looks different form the ones of Postgres 10
Looking at your Makefile, it seems to be expecting that CXXFLAGS will
be honored in the build, and it isn't being.
As far as I can see from pgxs.mk, you're supposed to spell that
PG_CXXFLAGS. Probably, it accidentally worked to do it the other
way in v10, but no longer does, likely as a result of the fact that
there's now some minimal amount of C++ code in core PG.
I was looking at that and was trying to figure out this from pgxs.mk:
# PG_CXXFLAGS -- will be appended to CXXFLAGS
...
ifdef PG_CXXFLAGS
override CXXFLAGS := $(CXXFLAGS) $(PG_CXXFLAGS)
Was wondering if this might be culprit(from example in pgxs.mk):
# include $(PGXS)
The OP does not have that in their make file.
I'm a little dubious about whether overriding CXX is a good idea now, too.
(Likely the core setting is the same, but if it were pointing at a
different compiler that could cause trouble.)
