Okay net wizards, I need some advice as to how dangerous a path I am
trodding...
I am developing an application with Zortech's C++ v2.0. I need to link
with a 3rd party library which was built with MS C v5.0. My link line looks
like the following:
link test,,,fg+pll+zll+cpptl+(3rd party library)+llibc7 /NOD/NOE;
^^^^^^^^^^^^^^^^ ^^^^^
Zortech libs MS lib
The program links with 14 multiply defined symbols and 2 fixup overflows as
shown at the end of this message. The resulting executable runs fine
however, in spite of the linker errors. My simple test program uses all
the functions my full-blown application will use. Should I continue on
developing my application and just ignore these linker errors, or should
I be concerned that later down the road something might break????
Linker errors:
LLIBC7.LIB(CRT0) : error L2025: __acrtused : symbol defined more than once
LLIBC7.LIB(CRT0DAT) : error L2025: _errno : symbol defined more than once
.

I recommend that you call the vendor of the 3rd party library and request
that they send you a Zortech version.gb7@prism.gatech.EDU (Joe Bradley) (03/29/90)

I tried that but they said they only support MS C or MS Quickbasic. They don't sell the source code either. -- G.J.

About a year and a half ago, we bought Watcom C. One of the great features was we could set up calling conventions to be compatible with any existing C library. Unfortunately, that was only if you didn't link with the Watcom library. I called and asked about this, because we too have to link with existing 3rd party libraries built with MSC. The response from Watcom was 'Call the vendor of the 3rd party library and request that they send you a Watcom version'. Our response was to send Watcom C back, and continue using MSC. Walter, I own Zortech C++ v2.0. Actually, it's now 2.06 after waiting two months for Zortech to to upgrade me, and finally having to call them. But I can't use it, because we still have to link with existing 3rd party libraries built with MSC. So I guess we'll look into buying Intek or Guidelines C++. Too bad, because I like Zortech.

You can buy the sources to Microsoft's library. If you own MSC, they charge $150. Most are assembler. You'd might have to write a filter to change from one assembler syntax/pseudo-ops to the other, but you could then have the MSC functions in you object format. kdq -- Kevin D.
