compilation instructions need updating?

[jevonlongdell]

Hi I'm using ubuntu 15.10 and I just tried to compile the source code using instructions at http://opencpn.org/ocpn/compiling_source_linux but these didn't work

It fails compiling a plugin. (see error message below)
According to https://github.com/nohal/chartdldr_pi it needs be be built "out of treee" I tried the instrions there but that failed too. (see error #2)

Error #1:
/home/XXX/progs/OpenCPN/plugins/chartdldr_pi/src/chartdldr_pi.cpp: In member function ‘virtual int chartdldr_pi::GetPlugInVersionMajor()’:
/home/XXX/progs/OpenCPN/plugins/chartdldr_pi/src/chartdldr_pi.cpp:219:12: error: ‘PLUGIN_VERSION_MAJOR’ was not declared in this scope
return PLUGIN_VERSION_MAJOR;
^
Error #2:
/home/XXX/progs/OpenCPN/plugins/chartdldr_pi/src/chartdldr_pi.h:53:25: fatal error: ocpn_plugin.h: No such file or directory

Works for me exactly as it should on the Ubuntu 15.10 (and all the packages on Launchpad built successfully just a few commits ago, so it is very unlikely that the build is broken).
Aren't you trying to build just the plugin instead of the whole OpenCPN tree in which it is included?
Ignore the out-of-tree build instructions from the original repository, they are irrelevant since the plugin was merged into the OpenCPN tree.
If you won't resolve it, attach the complete cmake and make output.

Thanks for your help. The problem went away when I made a fresh clone of the repository.

Not sure how I managed to get a non-functioning working copy according to git it was all synced up with this one. Not sure that it is worth looking into further but I attach the cmake output for the original (somehow broken) working copy.

Thanks for your help and sorry about the red herring.
