2016-11-02	Add software packages for oem needs library	tte_zheng_wenlong	1	-0/+43
	These recipes is support software packages for oem needs. The librarys include: boost, fixesproto, imagemagick, iptables, Xorg-macros zlib, eglibc(glibc), libcurl, libgif, libneon, mongoose fuse, protocol buffers, bsdiff, module-init-tools libcroco, libtiff, librsvg, libpcap, libtar You can add these librarys by feature 'agl-oem-extra-libs' source meta-agl/scripts/aglsetup.sh -m porter agl-demo [agl-appfw-smack] [agl-devel] [agl-netboot] agl-oem-extra-libs v2[jsmoeller]: - change to ImageMagick recipe (generalize configure append and add dependency) - readd libtar with tarball taken from debian as original git is n/a v3[tte_zheng_wenlong] - add libtar and libtar-dev in packagegroup-ivi-common-core-os-commonlibs.bbappend - modify README.md to explain build command. v4[tte_zheng_wenlong] - modify mongoose license from GPLv2 to MIT. - delete [] for agl-oem-extra-libs for README.md Change-Id: I1f9d2f1c023f332d528918c3f730ee0360a1f497 Signed-off-by: tte_zheng_wenlong <wenlong_zheng_za@mail.toyota.co.jp> Signed-off-by: Jan-Simon Möller <jsmoeller@linuxfoundation.org>
