What COFF (windows .obj object file) viewers are available?

I am only aware of 2:

• dumpbin whi开发者_Go百科ch is included with Visual Studio
• PEView from http://wjradburn.com/software/

There is DbgHelp, but it's geared more toward the PE file rather than the object file. And Its intended to be used as an API rather than a tool.

the COFF format itself originated on unix https://en.wikipedia.org/wiki/COFF although Microsoft has extended the format somewhat and the unix seems to have abandoned that format in favor of ELF. But you might find some useful tools in the Unix world, for instance this dump tool from SCO http://docsrv.sco.com:507/en/man/html.CP/dump.CP.html

Just convert the COFF format to ELF and use some ELF viewer:

objcopy.exe --input-target=pe-i386 --output-target=elf32-i386 somefile.o somefile.elf

For example in Python you can then use this one-file-implementation, which only depends on the struct module: http://www.tinyos.net/tinyos-2.1.0/tools/platforms/msp430/pybsl/elf.py
