Paradoxically, building OpenJDK requires a pre-existing JDK. This pre-existing JDK is called the "boot JDK." The boot JDK for building JDK major version N should be a JDK of major version N-1, so for building JDK11, JDK10 would be needed. This requirement is an issue when building on most distributions, as the host JDK tends to be JDK8. The AdoptOpenJDK project provides binaries that can act as the boot JDK to build the target JDK, which is what this package provides. Currently, only a x86_64 host is supported, for two reasons: 1) A 32bit x86 binary distribution is not available from AdoptOpenJDK 2) We didn't had access to a host machine using an architecture other than x86-64 The provided unpack200 has an invalid RPATH and relies on libzlib. When host-libzlib runs the install step, the following error is generated: *** ERROR: package host-libzlib installs executables without proper RPATH: *** $(HOST_DIR)/bin/unpack200 Because unpack200 is a deprecated tool, removing it after installation is safe and fixes the issue.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
