Bug#294243: evince: FTBFS (amd64/gcc-4.0): cast from 'DviLib::DviFontMap*' to 'int' loses precision

[Andreas Jochens]

Package: evince
Severity: normal
Tags: patch

When building 'evince' on amd64 with gcc-4.0,
I get the following error:

Making all in dvilib
make[4]: Entering directory `/evince-0.1.3/dvi/dvilib'
if g++ -DHAVE_CONFIG_H -I. -I. -I../..     -g -Wall -O2 -MT dl-dvi-file.o -MD 
-MP -MF ".deps/dl-dvi-file.Tpo" \
  -c -o dl-dvi-file.o `test -f 'dl-dvi-file.cc' || echo './'`dl-dvi-file.cc; \
then mv -f ".deps/dl-dvi-file.Tpo" ".deps/dl-dvi-file.Po"; \
else rm -f ".deps/dl-dvi-file.Tpo"; exit 1; \

dl-dvi-file.hh:40: error: cast from 'DviLib::DviFontMap*' to 'int' loses

make[4]: *** [dl-dvi-file.o] Error 1
make[4]: Leaving directory `/evince-0.1.3/dvi/dvilib'

With the attached patch 'evince' can be compiled
on amd64 using gcc-4.0.
