Bug #16359: Psych cannot build against system libyaml.

• Status: Closed

Just to be sure that we are building Ruby in Fedora against system libyaml library, the first step is to remove bundled libyaml contained in Psych 1. Now the build started to fail:

make[2]: Entering directory '/builddir/build/BUILD/ruby-2.7.0-f9d20a1bf1/ext/psych'
make[2]: *** No rule to make target 'yaml/yaml.h', needed by 'psych.o'.  Stop.
make[2]: Leaving directory '/builddir/build/BUILD/ruby-2.7.0-f9d20a1bf1/ext/psych'
make[1]: *** [exts.mk:255: ext/psych/all] Error 2

I suspect this is due to 2 (I have not tried to revert it yet). I would appreciate if Ruby/Psych is buildable against system libyaml again, as it was always the case.

The attached patch which reverts the Psych part of 1 appears to fix the issue for me.

Revert "Update dependencies"

This reverts commit e1b234148829f65bea9f5ecc7018beb782ea6023.

This allows to build Psych against system libyaml again on Fedora.
