Hello List,

I tried to compile openjdk (from hg.openjdk.java.net/jdk/jdk) on my linux box (current changeset 8bdf2b5f472d). I succeeded after using --disable-warnings-as-errors with the configure script. The reason is that some files are referencing readdirr and readdir64r despite been deprecated with glibc 2.24 in mid 2016!!! Deprecated functions are not going away necessarily. But since you are treating deprecation warnings as errors by default it might be a good idea to use readdir and readdir64 in favor to the deprecated ones or don't treat deprecation warnings as errors in the first place. It would be nice to have openjdk build on a decent linux system like it is described in doc/build.html. I think the functions have been deprecated because the plain readdir version (without *r) became reentrant, too. But I'm not sure about it. -Jan
