After creating an initial change to add checkAPI to CMake builds, following the current checks done by nmake, I got the attached (massaged) output.

 

CUSTOMBUILD : error : Found prohibited APIs in guid-utils.c: _snwprintf [C:\buildbot\builders\windows-x86-petri-dish\windows-x86-petri-dish\build\cmbuild\epan\checkAPI_epan.vcxproj]

Gerald (in r43756) said this should be StringCchPrintf().  Not sure why.

The Windows docs say the latter function is safer; change submitted.

Looks like these have snuck in while the buildbots weren't running checkapi; checkapis run from autotools also complains.

Actually, no, those have "always" been there; neither the nmake nor autotools checkapi ran in that directory.

There's a call to the checkapi target in ftypes in the main Makefile.nmake and in epan\ftypes\Makefile.nmake there is a checkapi target that does call checkAPIs.pl on the NONGENERATED_C_FILES, which from epan\ftypes\Makefile.common lists those files found to be at fault.

The first time I looked I just did "make -C epan/ftypes checkapis" which is what made me think it was a bug.  But the code there was ancient so I looked a bit more and eventually found that it's actually commented out in the top-level Makefile.{nmake,am}:

        cd ../ftypes
##      $(MAKE) /$(MAKEFLAGS) -f Makefile.nmake checkapi

I have no idea if the correct directories are being checked, as I said, I just followed what nmake did (mostly).

Agreed - just getting us to where we were would be good.

 

The other issue with CMake and checkAPIs is that CMake doesn't require enumerating header files, so there are no lists of files to feed to the script.  In the plugins I added a file(GLOB *.h) call to create such a list of headers for checking but didn't do that generally.  I guess there's a few spots where it could be useful.

I didn't even know we were checking header files...  I guess it makes sense though.
