I am sorry, I have forgot to export LD_LIBRARY_PATH and latest tests shows that the error occurs only under MHD 0.9.50.
Under MHD 0.9.52 (git/master), MHD_get_fdset() returns MHD_NO as expected. I also re-read the "The GNU microhttpd Reference Manual" and its says that for creating an external epoll you have to use MHD_DaemonInfo(daemon, MHD_DAEMON_INFO_EPOLL_FD[_LINUX_ONLY], ...) This information differs from notes for MHD_run() in the microhttpd.h file. There is no any information about epoll at all. I suppose the notes should be expanded further to point a developer to look on MHD_DaemonInfo () if one plans to implement an external epoll poller. Thanks! -- With Best Regards, Vitaliy V. Tokarev
