I was wondering if anyone had success in porting the Linux versions of the Mongoose web server or the Civetweb web server to FreeBSD. I've tried to do a Make, but there is a compatibility issue between Linux and BSD, in that it cannot find -ldl. I've seen reference to this in a google search, and the recommended solution is probably beyond my skill level.
Linux uses GNU make by default. Its makefiles tend to be incompatible with FreeBSD's make. So you need to install GNU make using the /usr/ports/devel/gmake port. The program is called gmake on FreeBSD.
So for mongoose, download the latest mongoose source from github.
Then install GNU make using the /usr/ports/devel/gmake port. Unpack mongoose;
> tar xf mongoose-5.3.tar.gz
> cd mongoose-5.3/examples
Then compile it;
> gmake
cc hello.c ../mongoose.c -o hello -W -Wall -I.. -pthread -g -pipe
perl mkdata.pl websocket.html > websocket_html.c
cc websocket.c websocket_html.c ../mongoose.c -o websocket -W -Wall -I.. -pthread -g -pipe
cc server.c ../mongoose.c -o server -W -Wall -I.. -pthread -g -pipe
cc post.c ../mongoose.c -o post -W -Wall -I.. -pthread -g -pipe
cc multi_threaded.c ../mongoose.c -o multi_threaded -W -Wall -I.. -pthread -g -pipe
cc upload.c ../mongoose.c -o upload -W -Wall -I.. -pthread -g -pipe
cc auth.c ../mongoose.c -o auth -W -Wall -I.. -pthread -g -pipe
Civetweb also compiles without errors using gmake.
