The `etc/virtual` file declares the default package to be built for
virtual dependencies declared as "virtual?foo" in $depends.
Before this change, the run-time dependency was added as is to the final
binary package but no pkg providing this virtual pkg was built.
With this file we declare the *default* pkg to be built.
NOTE: "virtual?foo" is only applicable to *run* time dependencies, i.e
only those declared in $depends.
This should result in a considerable performance improvement, because the
expensive configuration phase of all dependencies is skipped.
Hopefully this does not introduce build issues :-)
... otherwise deps specified by the cross-vpkg-dummy pkg aren't
taken into account. Assume that version provided by the vpkg is
good enough for building.
That means that version comparators are not supported anymore in
hostmakedepends and makedepends.
This will ensure that a pkg is always built with the same build dependencies
everywhere, if the srcpkgs tree is uptodate.
The build.sh script is now responsible to handle all the logic to build
a source package and its subpackages, as well as all its required
build dependencies. Thanks to this and subshells, dependencies are now
built into its own child process, creating a process tree that can go
nested as long as your system allows forking and has enough memory :-)
This fixes some issues that have been while building pkgs that have lots
of nested dependencies.
- This should work for almost 90% current packages, as reported by OpenBSD/ports.
- Packages that use install -o <user> -g <group> will get fixed progressively.
- xbps-create(8) by default sets pkg files as 0:0, if any pkg needs special
permissions those can be set via INSTALL scripts (for now).
...otherwise the following would happen:
- foo depends on musl
- musl is provided by cross-vpkg-dummy
- musl is then detected as resolved and it's not built.
The `etc/defaults.virtual` file contains the default replacement
for our use cases; at this moment we only use it to use `eudev`
rather than `systemd` for udev.
If `etc/virtual` exists it overrides the settings of `etc/defaults.virtual`.
The syntax "pkg?vpkg" can be used in hostmakedepends, makedepends and depends;
but the "virtual" keyword can be declared specifically for runtime dependencies
(depends).
Run-time dependencies declared via "${depends}" are now also part of the
build process, but those are not installed to the master directory; rather
those dependencies are only checked if a binary package exists in a
local repository to satisfy the required version.
Thanks to @dominikh for idea and suggestions.
The new xbps-src configuration file is `etc/conf` where you can
add your local overrides from defaults set via `etc/defaults.conf`.
To use this xbps-src, run these steps:
$ make
$ sudo make setup (to make chroot helper setgid)
$ ./xbps-src ...
