how can i compile mame for 86X/32BIT system?

Hello to all the community, I am looking for someone who can help me or guide me to compile a version of mame 0.232 with the 86X/32BIT structure. I am using the compiler version "msys64-32-2019-03-25", apparently it comes by default to compile for the 64Bit system, but I still don't know how to compile for the 32Bit system, I have tried everything but I have failed I don't know if I need any special command to compile.

PTR64=0

 

PTR64=0

 So I don't know what I'm doing wrong

I use this command

make PTR64=1 SUBTARGET=arcade OSD=winui STRIP_SYMBOLS=1

------------------------------------------------------------------------------------------------

It gives me an error

makefile:1141: *** MINGW32 is not set.  Stop.

Retro Danuart already compiled 32-Bit-Versions: https://www.retroroms.info/forum/topic/32-bit-Mame-and-other-distributions-executables.htm

You need to set the MINGW32 variable, for example (at the command prompt or in your build batch file)

set MINGW32=E:\Mingw\5-3-0\mingw32  (back when I used to build 32-bit with GCC 5.3)

You need to determine where your 32-bit mingw is and set the MINGW32 variable as appropriate.

I ended up giving up, still not able to compile 86X,

thank you very much for all your help

I will keep compiling 64X
