I have a netbsd-9 amd64 system on which I build packages from the stable branch, for use on other systems. I am using pkg_rr to update to each new branch and pick up scurity updates. My build was using the default jpeg, but I decided I wanted libjpeg-turbo. To effect this, I set JPEG_DEFAULT= libjpeg-turbo and then did "pkg_info jpeg" to see what depended on it, and found only tiff. So I did "pkg_delete -f jpeg" and then did "make replace" in tiff. ldd on tiff libs and bins showed it linking against libjpeg.8, and everything seemed fine. I then went to check things that depended on tiff. The lack of other things depending on jpeg directly seemed odd to me, but tiff's pkgconfig doesn't declare jpeg as a dependency. Various things actually did link with jpeg, and had a broken reference to libjpeg.9, e.g /usr/pkg/bin/dwebp. Building libwebp, I see that it includes mk/jpeg.buildlink3.mk, and the build log shows the type. libjpeg-turbo is buildlinked in, but it does not show up as a dependency in the package. If I turn off the tiff option, then libjpeg-turbo is still buildlinked in, but now it is a dependency. So, obviously I have to rebuild everything that should depend on libjpeg-turbo but does not, but why is the jpeg bl3 not recording a dependency? Could this be a general bug where including a bl3 file that has previously been recursively included doesn't record a dependency? Other ideas?
