Re: [open-cobol-list] calling std c library calls from cobol and cob_inspect_tallying() segmentation violation

[Richard A. Painter]

i am using 0.9.5.91...

when i do "cobc --help" it reports that the -m means "build a dynamic-linking
module".  from what you say this must be wrong.

1. this version does NOT produce a .so file!  i'm certain 0.9.5 release did
produce .so by default and a .o when using -static.  i did not run the test i
have run here on the released version.

2. what does the following really mean?
XMLINPUT.cob:221: warning: compiled as a module due to USING clause
XMLINPUT.cob:221: warning: use compiler option `-m' explicitly

it seems that the warning says the module compile mode was used BECAUSE it had a
USING, not because it had no main().

3. yes, i do have PROCEDURE DIVISION USING and when i cobc i get the following
results.  when i use the -m the 2-line warning goes away.  however, i never get
the .so for the dynamic:
