Description eroen 2012-10-09 17:20:13 UTC
The file `viewer/svutil.cpp` in the tarball fails to include the header `unistd.h`, but nonetheless uses functions defined therein. This causes a build failure on compilers that don't silently include the required header through any of the other headers that *are* included. gcc-4.7.2 shows this behaviour.

See https://bugs.gentoo.org/show_bug.cgi?id=413937 , upstream has not fixed it since that release. 

The file in question has not changed much since the tesseract-2.04-r1 release, and the old patch still has correct offsets. I suggest just applying that.
