Build fails on aarch64

[clort81]

gcc version 8.3.0 (Debian 8.3.0-26) aarch64

src/game/gamefontmap.cpp:99:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘char’ inside { } [-Wnarrowing] };

   {'}', 12,810, 52,106, -2,1, 54,        },
   {'~', 220,941, 79,42, -6,66, 89,       },
   { -1, 0, 0, 0, 0, 0, 0, 0              }

Is there a missing char in single quotes before -1?

[EDIT] Adding -Wno-narrowing to CXXFLAGS and CFLAGS in Makefile allows build to next error:

src/tools/profiling.cpp:21:5: error: impossible constraint in ‘asm’

Pulling out the asm (temporarily) and setting t=1; gets me an executeable: dynablaster: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1

But running I get segfault after title screen.

Unsigned int on arm is 32-bit, so dst[x] = (a << 24) | (r << 16) | (g << 8) | b should be fine.

The "optimized out" comes from -O2, compiling with -O0 yields

. This might be of some use for profiling later. Leaving here for notes. http://zhiyisun.github.io/2016/03/02/How-to-Use-Performance-Monitor-Unit-(PMU)-of-64-bit-ARMv8-A-in-Linux.html

Is the last problem something as simple as file not found? It doesn't look like your working directory is the game's root directory.
