strerror_r on musl always returns an int since its addition back in 2011 with https://git.musl-libc.org/cgit/musl/commit/src/string/strerror_r.c?id=0b44a0315b47dd8eced9f3b7f31580cf14bbfc01 As a result, setting ac_cv_strerror_r_rc_int to no results in the following build failure since bump to version 1.7.2 in commit783cd8d90d: misc/unix/errorcodes.c: In function 'native_strerror': misc/unix/errorcodes.c:385:9: error: assignment to 'const char *' from 'int' makes pointer from integer without a cast [-Wint-conversion] 385 | msg = strerror_r(statcode, buf, bufsize); | ^ Fixes:783cd8d90d- http://autobuild.buildroot.org/results/9a42a4427ff64d47da61c731abb99d7585781cdd Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> (cherry picked from commit6f34e68217) 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.
