VIPS,OpenSlide linker error

[Yusuf Roohani]

Hello,

First of all, I want to thank you guys for working on openslide. It’s a
really useful package. I’ve been having some trouble making VIPs link with
OpenSlide. I don’t have root privileges on my workstation so I install
everything into ‘~/.usr/local’.

I set the appropriate flags for the libraries, includes, pkg_configs etc.
when I had installed openslide, and everything went fine. The strange
thing is when I use the same flags to compile VIPS, I get the following
errors (shown below) when it links libopenslide.so. I even tried redo-ing
the VIPS installation without openslide and without libtiff, and it only
works if I don’t include openslide. So, I can use VIPS normally as long as
I don't link openslide, but I really need the .svs reading ability.

My hypothesis is that there’s something wrong with libopenslide.so and not
with the library paths, but what I don’t understand is why these errors
didn’t show up when I was building openslide. Do you guys have any ideas
about what I could be doing wrong?
