2015-12-01trylink: include LDFLAGS when checking linkageMike Frysinger
The user might be including options in their LDFLAGS (like -fuse-ld=gold) that change the behavior of the linker and thus change the results of the flag tests. Make sure we include the user's LDFLAGS when running these tests so we filter out flags that will fail when used later on.

2014-04-02build system: specify '-nostldlib' when linking to .o filesDrew Moseley
For certain cross build scenarios the LD variable is overridden to use the gcc executive to ensure all the target tuning parameters are used. In these cases, the executive errors out as shown below but since this step is only linking to a .o file the standard libs are not needed. $ make LD=gcc applets/built-in.o LD applets/built-in.o /usr/bin/ld: cannot find -lgcc_s /usr/bin/ld: cannot find -lgcc_s collect2: ld returned 1 exit status make[1]: *** [applets/built-in.o] Error 1 make: *** [applets_dir] Error 2 Signed-off-by: Drew Moseley <drew_moseley@mentor.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2013-09-28trylink: only prefix libs with -lMike Frysinger
If our pkg-config queries pass back a flag like -pthread, the trylink script will expand that to -l-pthread. So change trylink to only add the -l prefix to a value that doesn't have a - prefix already. Reported-by: thaehaid@incognitomail.org Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-07-26buildsys: Add helper to list suid appletsBernhard Reutner-Fischer
Add a helper script that lists all applets that - do or may require SUID provileges (busybox.cfg.suid) - do not require SUID provileges (busybox.cfg.nosuid) Some setups prefer to build two busybox binaries, one that is suid which contains all applets that do or may require suid privileges, and a second one for all the rest (which drops suid). To ease splitting these two binaries, generate a list of CONFIG_ items for the suid binary. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-01-30gen_build_files.sh: exclude hidden directoriesPaulius Zaleckas
I am using quilt to manage patches internally. Quilt creates dir .pc and stores unmodified files there. Since I made change in one of Config.src quilt made a copy in .pc/xxx.patch/xxx/Config.src. When I run make it calls gen_build_files.sh and it generates .pc/xxx.patch/xxx/Config.in. Now when I want to pop patch quilt thinks I have made changes to original xxx/Config.in. IMO the best solution is just to ignore hidden directories in gen_build_files.sh. This also results in shorter build time in case busybox is under git/svn versioning, since it avoids searching many directories for Config.src.

2010-11-16gen_build_files.sh: rewrite with sedMike Frysinger
The shell parsing of files is incredibly slow on many systems. With one report, the process was taking a minute or two which made people thing the build was hung. So rewrite the craziness with sed and proper shell functions. On an idle system, this cut the runtime by half. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
