From: Bruce Richardson Date: Fri, 3 Nov 2017 14:47:43 +0000 (+0000) Subject: build: remove library special cases X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=610beca42ea4;p=dpdk.git build: remove library special cases The EAL and compat libraries were special-cases in the library build process, the former because of it's complexity, and the latter because it only consists of a single header file. By reworking the EAL meson.build files, we can eliminate the need for it to be a special case, by having it build up and return the list of sources, headers, and objects and return those to the higher level build file. This should also simplify the building of EAL, as we can eliminate a number of meson.build files that would no longer be needed, and have fewer, but larger meson.build files (9 now vs 14 previous) - thereby making the logic easier to follow and items easier to find. Once done, we can pull eal into the main library loop, with some modifications to support it. Compat can also be pulled it once we add in a check to handle the case of an empty sources list.
