Description alina 2014-01-09 12:08:00 UTC

There are several DCE tests and examples that are not validating the dependency with bld.env['SCTP_TOOLS_FOUND'] in the wscripts and will not compile without it. 

The simplest way to fix the problem is to install sctp-tools-dev. Is sctp-tools-dev a required dependency for DCE ? In this case, shouldn't the ./waf configure fail if it was not found?

Checking for header netinet/sctp.h               : not found

Static build                  : not enabled (option --enable-static not selected)

sctp-tools-dev                : not enabled (sctp-tools (netinet/sctp.h) not found)

The output from ./waf build gives the following error:

Comment 1 Hajime Tazaki 2014-01-09 18:26:07 UTC

thanks again.

the issue was fixed: if the sctp-tools-dev package wasn't found, it skipped two files built, but built socket factories, which don't use lksctp in fact.

I also added bake system deps check for the library.
