I see various dump* utility commands, which have some
capability to emit symbols, in both .obj's and .exe's,
but they are within a hex core dump. Is their an equivalent
to MS's link -dump -symbols for .obj's and .exe's?
Also, how do I get symbols in a map file by invoking sc?

Ok, I now see -L/XREF and -L/DETAILEDMAP which I think addresses the latter. Still curious on the former, and for .obj's. -- Greg Comeau What's next: additional Windows backends and 'export'!

For .obj's: obj2asm file.obj For .exe's: dumpexe file.exe (all the symbols will be in there, as well as the hex data) > Also, how do I get symbols in a map file by invoking sc? sc file.c -L/map |

In the meantime I just ran libunres on a .obj and it seem to produce something meaningful, no? -- Greg Comeau What's next: additional Windows backends and 'export'!

In the meantime I just ran libunres on a .obj and it seem to produce something meaningful, no? I wrote libunres so long ago I don't remember if it works on .obj files! |

Any chance of making the utility newer than comdef's then? :) And also letting one output combo's of the different sections?
