Building Hugin with debugging symbols

[Greg 'groggy' Lehey]

As you may have noticed, I'm currently having difficulty with the 64
bit version of Hugin under FreeBSD. I'd like to look around inside
with gdb, but I don't do cmake, and I can't work out how to compile
with debugging symbols. Can anybody help? It would also be
interesting to be able to specify which compiler to use.

A quick snoop about makes me think that if you use cmake like this it will
include the debug...

" cmake -DDebug=1"

without the "" of course and prepending with ./ if necessary.
I might have this wrong, as I'm no expert on cmake (or anything else for
that matter), but this looks to be the way cmake is invoked from within
the Fedora rpmbuild spec file.

Don't know about that one.

Whoops...that's not right. If building in the topmost dir of a hugin
repository, and running cmake at that level;

" cmake . -DDebug=1"

It should be "cmake -DCMAKE_BUILD_TYPE=Debug"

Yes, you are right.
Sorry, I should have checked the CMakeLists.txt for the specific
definition and not assumed it would be as per the one example in my
rpmbuild spec file.

Thanks, but that's not what I'm looking for. That enables debugging
code in the source. I'm looking for something that tells the
Makefiles to build the object files with debugging symbols (the -g
option to gcc) so that I can investigate what's going on with gdb.

This option passes the -g compiler option automatically, so you will
get debugging symbols. This is the standard way to create a debug
build using CMake. If you really do not want other debug information,
just set up CFLAGS & CXXFLAGS appropriately before running cmake. Oh,
and for both options to work you need to do a clean build (especially
there must not be a CMakeCache file before you run cmake).
