Minor break: I got a TIFFError redirected so now it finally prints: I get the following message when TIFFWriteScanline fails: "compression support is not configured" I can't se any issues in the configure output, but I will check again. Any ideas on how to configure compression support for LZW? 2010/8/23 Dennis Mølhom Hansen <molholm@gmail.com>: > Hi, > > The only flag I used for the built was --prefix.
