When trying to compile the latest jdk8u on linux I get failures over warnings with the register keywords.
I'm using https://github.com/openjdk/jdk8u-dev.git which seems to be pretty up to date (I'm using master), and last commit is less than two days ago. This is a workaround I had to use: diff --git a/hotspot/make/linux/makefiles/gcc.make b/hotspot/make/linux/makefiles/gcc.make index 7dde7f0963..81f156574a 100644 --- a/hotspot/make/linux/makefiles/gcc.make +++ b/hotspot/make/linux/makefiles/gcc.make @@ -202,7 +202,7 @@ else endif # Compiler warnings are treated as errors -WARNINGS_ARE_ERRORS = -Werror +WARNINGS_ARE_ERRORS = -Werror -Wno-register But I guess the best solution is to remove the register keywords from the codebase. How is adoptium building it? Does it use specific compiler? Is the supported compiler documented anywhere? FTR using temurin-build repository and scripts, fails for other reasons, and fails even with -D/--podman docker containers. This patch builds it with centos stream 9 on amd64. Am I doing something wrong? What's the recommended way of building jdk8? Thanks, Elazar Leibovich
