2021-02-28mtd-utils: Use AC_SYS_LARGEFILESascha Hauer
Currently mtd-utils on 32bit systems fail on devices >2GiB due to off_t being a signed 32bit type. Add AC_SYS_LARGEFILE to make off_t a 64bit type. Adding AC_SYS_LARGEFILE results in _FILE_OFFSET_BITS being defined to 64 in include/config.h. To let this have an effect we must make sure that include/config.h is included before all other includes which is archieved by adding its inclusion to CPPFLAGS.

2017-06-28Use autoconf header detection correctly for libmissingDavid Oberhollenzer
AC_CHECK_HEADERS already makes sure our config header contains a HAVE_$FOO_H macro if a header was found. There is no need to awkwardly set our own Automake conditionals and check for it all over the place in the Automake files. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2016-11-17Add libmissingDavid Oberhollenzer
This patch adds a libmissing library to mtd-utils, containing implementations of functionality found in glibc but typically missing from embedded C libraries such as uclibc ot musl. For now, the library only contains stub implementations of the backtrace*() family of functions.
