</span>In the g2clib makefile, there are some extra CFLAGS that may be forcing this error (“…Predefined bitmap applies…”). I was getting this error too, did some experimenting, and ended up with the third line below:<br>
<br>
#CFLAGS= -fPIC -O3 -g -m64 $(INC) $(DEFS) -D__64BIT__<br>
#CFLAGS= -fPIC -O3 -g -m64 $(INC) $(DEFS)<br>
CFLAGS= $(INC) $(DEFS)<br>
<span><br>
<br>
<br>

> Also added the 'U' flag to the ARFLAGS var so I didn't get a bunch of warnings about "deterministic mode" and the compilation went through without any errorst. The rest of the supplibs went fine except for dap/gadap which I don't really use.<br>

<br>
</span>It may be an issue related to the version of libpng your build is linking to. What do you from this:<br>
