Installation of p20-emu

[Note]

Note

During extraction, you may get the following message(s): 

unzip: Cannot set mode for '...': Operation not supported

You may ignore said message(s), everything is fine. It is caused by an attempt to set the file attributes on a symbolic link, which are ignored on most Unix and Unix-like systems, a notable exception being macOS.

Apply a patch to build without any debugging information, which allows for a slightly faster binary: 

patch -Np1 -i ../p20-emu-d75a83-no-debug.patch

Optionally, apply a patch to search for the ROMs in a system-wide location and not the current directory: 

patch -Np1 -i ../p20-emu-d75a83-system-roms.patch

Install p20-emu by running the following command: 

make Musashi/m68kops.h &&
make

Now, as the root user: 

install -v -Dm755 emu /usr/bin/p20-emu

If you have applied the systemwide ROMs patch, install those ROMs as the root user: 

install -v -m755 -d /usr/share/p20-emu &&
install -v -m644 ../U15-MERGED.BIN /usr/share/p20-emu &&
install -v -m644 ../U17-MERGED.BIN /usr/share/p20-emu

Command Explanations

make Musashi/m68kops.h: This command explicitly generates a header file used during build time to avoid a race condition.
