This fork does not depend on glib; it uses Mono's clean-room reimplementation under MIT/X11 license.
The most restrictive license down the chain now should be MPL (Cairo), I hope. The companion eglib is here. Add glib-2.0.pc to pkg-config and the rest should work. Put eglib in /root/eglib or modify glib-2.0.pc. Oh, and we have HarfBuzz now (the default renderer in this, do not need Pango anymore unless you need spacing calculations). To compile:
export LIBS=-lharfbuzz -lharfbuzz-icu
This does not respect your font settings; use these instead:
export GDIPLUS_FONT_PATH=
export GDIPLUS_FONT_SIZE=
GDIPLUS_FONT_SIZE scales the font instead by /12.0 (24 scales 2x, etc.).
default for fonts is NotoSans-Regular.ttf, should be present in the working directory. Also: HarfBuzz script can be set at g_hb_script enum (harfbuzz-private.h). The default is set to Tamil. Or you can build it with Pango if you want (LGPL) but might as well use the LGPL'd glib then.

Build status:
This requires the libraries used by the Cairo vector graphics library to build (freetype2, fontconfig, Xft2 and libpng).
On OSX you can use Homebrew to install the dependencies:
brew install glib cairo libexif libjpeg giflib libtiff autoconf libtool automake pango pkg-config
brew link gettext --force
On Debian-based Linux distributions you can use apt-get to install the dependencies:
sudo apt-get install libgif-dev autoconf libtool automake build-essential gettext libglib2.0-dev libcairo2-dev libtiff-dev libexif-dev
On Windows you can use Vcpkg to install the dependencies. Run the following commands from the root of the repository from an admin command prompt:
bootstrap-vcpkg.bat
vcpkg.exe install giflib libjpeg-turbo libpng cairo glib tiff libexif pango --triplet x86-windows
vcpkg.exe install giflib libjpeg-turbo libpng cairo glib tiff libexif pango --triplet x64-windows
vcpkg.exe integrate install
To build on OSX without X11:
./autogen.sh --without-x11 --prefix=YOUR_PREFIX
make
To build on OSX with X11 (e.g. from XQuartz):
PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig ./autogen.sh --prefix=YOUR_PREFIX
make
To build on Linux:
./autogen.sh --prefix=YOUR_PREFIX
make
To build on Windows, open libgdiplus.sln.
Run the following command from the root of the repository:
make check
To run the tests with Clang sanitizers, run the following command from the root of the repository:
./autogen.sh --enable-asan
make check
To run the unit tests with leak sanitizers, run the following command from the root of the repository:
./autogen.sh --enable-asan
export ASAN_OPTIONS=detect_leaks=1:fast_unwind_on_malloc=0
export LSAN_OPTIONS=suppressions=lsansuppressions.txt
make check
Code coverage stats are generated with lcov. You can use Homebrew on OSX to install the dependencies:
brew install lcov
To run the tests with code coverage, run the following commands from the root of the repository:
./autogen.sh --enable-coverage
make check
lcov --capture --directory src --output-file coverage.info
genhtml coverage.info --output-directory coverage
To view the coverage report, navigate to the coverage directory in the root of the repository and open index.html.
Run the following command from the root of the repository:
make install
--with-pango
This builds libgdiplus using Pango to render (measure and draw)
all of it's text. This requires Pango version 1.38 (or later).
