Undefined symbols for architecture x86_64 on jsonnet submission

[Steven Smith]

This is a 100% MacPorts default flags or env issue, and nothing to do with Google’s upstream repo or code.

First, the repo’s make command works on macOS <https://github.com/google/jsonnet <https://github.com/google/jsonnet>>:

> make CC=clang CXX=clang++

Second, Homebrew uses this formula for their own macOS distribution. See <https://github.com/Homebrew/homebrew-core/blob/master/Formula/jsonnet.rb <https://github.com/Homebrew/homebrew-core/blob/master/Formula/jsonnet.rb>>, which btw is Google’s recommended install approach.

Third, I’ve tried using this Portfile configuration (without the cmake portgroup), but run into the same issue:

> compiler.cxx_standard 2011
> use_configure       no
> build.target

The only thing left is the environment and flags that MacPorts sets during the call to make.

This tells me it will be possible to turns off all MacPorts build flags so that the Portfile essentially just runs “make CC=clang CXX=clang++” and get a successful build and install.

Is turning off all MacPorts build flags the recommended approach here?

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 ?=
