I'm cross-compiling ecasound, which goes well up to the point that all binaries get compiled, but fails during (at the end of?) the installation phase.
The thing is, I don't see any error message or anything, so I'm left guessing here:
ecasound: installs files in /home/buildroot/buildroot-2018.02-rc2/output/target//home/buildroot/buildroot-2018.02-rc2/output
make[1]: *** [/home/buildroot/buildroot-2018.02-rc2/output/build/ecasound-2.9.1/.stamp_target_installed] Error 1
make: *** [_all] Error 2
