ImportError: No module named dwarf4

[zwilcox]

I'm getting the following error when running ghidra2dwarf:

Traceback (most recent call last):
  File "/home/_____/ghidra2dwarf/ghidra2dwarf.py", line 22, in <module>
    from ghidra.app.util.bin.format.dwarf4.next import DWARFRegisterMappingsManager
ImportError: No module named dwarf4

It runs after I manually changed it to:

from ghidra.app.util.bin.format.dwarf

ghidra2dwarf.py> Running...
Decompiling function 0: _init
Decompiling function 1: entry
Decompiling function 2: __lshrdi3

...

Just incase any of this matters:

maybe it can be changed to the following to support both ways?

def importDWARFRegisterMappingsManager():
    try:
        from ghidra.app.util.bin.format.dwarf import DWARFRegisterMappingsManager
        return
    except ImportError:
        pass
    try: 
        from ghidra.app.util.bin.format.dwarf4.next import DWARFRegisterMappingsManager
    except ImportError:
        print('Unable to import DWARFRegisterMappingsManager')

I was getting the same

ghidra2dwarf.py> Running...
Traceback (most recent call last):
  File "/home/chase/install/ghidra2dwarf/ghidra2dwarf.py", line 23, in <module>
    from ghidra.app.util.bin.format.dwarf4 import DWARFRegisterMappingsManager
ImportError: No module named dwarf4
ghidra2dwarf.py> Finished!

I was able to put this in and it worked

# from ghidra.app.util.bin.format.dwarf4.next import DWARFRegisterMappingsManager
from ghidra.app.util.bin.format.dwarf import DWARFRegisterMappingsManager
def importDWARFRegisterMappingsManager():
    try:
        from ghidra.app.util.bin.format.dwarf import DWARFRegisterMappingsManager
        return
    except ImportError:
        pass
    try: 
        from ghidra.app.util.bin.format.dwarf4.next import DWARFRegisterMappingsManager
    except ImportError:
        print('Unable to import DWARFRegisterMappingsManager')

Pro tip just don't use dwarf 4
