Lws now features optional asynchronous, ie, nonblocking recursive DNS resolution done on the event loop, enable `-DLWS_WITH_SYS_ASYNC_DNS=1` at cmake to build it in. The default libc name resolution is via libc `getaddrinfo()`, which is blocking, possibly for quite long periods (seconds). If you are taking care about latency, but want to create outgoing connections, you can't tolerate this exception from the rule that everything in lws is nonblocking. Lws' asynchronous DNS resolver creates a caching name resolver that directly queries the configured nameserver itself over UDP, from the event loop. https://libwebsockets.org/lws-api-doc-main/html/md_READMEs_2README_8async-dns.html Signed-off-by: Bart Van Severen <bart.vanseveren@barco.com> Signed-off-by: Thomas Devoogdt <thomas.devoogdt@barco.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
