I'm trying to avoid removing the $linklib statement, but currently it's the only way to build the i386-win32 compiler on my 64-bit system.  I'm suggesting turning the error into a warning, if the correct DLL can't be found, because it doesn't affect successful compilation of the unit.

Of course, being able to locate the correct 32-bit DLL or some such is better overall, although I would still propose a warning over an error.

Hi everyone,

I have a slightly annoying error when building the compiler for i386-win32.  I mentioned it to Sven a while ago, and the cause is due to the fact that my copy of common.dll is 64-bit, not 32-bit (as Sven confirmed for me).

Compiling .\oracle\src\oraoci.pp
oraoci.pp(1437) Error: Invalid DLL C:\WINDOWS\system32\common.dll, invalid header size
oraoci.pp(1437) Fatal: There were 1 errors compiling module, stopping
Fatal: Compilation aborted

Simply commenting out "{$linklib common}" on line 19 of the above file fixes the problem.  I would like to propose that this error be changed to a warning, since apparently not having the library present doesn't cause issues for compilation, just possibly execution later on.

No. If you have a messed up system, that is not *our* fault.

But isn’t the complaint valid to a certain degree: if one cross compiles from x86_64-win64 to i386-win32, then the wrong DLLs are checked due to folder redirection, no? We have only code in place for the other direction (i386-win32 to x86_64-win64).

The weird behaviour of windows is is not a valid reason to remove a {$linklib} statement.

Michael.
