Integrate tests into autotools build system

2016-11-17T10:36:55+00:00

Add automake files for the test binaries. If configured to do so, install the test binaries to libexec/mtd-utils and use autoconf to fix the paths in the test scripts. Signed-off-by: David Oberhollenzer Signed-off-by: Richard Weinberger

don't include system headers in dependency files

2015-08-31T21:42:37+00:00

System library headers are not strictly part of our build. If they are changing beneath our feet, then we probably have bigger problems. Signed-off-by: Brian Norris Suggested-by: Mike Frysinger Acked-by: Mike Frysinger Signed-off-by: Brian Norris

autogenerated dependency files are not being utilized properly

2015-08-28T16:02:41+00:00

TL;DR Acked-by: Mike Frysinger ===== Auto-generated dependency rules are not being written correctly, so changes to dependent files (e.g., headers) do not actually trigger rebuilds. The problem =========== It appears that when a dependency generation flag is passed directly to the preprocessor (with '-Wp,...'), it loses information about the output path. So, it just makes up the output name as $(basename).o, with no path information. This yields .*.c.dep files that look like this: flash_lock.o: flash_lock.c /usr/include/stdc-predef.h flash_unlock.c \ (...) and nanddump.o: nanddump.c /usr/include/stdc-predef.h /usr/include/ctype.h \ (...) include/libmtd.h This is the case for both in-tree *and* out-of-tree builds. Naturally, this is a problem for out-of-tree builds. But it is also a problem for in-tree builds, because we use rules like this for builds: $(BUILDDIR)/%.o: %.c and make doesn't recognize $(BUILDDIR)/%.o as the same as %.o even when $(BUILDDIR) == $(PWD). Example failures ================ ## Rebuilding after touching common header doesn't recompile anything $ make (...) $ touch include/libmtd.h $ make CHK include/version.h ## Same for out-of-tree builds $ BUILDDIR=test make (...) $ touch include/libmtd.h $ BUILDDIR=test make CHK include/version.h I noticed this when seeing that flash_lock would not get rebuilt when modifying flash_unlock.c (where 99% of the source code lies): $ make (...) $ touch flash_unlock.c $ make CHK include/version.h CC flash_unlock.o LD flash_unlock The fix ======= Just pass -MD straight to the compiler, and make sure to specify the output file for the dependency info with -MF.

rewrite build system to avoid recursion

2011-06-27T06:07:07+00:00

The ubi-utils/src/ subdir is tossed as it just complicates things for no real gain. The dictionary.h header is relocated to the ubi-utils/include/ since other headers in there need it. The top level clean is replaced with a `find -delete` on objects, so it might prune more than necessary, but many projects now do this sort of thing and no one complained there. A "mkdep" helper generates the actual rule, and the variables are used with "foreach" to expand these automatically. The tests subdir is updated only to reflect the ubi-utils source move. Otherwise, it is left untouched as making that non-recursive isn't really worth the effort. While we're gutting things, also through in kbuild style output while building to make things more legible.

Fix make install errors

2010-10-27T18:27:31+00:00

This patch heals 'make install' which tried to install the utilities to '/usr/local//usr/sbin'. Reported-by: Charles Manning Signed-off-by: Mike Frysinger Signed-off-by: Artem Bityutskiy

mtd-utils: enable garbage collection of unused function/data sections

2010-10-01T06:29:14+00:00

On my default build, this cumulatively shaves off ~100KiB of unused code and data from the mtd-utils programs. Signed-off-by: Mike Frysinger Signed-off-by: Artem Bityutskiy

mtd-utils: Use $(CURDIR) in place of $(PWD)

2010-09-28T06:47:14+00:00

$(PWD) comes from the shell and may cause unexpected side effects when using "make -C". $(CURDIR) is defined internally by GNU make. Signed-off-by: Kevin Cernekee Signed-off-by: Artem Bityutskiy

mtd-utils: move libmtd source files to lib/ subdirectory

2010-07-13T10:33:20+00:00

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.

build: add option to not force largefile support

2010-02-15T13:41:42+00:00

Not all systems have largefile support (E.G. uClibc depending on config), so unconditionally enforcing largefile breaks the build. Work around it by adding a WITHOUT_LARGEFILE flag, similar to the existing WITHOUT_XATTR. Signed-off-by: Peter Korsgaard Signed-off-by: Artem Bityutskiy
