Dear list,
I'm trying to create an HTTP server for an ARMv7 device.
But MHD_start_daemon returns NULL, and I don't know how to go from there.
The device uses kernel:
# uname -a
Linux buildroot 4.0.0-ADI-1.3.0 #1 PREEMPT Thu Sep 15 16:03:17 UTC 2022 armv7l
GNU/Linux
And libc:
# /lib/libc-2.18.so
GNU C Library (GNU libc) stable release version 2.18, by Roland McGrath et al.

I cross-compiled libmicrohttpd-0.9.75 with --enable-messages, and call
MHD_start_daemon as
following:
daemon = MHD_start_daemon (MHD_USE_INTERNAL_POLLING_THREAD | MHD_USE_ERROR_LOG,
PORT, NULL, NULL, &respond, NULL, MHD_OPTION_END);
Unfortunately, MHD_start_daemon returns NULL. Here's the output snippet of
strace:
write(1, "Starting HTTP server.\n", 22) = 22
brk(NULL) = 0x5a000
brk(0x7b000) = 0x7b000
eventfd2(0, EFD_CLOEXEC|EFD_NONBLOCK) = -1 ENOSYS (Function not implemented)
write(2, "Failed to create inter-thread co"..., 78) = 78
What's going on? And what can I do?
Kind regards,
Roel Janssen
