Build failure: no matching function for call to ‘Groupsock::Groupsock(UsageEnvironment&, in_addr&, Port&, int&) #220

Looks like a function signature changed in the latest live555 version? Here's the full build output:

Groupsock build error.txt

nettings commented 3 years ago

Had a hard time figuring out which version of live555 was used for this build. Checking on their website, I find the following files and timestamps:

  | live.2020.12.11.tar.gz | 2020-12-10 16:44 | 663K |  
  | live555-latest-md5.txt | 2020-12-10 16:44 | 33 |  
  | live555-latest.tar.gz | 2020-12-10 16:44 | 663K |

Is it just me or are there no older live555 versions available to test?

nettings commented 3 years ago

not really related, but apparently this is not the only recent breakage due to live555 changes: #218 (already fixed by @mpromonet)

nettings commented 3 years ago

Ok, found this in their FAQ: 'To see which version of the code you currently have, look at the file "liveMedia/include/liveMedia_version.hh".' One may be excused for overlooking that one :o) My version is

define LIVEMEDIA_LIBRARY_VERSION_STRING "2020.12.11"

define LIVEMEDIA_LIBRARY_VERSION_INT 1607644800

Hi nettings,

live555 seems to change often of interface this days.... it doesnot even build with 2020.12.12. You can build it with :

cmake -D LIVE555URL=https://download.videolan.org/pub/contrib/live555/live.2020.12.11.tar.gz .

Best Regards, Michel.

Dear Michel, sorry to hear that - it must be a lot of extra work for you. Thank you for the workaround, that solves my problem! Maybe you should update your README.md to prevent other users from hitting this issue. All best, Jörn

OMG. They broke it again... Just posting this for your information, the workaround with the old live555 source works fine for me.

Hi nettings,

This is quite uncommon, usually live555 doesnot evolve much, it seems there is work in progress about IPV6. The approach of this project is to use latest version, often small refactoring vs big refactoring. Anyway you suggestion seems meaningful, I will add a note in the README to build with an oldest live555 release (even this release comes from videolan)

Best Regards, Michel.
