+
+I am building a cryptographically counter-signed IOU application with
+linux phones (GTK4, phosh) as the primary targets.
+
+It will maintain bi-lateral mutual channels of credit and collateral.
+Each change is linked as a chain, and documentation for each change in
+embedded as email-link MIME structures
+
+Dependencies
+
+Below are the library versions of the archlinux component packages I am
+using for dependencies and tooling while working on my own system.
+
+ package version
+ ----------------- ---------
+ gcc 13.2.1
+ graphicsmagick 1.3.42
+ gst-plugins-bad 1.24.0
+ gstreamer 1.24.0
+ gtk4 4.12.5
+ libb64 1.2.1
+ libgcrypt 1.10.3
+ qrencode 4.1.1
+ libxdg-basedir 1.2.3
+ lmdb 0.9.32
+ openldap 2.6.7
+ rustup 1.26.0
+ zbar 0.23.90
+ zlib 1.3.1
+
+The gst-plugins-bad provides libgstzbar.so, used as part of QR scanning.
+
+Other sources
+
+The code expects objects from these source trees to be available
+somehow:

+
+Building
+
+There is no magic pathfinder implemented currently. Thus, you must
+configure the environment for building and linking the external sources
+yourself.
+
+Here is what I use in my local setup.
+
+libcmime
+
+I can't seem to set the cmake build prefix so that the libcmime.pc file
+is generated correctly. Unfortunately, pkg-config is thus off the table.
+
+ git clone -b 0.2.2 https://github.com/spmfilter/libcmime.git
+ https://github.com/spmfilter/libcmime.git
+ mkdir -p libcmime/build
+ cd libcmime/build
+ cmake ..
+ make install DESTDIR=.
+
+Your include path, relative to the repository root directory, will be
+<repo_root>/build/usr/include/lib64 and your ld path will be
+build/usr/include/lib64.
+
+libgstgtk4 (gst-plugin-rs)
+
+The gtk4 part of the code uses the gtk4paintablesink gstreamer plugin
+(for QR scanning). It is part of the gst-plugins-rs source above, built
+as the libgstgtk4.so shared library file.
+
+The specific package to build is gst-plugin-gtk4, which builds the
+plugin at version 0.9.13.
+
+I was able to build with toolchain 1.75-x86_64-unknown-linux-gnu.
+
+ rustup default 1.75.0
+ cargo install cargo-c
+ git clone -b gstreamer-1.22.10 https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
+ cd gst-plugins-rs
+ cargo cbuild -p gst-plugin-gtk4
+
+Environment
