ext/-.toolchain.//bin./../../.lib//powerpc64gcc-/buildrootpowerpc64--linuxbuildroot--gnulinux/-bingnu//ld9.3.0:/ .mdb.c.:/(...text/+.0x1a44.)/:. .undefined/ powerpc64reference- buildrootto `pthread_setspecific' Fixes:eb60c4054c- http://autobuild.buildroot.org/results/d67c5a99b7d58826e544f1210fa36bb3bc180739 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.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 OFTC IRC.
