From cdee2fde6480549195c819c0dd484883cb4b5d95 Mon Sep 17 00:00:00 2001 From: Jan Mulder Date: Sat, 24 Nov 2018 11:53:15 +0100 Subject: Android build: add explanation for huge hack This had to be embedded in the build process (or better, solved for real). Using Cmake, Clang, NDK 18b, Qt 5.12 beta 4, some Subsurface code does not compile. At this point in time, its fully unclear to me why we see the error as it is. Thing fail deep down in Qt and NDK headers on #include . Error like "::signbit is not in the global namespace". The most logic reason is an improper order in which include paths are constructed in the build process. Any attempt to find the real reason failed. Even very similar command lines from a qmake build that succeed fail with a cmake style build. The very very dirty hack is commenting out some lines in NDK 18b: "./android-ndk-r18b/sources/cxx-stl/llvm-libc++/include/cmath Comment lines 313-325, and all build, links and runs with no errors related to this known at this point.
