This basically allows configure to complete and set up a configuration suitable for building the BSD port for supported platforms (FreeBSD, OpenBSD and NetBSD.)

The flag _BSDONLY_SOURCE is defined for all the BSD's except for Apple MacOS, while the existing _ALLBSD_SOURCE includes Apple MacOS.

For the BSD's we set the OPENJDK_TARGET_OS_ENV variable to distinct values reflecting the BSD variant being built. This is used to distinguish build flags, library locations and what libraries and modules to include for the various builds.

As an example, FreeBSD includes the ALSA library, and should build the Serviceability Agent, while the other BSD's do not.

A happy FreeBSD user passed by, was delighted to see that this PR didn't break any build on other platforms, that even the tests were passing on those, and decided to give this a try on his system.

So he installed some stuff with pkg install bash autoconf gmake zip alsa-lib cups fontconfig openjdk25

And then ran the following command:

$ bash configure --with-toolchain-type=clang --with-alsa-include=/usr/local/include/alsa --with-cups-include=/usr/local/include --with-fontconfig-include=/usr/local/include

(Noting that configure was not executable)

To get the following output:

FREEBSD:~/bsd-port $ bash configure --with-toolchain-type=clang --with-alsa-include=/usr/local/include/alsa --with-cups-include=/usr/local/include --with-fontconfig-include=/usr/local/includ

A new configuration has been successfully created in

The user didn't dare to try to make the resulting build configuration at that moment, because the dinner was getting cold.

While having dinner he thought that many other more experienced FreeBSD users could be interested in giving this a run in their own systems, or even contribute to this somehow. But then maybe those users didn't know about this effort. After a long working day, the user fell into a deep sleep, dreaming with Java on FreeBSD.

@vieiro Thanks for verifying that the configuration passes :)

And you're right, this is just the first step, so in itself not enough to build for FreeBSD yet. You will find a complete port for the current mainline in the battleblow/jdk repo. By now this passes all tier1 tests on AMD64, and all but one on Aarch64. (Except for a handful more if running on ZFS, as ZFS is not (yet?) able to give the guarantees required by posix_fallocate(3).

We also do have OpenJDK for FreeBSD in the ports tree and in pkg. Up to and including the latest OpenJDK 25.
