description |
This bug hampers my local development / research as I simply cannot successfully build the 'tests' variant locally.
The build failure seems to be:
* libLLVMSupport.a requires -lpthreads -ldl
* something links to that library
* it fails to specify those depencencies
I'm trying to understand the build system enough to know if the linkage dependencies are defined in one place (for each .a) or is this a separate per-executable responsibility.
The actual build can be reproduced by https://github.com/zyga/android-build-scripts
The actual error message is:
(to be updated as current build fails again, make is not stable for some reason) |
