All,

I am looking for a clear simple explanation on how to use Graphviz as a
static library.

I need scripts etc. in order to create static libraries from the Graphviz
libraries that I can link with macOS and iOS applications in Xcode.
Graphviz can easily be installed using Homebrew on a Mac and does compile.
However, the result are dynamic libraries. In order to deliver through the
Apple App Stores (macOS & iOS) I would like to use static libraries.
Another problem that I try to avoid is the configuration file (=E2=80=9Ccon=
fig6=E2=80=9D)
for graphviz that doesn=E2=80=99t work well with the Sandbox.

All of this was already done once by Glen Low. He gave instructions that
path the way (see first link below). I believe this to be relatively easy
task for somebody that is used to GNU autotools (./configure, make, make
install). Unfortunately, I lack knowledge of GNU Autotools to take it
further.

Solution must have:

   1. Clear repeatable steps to create a static library for Graphviz that
   includes the main plugins (as provided by Glen Low, however some of his
   library settings might be outdated).
   2. Solution must not use the graphviz configuration file config6 at all.
   Instead a static initiation is needed. I assume that such an initiation
   involves to set lt_symlist_t lt_preloaded_symbols[]. See the
   builtins.c file from Glen Low (see below).
   3. Solution must be compilable & executable for macOS Sierra without any
   dynamic graphviz libraries. I need to be able to reproduce the steps. An=
y
   additional comfort is much welcome.
   4. Solution is not allowed to depend on any none-standard dynamic
   libraries. I want it to be able to run on any Mac. And I want to be able=
 to
   distribute through App Store.
   5. A small demo program showing that communication to library works. I
   have a minimal working Swift wrapper below but another wrapper might be
   enough.


Solution should have:

   1. Should work together with
   https://github.com/TheMadOne/GraphvizWrapper/blob/master/GraphvizWrapper=
.swift
   .
   2. Should work together with
   https://github.com/TheMadOne/GraphvizWrapper/blob/master/GraphvizWrapper=
Tests/useGV.swift
   3. Should come with a small sample Xcode project that puts it all
   together.
   4. An iOS version should be covered. I believe that it would only entail
   small changes.


Nice to have:

   1. Selection of included libraries. How can one add one or more
   libraries?
   2. Result checked in as Homebrew formula or as a GitHub open source
   project (e.g. https://github.com/TheMadOne/GraphvizWrapper/, please note
   that that GitHub project is a failed attempt where I tried to package
   dynamic libraries). I think the great Graphviz library should be availab=
le
   for everybody that wants to use the App Store.
   3. Result is configured as a Framework for macOS and iOS. This might
   make it easier.


Relevant links:

   - Overall, but outdated, guidelines from Glen Low:
   http://marc.info/?l=3Dgraphviz-devel&m=3D132335419922240 I believe this =
is
   rather complete. A few comments:
      - The builtins.c file is meant to replace the need for config6 file
      by providing a static initiation of plugins
      - cgraph seems to be standard by now
      - A few other libraries might be outdated. I am mostly interested in
      basic plugins.
      - I am not understanding why he wants directories created and what
      they are used for.
   - http://www.graphviz.org/content/graphviz-iphone - another interesting
   comment from Glen Low.
   - http://www.graphviz.org/pdf/libguide.pdf - Graphviz as a library,
   however this is based on dynamic libraries


I opened a $100 bounty to solve the above. Please have a look:

Thank you for helping me!

One more thing. I know that a Bounty is quite unusual. I have wasted so
much time. For some odd reason I didn't come up with the idea of posting my
question here. Only when I realised that I need more attention to my bounty
I considered this forum. My apologies. I don't want to upset anybody. I
simply have wasted already too much of my hardly available spare time.

Kind regards,
TheMadOne
