Re: resource file handling ?


My failure to convert resource files to objects under NT persists.
Unfortunately, when I ran gunzip on your cvtres.exe.gz and
tried to run it, I got the same 'Not owner' message I get when
I link res2coeff objects.

Also, renaming .OBJ files to .o does not work. The gcc 'ld' loader
rejects it as an unidentified file type. I assume that files must
be COFF or ELF format. Unless there's another utility, this probably
will never work.

Are you running an NT system or Win95 ? As I mentioned, res2coff
produces .o files that link and run perfectly under Win95. Under my
NT 3.51 system, I get the 'Not owner' message. I still don't know
if the output is a truncated, as you suggest, or if there is some
API call in objimage.c that should be initialized with security
parameters. By the way, I compiled res2coff from the latest sources.

What I really want to do under NT is create an object file and link it.
That's why RCL wasn't really considered. I don't want an EXE or a DLL.
Any other ideas/clues ? I really need res2coff that works for NT...
