By default, when using &lt;debug-symbols&gt;on/&lt;debug-store&gt;database (msvc compiler option /Zi) for external debug databases,<br><br>This is pretty interesting. I never used &quot;&lt;debug-store&gt;database&quot; option yet I was always getting correctly named PDB files. I guess this is because when debug symbols are enabled via just &quot;&lt;debug-symbols&gt;on&quot;, the compiler gets &quot;/Z7&quot; option. I.e. it adds debug information to the .obj file itself. Once it is done the linker is able to generate correctly named .PDB file.<br>
<br>Is there any particular reason why you need /Zi to be used and not /Z7? Are you doing something special?<br><br>-- <br>Best regards,<br>  Alexey Pakhunov.<br>
