1. PDB format supports incremental linking. I have not tested whether<br>
&gt; [snip]<br>&gt; 3. <br><br>Good points. So basically you create an individual .PDB file for each source file with exception of lib.exe case. The lib.exe case worries me a bit.<br><br>How doe sthe compiler finds all generated PDBs? Does .OBJ file have the path to PDB encoded into it?<br>
<br>Actually why do we need a PDB file to be generated for .LIB? LIB is just a bunch of OBJ files glued together. Passing LIB to the compiler is almost the same thing as passing the list of OBJ files. I would think that cl.exe should be able to find PDB files in both cases.<br>
