I am following a tutorial that allows me to build the VPX framework for iOS.
When running:
../libvpx/build/make/iosbuild.sh
I keep getting...
output:
make: *** No rule to make target `dist'. Stop.
iosbuild.sh failed because: build exited with error (2)
Does anyone know what this error might mean?
I have tried:
- creating the directory dist .
- supplying an output directory when running the command.
...which has not worked.
Any help would be appreciated.
