[GAP Forum] Error message when compiling gap development version

[Gábor Horváth]

Hi Max,

Indeed, installing zlib1g-dev fixed the problem.

This was a package I installed on the other machine, because this was 
needed to compile some other stuff, so that explains the difference 
between the behavious of the two machines, as well.

Thanks for the help,
Gabor
