Title: An easy one-- I hope.
Hi!
I think this should be a fairly easy question but for the life of me
I cannot find a solution. I have a Solaris 2.6 system that I have
built and installed several versions of libtiff in my attempt to
solve my woes. I am using GCC 2.8.1. The builds from source go
through without error and I have also tried the binary package for
Solaris 2.6 from the Solaris Freeware site. In both cases I am
running into problems with unresolved references on sqrt, log, and
exp when I attempt to use the library. We have some code which was
written using tiff-3.30 and we are attempting a recompile as we are
replacing a SPARC 1000 (Solaris 2.4) with an Enterprise 450. It's
not complicated code but I am having no end of difficulties. The
libtiff code section and a sample of the error messages are below.
Oddly enough I have been using several other libraries on the same
box (both shared and static) without difficulty. I know this post is
rather long but I am hoping this provides complete information. Any
assistance would greatly appreciated.
Here is a sample of the errors...
