vips-7.26.3 # ./configure --help --enable-cxx build C++ components (default: test) Also, media-gfx/nip2 does not link against libvipsCC.so, so I suggest adding a "regular" cxx USE-flag (i.e., IUSE="cxx" and not IUSE="+cxx").
Ping?
In newer versions (not yet in portage), there is no longer the configure option and the C++ dependency seems to be hard.
