I have a couple of C LIB files, and respective header files.
I need to make use of these from Delphi.
 
The only way I can figure is to build .OBJ object files, and include them in my app.
Now my problem is...HOW ?

Some-one mentioned to me I should use PLINK, apparantly a feature which was supplied as part of dos 3.x
 
However, I would assume the .LIBs are 32 bit, as they have been developed for NT use only.
 
Since my knowledge of C is limited, and the LIBs contain MANY calls, I don't want to go through the excersize of developing a DLL, in C, unless it's my last option.

What now ???

Delphi uses libraries for accessing to databases. It uses idapi.lib or idapi32.lib in Delphi 2. You should have a BDE.INT somewhere in your Delphi directories. It's a sample of IDAPI.H translated to Delphi pascal. If you installed sources to you have all the sources for database components, which uses idapi.lib.

In Project Options/Library/Library Path you should set a path to your libraries.

I tnink this examples should help you. I didn't have enough time to try to make an example of using a library. Let me know if you had some success. If not write back and I'll try to make an example.

Thanks for the reply. However, the idapi lib is actually a DLL.
The file formats I have are *.LIB. I performed a search in the
Borland dirs for IDAPI*, and found only DLLs.

I am using a full blown version of Delphi 2.1 (w/src), and
am led to believe I have all borland want me to...

Project Options/Library... I assume you are explaining a menu
selection...  No such menu option

Project/Options supplies a dialog, with no indication to defining
library paths. I checked out Tools/Options/Library, but as far as I can tell, this only points to Delphi style libraries (.DCU).

Once again, thanks for the answer. Perhaps you could elaborate a little more. I feel though, that I will need to develop a DLL from C anyways, which can then be used from Delphi.

Hope to hear from you soon
