Subject: [PATCH 1003/1013] hotspot: don't rely on old SysV SIGCLD
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
SIGCLD is the old System V name for SIGCHLD, and not
all c libraries implement it, e.g. musl-libc, which
leads to the following compilation error:
| hotspot/src/os/linux/vm/jvm_linux.cpp:157:17: error: 'SIGCLD' was not declared in this scope
| "CLD", SIGCLD, /* Same as SIGCHLD (System V). */
| ^~~~~~
Just make it conditional, so the code compiles everywhere.
