From: Rosen Penev Date: Sun, 7 Apr 2019 06:37:56 +0000 (-0700) Subject: uClibc++: Update to 0.2.5 X-Git-Tag: v19.07.0-rc1~673 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0b2638253321db90e9844f04cd7299c1a2e1633a;p=openwrt%2Fopenwrt.git uClibc++: Update to 0.2.5 Switched to xz archives for smaller size. Removed upstreamed patches. Reorganized Makefile a little bit for clarity. Build/Prepare is not useful anymore. Upstream converted the file to LF. Refreshed config. Removed -ansi option from the original CFLAGS as this was causing long long support to be missing. Removed fPIC. We have the macro $(FPIC) already used. No point in setting fpic and fPIC together. Removed pedantic -Wlong-long warnings as they are not useful. Removed -std=gnu++98. Not only is it unnecessary (it compiles against all standards), it actually results in a size increase. 75843 vs. 75222 (gcc in OpenWrt defaults to g++14). Added --gc-sections to linker flags to reduce size: 72653 vs 75222. Removed warn linker options. They have been upstreamed. Tested on Archer C7v2 and GnuBee PC1.
