To get WebAssembly templates to actually work, we need to use
Mono 6.6 (currently in preview), which doesn't have tags yet
but is in the `2019-08` branch. So I dehardcoded the `mono-`
prefix for the git tree-ish to allow using `./build.sh 2019-08`.
6.6 doesn't build with msbuild 16.0, so I'm upgrading to its
matching version 16.3. There are no DEB files for 16.3 on the
EOL'ed Ubuntu 14.04, but it seems that the 16.04 packages install
cleanly.
We also backport a patch from mono's master branch to fix wasm
support further, and enable parallel build jobs for make.
The osxcross installation process has been improved and now supports
more recent versions of Xcode than 7, so most of our custom code is
no longer needed.
The xcode packer could also be reworked to use osxcross' SDK packing
script.
Fixes#15.
The previous `['/bin/bash']` was not working, running the image
with `podman run -it <name>` would evaluate to:
```
> sh -c ['/bin/bash']
sh: [/bin/bash]: No such file or directory
```
We force using Emscripten 1.38.47 as there is a regression in 1.38.48
and 1.39.x which makes the generation of our .wasm file fail.
Up until now we used the desktop BCL (compiled with desktop Mono)
for both desktop and Android, but that does not work for WebAssembly
(and we suspect Android issues related to it).
So we now build the Android and WebAssembly BCLs in the relevant
containers, which are later copied in the templates directory to
include on export. We already have the desktop BCL from the regular
build.
The main reason is that upstream Mono tends to miss some
important files in its tarballs, so Git tags appears to be
a more reliable medium.
Also group RUN commands to reduce the number of intermediate
dependencies.
This saves us from pulling gtk2 and gtk3 as weak deps of
perl and git or whatnot... And we don't need to pull in all
the documentation on Ubuntu.
Also ensures that we properly run `dnf clean all` after each
installation.
Adds support for building Mono templates for Android in 3.2/master.
We use the script from https://github.com/godotengine/godot-mono-builds
to build Mono for all arches with the right options, and a patch included
from https://github.com/godotengine/godot/blob/master/modules/mono/build_scripts/patches/fix-mono-android-tkill.diff
which is also necessary.
I also moved the SDK to a `sdk` folder to make the `$HOME` more tidy,
especially since the Mono build scripts install the mono toolchains in
`$HOME` too by default.
Using a git clone for specific mono version tag, as the upstream tarballs
are iffy (the 5.18.1.3 tarball lacks files needed to build on Android).
Install xz/xz-utils and conditionally handle tar.xz tarballs from 6.0+.
On Windows, I ran into a build issue due to `make distclean` being
bogus in 6.0.0.319 (mono/mono#16605), so I worked it around by starting
from a clean folder for each build.
The hotfixed mingw-binutils packages should likely be rebuilt against
Fedora 30's mingw-binutils, but I didn't find the src.rpm in the repo
to do it. There were no functional changes between F29 and F30's
mingw-binutils though, so we should be fine as is:
https://src.fedoraproject.org/rpms/mingw-binutils/commits/f30
The `MONO32_PREFIX` and `MONO64_PREFIX` are no longer used by the
buildsystem (replaced by a `mono_prefix` build option), but I kept them
where relevant to point to non-standard install locations.
* Mono config on MacOSX is not portable from the Linux and Windows
version.
* Rename the compilers so that 'gcc' and 'g++' are the new version by
default.
* Add default environment variables to containers.
