Right now the check for the presence of hunspell.hxx in
ConfigureChecks.cmake always fails for me (MacOS10.14, master build)
with the result `HAVE_HUNSPELL_CXXABI = FALSE`, although hunspell.hxx is
available. That's a minor issue since hunspell works anyway, but the
check seems useless now.
Where is it available? Here, on ubuntu, it is under
/usr/include/hunspell/hunspell.hxx
I use the macports one /opt/local/include/hunspell
but it also works with the 3thparty one included with lyx.
To proceed the check should include a `LINK_LIBRARIES` entry in the
try_compile() step.
No, not needed, see below ...
Also the `hunspell` in the `#include
<hunspell/hunspell.hxx>` instruction in the test file should be removed.
It should be included in the `HUNSPELL_INCLUDE_DIR` definition.
Good point.
With these changes `HAVE_HUNSPELL_CXXABI = TRUE` (supposed hunspell.hxx
is present).
I don't understand the
"-DCMAKE_CXX_LINK_EXECUTABLE='${CMAKE_COMMAND} echo not linking now...'"
entry which contained a typo anyway. It sounds like one wanted to avoid
the linking in which case the LINK_LIBRARIES is indeed not needed.
The try_compile() normally creates an executable (e.g. compile + link)
and we want to compile only here.
I thought so (and I suppose libhunspell is then also not needed by LyX,
which I did not realize), but that doesn't work for me; without the
LINK_LIBRARIES the build fails:
Undefined symbols for architecture x86_64:

It has been reported that this trick does not work with XCode:
