SOLVED - help editing SDL_config.h to get DOSbox working
so I was able to compile the latest dosbox 0.74-2 via this environment:



Code:
# needed beta/neko_gmp11-5.0.2-p1.tardist
# needed libFLAC from freeware
# final link line needs -lgen after dos/libdos.a 

export CC=gcc
export CXX=g++
export CFLAGS=" -g0 -O2 -mips4"
export CXXFLAGS="-g0 -O2 -mips4"
export CPPFLAGS="-I/usr/nekoware/include/SDL"
export LDFLAGS=""
export LD_LIBRARYN32_PATH=/usr/nekoware/lib
#export ac_ct_CXX=g++

./configure -prefix=/usr/local
gmake 

the issue is dosbox dies because (dummy) CDROM support isn't configured by default:


Code:
-bash-4.2$ ./dosbox
DOSBox version 0.74-2
Copyright 2002-2018 DOSBox Team, published under GNU GPL.
---
Exit to error: Can't init SDL SDL not built with cdrom support

-bash-4.2$ 

reading up on this issue via:

https://web.archive.org/web/201412152142...ox_on_irix

it appears I need to edit the SDL_config.h file to add dummy CDROM support, I've been trying multiple things, but I can't seem to figure out the right edits.  Here are a few I tried:


Code:
-bash-4.2$ grep dosbox /usr/nekoware/include/SDL/SDL_config.h
#define SDL_CDROM_DISABLED 0 /* # Disabled to compile dosbox */
/* #undef SDL_CDROM_DUMMY /* uncomment for dosbox */
#define SDL_CDROM_DUMMY 1 /* added for dosbox */
-bash-4.2$ 


Does anyone have an idea what I'm doing wrong?

RE: help editing SDL_config.h to get DOSbox working
ok so I got the gcc build working.  

https://imgur.com/eNpOAl2

I edited "src/gui/sdlmain.cpp" and changed:

Code:
if ( SDL_Init( SDL_INIT_AUDIO|SDL_INIT_VIDEO | /*SDL_INIT_TIMER |*/ SDL_INIT_CDROM
to:

Code:
if ( SDL_Init( SDL_INIT_AUDIO|SDL_INIT_VIDEO //| /*SDL_INIT_TIMER |*/ SDL_INIT_CDROM

It seems cdrom support works fine in dosbox, it was just not getting initialized in SDL, but I wasn't able to trace back the root cause of the problem.
one important note is that in the "dosbox-0.74-2.conf" file, the keyboard mapping is screwed up by default, I had to set

Code:
usescancodes=false


Now on to the MIPSpro build...

RE: help editing SDL_config.h to get DOSbox working
I'm having some problems with the MIPSpro build - I have to admit I don't have much C++ experience on IRIX, so this might be a very basic issue I hope.

Anyway here are my notes to  compile with MIPSpro:

Code:
-line 43 in src/cpu/cpu.cpp change "#define CPU_LOG(...)" to "#define CPU_LOG"
-line 33 in /include/ipx.h  change "#define LOG_IPX(...)" to "#define LOG_IPX"

-define and undefine __c99 in src/hardware/mame/emu.h:

 #include "dosbox.h"
 #if defined(_MSC_VER) && (_MSC_VER  <= 1500)
 #include <SDL.h>
 #else
-#if defined(__sgi)
-#define __c99
-#endif
 #include <stdint.h>
-#if defined(__sgi)
-#undef __c99
-#endif
 #endif
 #include <math.h>
 #include <float.h>
 #include <stdlib.h>
 #include <memory.h>

-after the #includes in src/dos/cdrom_image.cpp, add:
 #if defined(__sgi) || defined(_sgi_)
   long int lround(double x);
 #endif

I compiled using this env:

Code:
export CC=cc
export CXX=CC
export CFLAGS="-c99 -g0 -O2 -mips4"
export CXXFLAGS="-g0 -O2 -mips4"
export CPPFLAGS="-I/usr/nekoware/include/SDL"
export LDFLAGS=""
export LD_LIBRARYN32_PATH=/usr/nekoware/lib


./configure -prefix=/usr/local
gmake 

I also tried this:

Code:
export CC=cc
export CXX=CC
export CFLAGS="-c99 -g0 -O2 -mips4"
export CXXFLAGS="-g0 -woff all -O2 -mips4"
export CPPFLAGS="-I/usr/local/include -I/usr/nekoware/include"
export LDFLAGS=" -L/usr/local/lib -L/usr/local/lib32 -L/usr/nekoware/lib -L/usr/freeware/lib32"
export LD_LIBRARYN32_PATH=/usr/local/lib:/usr/local/lib32:/usr/nekoware/lib:/usr/freeware/lib32

./configure -prefix=/usr/local
gmake 

both gave me a long list of link errors,  which I can't really make heads or tails out of:

RE: SOLVED - help editing SDL_config.h to get DOSbox working
turns out the issue is the makefiles assume your using "ar cru" for lib archiving, the makefiles had to be edited manually with AR=CC and ARFLAGS="-ar -o"

The MIPSpro build doesn't actually work correctly, the dos command "mount" gets broken somehow, but I will play some more and create a new thread about when I do some more poking around
