Hi, the problem was that gcc and clang are by default extremely strict with regards to conforming to C++, and the -pedantic flag simply made them so strict that it was impossible to compile the JDK with them. In an ideal world we'd be able to compile with -pedantic enabled, but that seems to be a lot of work required before that can be achieved, so it was reverted. In contrast, Visual C compiler is much too lax with what it allows you to get away with by default, so the permissive- flag is needed to make it match clang and gcc's default strictness. Additionally, permissive- is going to become the default on Visual C in the future, so we should add this as a flag to allow the JDK to be prepared when that time arrives ------------- PR Comment: https://git.openjdk.org/jdk/pull/15096#issuecomment-1681596804
