3 | The default lib search path order is: | ||
4 | |||
5 | 1) LD_LIBRARY_PATH | ||
6 | 2) RPATH from the binary | ||
7 | 3) ld.so.cache | ||
8 | 4) default search paths embedded in the linker | ||
9 | |||
10 | For nativesdk binaries which are being used alongside binaries on a host system, we | ||
11 | need the search paths to firstly search the shipped nativesdk libs but then also | ||
12 | cover the host system. For example we want the host system's libGL and this may be | ||
13 | in a non-standard location like /usr/lib/mesa. The only place the location is know | ||
14 | about is in the ld.so.cache of the host system. | ||
15 | |||
16 | Since nativesdk has a simple structure and doesn't need to use a cache itself, we | ||
17 | repurpose the cache for use as a last resort in finding host system binaries. This | ||
18 | means we need to switch the order of 3 and 4 above to make this work effectively. | ||
