Summary0009667: tutorial is outdated
DescriptionThe tutorial at https://www.gnu.org/software/libmicrohttpd/tutorial.html seems to have last been updated in 2016.
Much of the code in it doesn't compile since the HTTP handler function return value was changed from 'int' to 'MHD_Result' since then, leading to errors like this:
 error: invalid conversion from ‘int’ to ‘MHD_Result’ [-fpermissive]

Please update the tutorial so the code compiles. Thank you!
Steps To ReproduceRead the tutorial, try to run the code.
TagsNo tags attached.

Additionally, the example on the homepage doesn't compile either with -fpermissive:

error: invalid conversion from ‘void*’ to ‘const char*’ [-fpermissive]

      | ^~~

error: invalid conversion from ‘int’ to ‘MHD_Result’ [-fpermissive]
