Bug#297948: vertex: FTBFS (amd64/gcc-4.0): invalid cast from type 'char' to type 'char'

[Andreas Jochens]

Package: vertex
Severity: normal
Tags: patch

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

c++ -c disk.cpp  -O2 -DHAVE_IMLIB `gtk-config --cflags`  -D__cplusplus 
-Dc_plusplus
disk.cpp: In function 'int ISPATHABSOLUTE(const char*)':
disk.cpp:133: error: invalid cast from type 'char' to type 'char'
disk.cpp:133: error: invalid cast from type 'char' to type 'char'
make[2]: *** [disk.o] Error 1
make[2]: Leaving directory `/vertex-0.1.14/vertex'

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

Regards
Andreas Jochens
