package/openjdk: new package
OpenJDK is a free and open-source implementation of the Java Platform.
This package provides the option to build a client or a server JVM
interpreter.
The default option is the server option, as that is what the majority
of users use. This JVM interpreter loads more slowly, putting more
effort into JIT compilations to yield higher performance.
Unlike most autotools packages, OpenJDK is exceptionally different and
has many quirks, some of which are below:
- X11, alsa, and cups are required to build Java, even if it's a headless build.
See
http://hg.openjdk.java.net/jdk10/jdk10/raw-file/tip/common/doc/building.html#external-library-requirements
for more information.
- host-zip is needed for the zip executable.
- There is no autogen.sh file, instead, a user must call "./configure
autogen."
- OpenJDK ignores some variables unless passed via the environment.
These variables are: PATH, LD, CC, CXX, and CPP.
- OpenJDK defaults ld to the ld binary but passes -Xlinker and -z as
arguments during the linking process, which causes linking failures.
To fix this issue, ld is set to gcc.
- Make -jn is unsupported. Instead, one must use the "--with-jobs="
configure option, and use $(MAKE1).

- drop explanations about CC, LD, CXX, etc. be set to their "actual
binaries" instead of ccache: TARGET_CC/TARGET_LD/TARGET_CXX point
to the compiler wrapper, so the usage of ccache is hidden
- make sure at least one of the variants is enabled in Config.in
- drop the submenu for variant selection
- use system zlib instead of the bundled one. This works fine when
BUILD_SYSROOT_CFLAGS and BUILD_SYSROOT_LDFLAGS are passed
- fix minor nits in the Config.in comments]

of users use. This JVM interpreter loads more slowly, putting more
effort into JIT compilations to yield higher performance.
Unlike most autotools packages, OpenJDK is exceptionally different and
has many quirks, some of which are below:
- X11, alsa, and cups are required to build Java, even if it's a headless build.
See
http://hg.openjdk.java.net/jdk10/jdk10/raw-file/tip/common/doc/building.html#external-library-requirements
for more information.
- host-zip is needed for the zip executable.
- There is no autogen.sh file, instead, a user must call "./configure
autogen."
- OpenJDK ignores some variables unless passed via the environment.
These variables are: PATH, LD, CC, CXX, and CPP.
- OpenJDK defaults ld to the ld binary but passes -Xlinker and -z as
arguments during the linking process, which causes linking failures.
To fix this issue, ld is set to gcc.
- Make -jn is unsupported. Instead, one must use the "--with-jobs="
configure option, and use $(MAKE1).

[Thomas:
- drop explanations about CC, LD, CXX, etc. be set to their "actual
binaries" instead of ccache: TARGET_CC/TARGET_LD/TARGET_CXX point
to the compiler wrapper, so the usage of ccache is hidden
- make sure at least one of the variants is enabled in Config.in
- drop the submenu for variant selection
- use system zlib instead of the bundled one. This works fine when
BUILD_SYSROOT_CFLAGS and BUILD_SYSROOT_LDFLAGS are passed
- fix minor nits in the Config.in comments]
