2016-12-06common: Fix 'unchecked return code' warningsBoris Brezillon
Several tools are simply not checking return code of functions marked with 'warn_unused_result'. Provide wrappers for the read/write functions to avoid patching old code and providing proper error handling. Fix the remaining ones (calls to fgets() and system()).

2016-12-06common: Fix PRI{x,d}off definitions for x86_64 platformBoris Brezillon
Compiling for x86_64 generates a lot of warning because the PRIxoff_t and PRIdoff_t are not properly defined, which comes from the missing SIZEOF_LONG definition. Use the autotools to generate a config.h header, include this header from common.h and ask autoheader to generate the SIZEOF_LONG and SIZEOF_LOFF_T definitions. Use these new definitions to assign the proper descriptors to PRIxoff_t and PRIdoff_t. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
2016-11-17Merge rest of ubiutils-common into libmtd commonDavid Oberhollenzer
This patch moves the remaining 3 functions from ubiutils-common.{c,h} into libmtd common.{c,h}. The functions are only generic utility functions that other mtd-utils programs may also find usefull and every program that uses libubi links against libmtd anyway so there is no real reason for keeping around a seperate ubiutils-common with only generic helper functions.

2016-11-17Unify version string printingDavid Oberhollenzer
When a program does sophisticated enough command line processing (i.e. getopt), make sure it responds to -V and --version. When a program prints a version string, make sure it uses the common_print_version macro to print out its name, that it is part of mtd-utils and the mtd-utils version from the build system in a fashion similar to common program packages like the GNU coreutils. When a program responds to -V/--version or -h/--help, make sure it reports success exit status.

2016-11-17Change build system to autotoolsRichard Weinberger
This patch is largely based on Richards original RFC. The major differences to the RFC patch are: - Add missing sumtools & mtdpart targets - Fix name of mkfs.jffs2 target - Add missing subdir-objects option for non-recursive make - Move all automake options to configure.ac - Add manpages to install target - Make XATTR & LZO support configurable - Install binaries to sbin directory like in the old build system - Install flash_erase wrapper script - Add files missing from distribution target Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at> Signed-off-by: Richard Weinberger <richard@nod.at>

2016-04-18include sys/sysmacros.h for major/minor/makedevMike Frysinger
These functions have always been defined in sys/sysmacros.h under Linux C libraries. For some, including sys/types.h implicitly includes that as well, but glibc wants to deprecate that, and some others already have. Include the header explicitly for the funcs.

2015-05-28include/common.h: fix build against muslJörg Krause
Like uClibc version older than (not yet released) 0.9.34 musl does not have a rpmatch() implementation. uClibc defines both __UCLIBC__ and __GLIBC__. So first check for uCibc and its version and then for a non glibc implementation (like musl). Note, musl does not define __MUSL__.

2014-04-21include/common.h: fix build against recent 0.9.33 uClibcBaruch Siach
An implementation of rpmatch() was backported to the 0.9.33 branch of uClibc. So the uClibc version check introduced in commit 50c9e11f7e (include/common.h: fix build against current uClibc) is not enough. Rename the local rpmatch() implementation to avoid collision.

Commit dbe0fd17f2 (mtd-utils: new prompt() helper for talking to the user) introduced a rpmatch() call.

2011-02-25mtd-utils: common.h: simple_strtoll type usageBrian Norris
We must use "long long" and "unsigned long long" types when implementing the functions "simple_strtoll()" and "simple_strtoull()", respectively. This prevents casting/truncation errors on systems where "long" is not the same size as "long long" (that is, on most systems).

2010-07-13mtd-utils: move libmtd source files to lib/ subdirectoryKevin Cernekee
Source files for libmtd, crc32, and fec are scattered throughout the tree. Move them to a central location so they can be built into a common "libmtd.a" library used by all mtd-utils programs. This patch only renames/deletes files and does not change the content. Also modify the build system and source code so that libmtd.a can be built from a "common" location (lib/). Statically link all utilities at the top level with libmtd.a . Minor changes to mkfs.ubifs to allow using the common crc32 implementation.
