macos: add configure --with-external-libev #6485

Both of these problems seem to stem from libev using the epoll-shim, when it actually has support for kqueue. At least building flux-core against the brew version of libev appears to get around them. If we do that on macos then we can also revert fd4dd44 I'll retitle this to reflect the need for configure-fu for external libev |

Problem: libev asserts in ev_epoll.c on macos.
Assertion failed: (("libev: I/O watcher with invalid fd found in epoll_ctl", errno != EBADF && errno != ELOOP && errno != EINVAL)), function epoll_modify, file ev_epoll.c, line 134.
The fact that libev is using epoll, which is not native to macos,
indicates that its configure logic is getting confused by the presence
of the epoll-shim (required for the flux_t handle implementation).
Get around this by adding a configure option --with-external-libev so
we can use the homebrew libev, which is properly configured to use kqueue
instead of epoll.
Fixes flux-framework#6485

Problem:
make checkfails on macos in early unit tests.Just the first couple of issues that may indicate actual problems as opposed to non-portable tests:
libflux/test_future.tfails onlibflux/test_reactor.thangs intest_child(). Possibly child watchers don't work, which is rather criticalThe text was updated successfully, but these errors were encountered:
