From: Thomas Monjalon Date: Tue, 1 Dec 2015 14:04:01 +0000 (+0100) Subject: mk: introduce new install syntax X-Git-Tag: spdx-start~7897 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fae202e2e21cb50cd4df4b1f5688eb5bfeb4a771;p=dpdk.git mk: introduce new install syntax The old install command was: make install T=x86_64-native-linuxapp-gcc DESTDIR=install It still works and can be replaced by these more standard commands: make config T=x86_64-native-linuxapp-gcc 0=x86_64-native-linuxapp-gcc make O=x86_64-native-linuxapp-gcc make install O=x86_64-native-linuxapp-gcc prefix= DESTDIR=install It means the "make install" do not perform any compilation anymore when T is not used. It is done only in pre_install to keep compatibility with the old syntax based on T= option. The default prefix /usr/local is empty in the T= case which is used only for a local install.
