Per https://guide.macports.org/#reference.phases.installation.list-modifiers <https://guide.macports.org/#reference.phases.installation.list-modifiers>, I’ll try starting with a blanket -delete of everything, try to get to the basic working make, and divide-and-conquer to isolate the issue. Maybe this?

Are these MacPorts configure flags used in the build stage? Here’s the current not-working Portfile: https://github.com/macports/macports-ports/blob/4a9cd2d6b34e6d48e22bfb608529e900f49f8dcb/devel/jsonnet/Portfile <https://github.com/macports/macports-ports/blob/4a9cd2d6b34e6d48e22bfb608529e900f49f8dcb/devel/jsonnet/Portfile> > On Nov 23, 2019, at 8:25 AM, Chris Jones <jon...@hep.phy.cam.ac.uk> wrote: > > > >> On 23 Nov 2019, at 12:57 pm, Steven Smith <steve.t.sm...@gmail.com> wrote: >> >> >>> >>> You need to try and isolate the one causing the issue, if you believe it is >>> something MacPorts is appending to the env, and then address that >>> specifically. >> >> That’s what I’m asking for help to do. >> >> How are these flags and environment variables set within a Portfile? >> >> I don’t know enough about the MacPorts build design or clang options enough >> to go through all the combinatoric flag settings, or to divide-and-conquer >> the problem. >> >> Here are the flags set by Google’s upstream repo, >> <https://github.com/google/jsonnet/blob/master/Makefile >> <https://github.com/google/jsonnet/blob/master/Makefile>>: >>> CXXFLAGS ?= -g $(OPT) -Wall -Wextra -Woverloaded-virtual -pedantic >>> -std=c++0x -fPIC >>> CXXFLAGS += -Iinclude -Ithird_party/md5 -Ithird_party/json >>> CFLAGS ?= -g $(OPT) -Wall -Wextra -pedantic -std=c99 -fPIC >>> CFLAGS += -Iinclude >>> MAKEDEPENDFLAGS += -Iinclude -Ithird_party/md5 -Ithird_party/json >>> EMCXXFLAGS = $(CXXFLAGS) -g0 -Os --memory-init-file 0 -s >>> DISABLE_EXCEPTION_CATCHING=0 -s OUTLINING_LIMIT=10000 -s >>> RESERVED_FUNCTION_POINTERS=20 -s ASSERTIONS=1 -s ALLOW_MEMORY_GROWTH=1 >>> EMCFLAGS = $(CFLAGS) --memory-init-file 0 -s DISABLE_EXCEPTION_CATCHING=0 >>> -s ASSERTIONS=1 -s ALLOW_MEMORY_GROWTH=1 >>> LDFLAGS ?= >> >> >> How are these variables and flags unset/reset within a Portfile? > > See > > https://guide.macports.org/ <https://guide.macports.org/> > > There is a section in there explaining how CFLAGS etc. are set. >>
