GCC and Clang are able to check the format arguments given to a function and warn the user if there is a error in the format arguments or if there is a potential uncontrolled format string security problem in the code. GCC does this automatically for some functions like printf(), but it is also possible to annotate other functions in a way that it will check them too. This feature is used by glibc for many functions. This patch adds the attribute to the some functions of musl expect for these functions where gcc automatically adds it. GCC automatically adds checks for these functions: printf, fprintf, sprintf, scanf, fscanf, sscanf, strftime, vprintf, vfprintf and vsprintf. The documentation from gcc is here: https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html The documentation from Clang is here: http://clang.llvm.org/docs/AttributeReference.html#format-gnu-format Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 48467
This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to configure your appreciated configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. You can use "scripts/flashing/flash.sh" for remotely updating your embedded system via tftp. The OpenWrt system is documented in docs/. You will need a LaTeX distribution and the tex4ht package to build the documentation. Type "make -C docs/" to build it. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Project http://openwrt.org
