|
|
|
Helpers to extract symbols from Unix libs and auto-generate
|
|
Windows definition files from them. Depends on nm(1). Tested
|
|
on Linux and Solaris only (-p option to nm is for Solaris only).
|
|
|
|
By Marc-Andre Lemburg, Aug 1998.
|
|
|
|
Additional notes: the output of nm is supposed to look like this:
|
|
|
|
acceler.o:
|
|
000001fd T PyGrammar_AddAccelerators
|
|
U PyGrammar_FindDFA
|
|
00000237 T PyGrammar_RemoveAccelerators
|
|
U _IO_stderr_
|
|
U exit
|
|
U fprintf
|
|
U free
|
|
U malloc
|
|
U printf
|
|
|
|
grammar1.o:
|
|
00000000 T PyGrammar_FindDFA
|
|
00000034 T PyGrammar_LabelRepr
|
|
U _PyParser_TokenNames
|
|
U abort
|
|
U printf
|
|
U sprintf
|
|
|
|
...
|
|
|
|
Even if this isn't the default output of your nm, there is generally an
|
|
option to produce this format (since it is the original v7 Unix format).
