make: *** [php71-install] Error 1

The part of ~/unit/build/Makefile:983:

php71-install: php71
        install -d $(DESTDIR)build
        install -p build/php71.unit.so \
                $(DESTDIR)build/

I've not found where DESTDIR is defined.

DESTDIR can be defined during installation procedure
DESTDIR=/path/to/install make install

Otherwise you should specify absolute path for all configure parameters or add --prefix parameter. Using relative paths is useful for developing purposes when you run unitd in the same place where you have built it.

Closed issue due to clean ups.
