I was trying to compile open-vm-toos package (9.0.0-782409) under buildroot env and it fails in one file. Below is log of the error. I narrowed it down on something to do with locale includes. Tried to doff standard locale includes vs those available under buildroot env, and there's no difference. Which include I'm missing (Maybe something to pass explicitly to CFLAGS to configure script of open-vm-tools)?
