Hi *,

are supported in -Fu (unit search path) networks paths? i.e. -Fu\\server\share -Fu\\server\share\path ?
When I am compiling project, which is located on local drive, but uses units from network, error is raised while compiling project file .lpr "Cannot find XYZ used by ..."
(when I map network path to drive letter then it works as expected)

TIA

Hi *, are supported in -Fu (unit search path) networks paths? i.e. -Fu\\server\share -Fu\\server\share\path ?

Correction: unit cannot be found only if it is placed in "share root" \\server\share !
When is placed in \\server\share\path then it is found.

Why?

Addition:

when I use in *uses* clause:

use unit1 in '\\server\share\unit1.pas'

then *it works* also when I omit search path from -Fu (no search paths specified in Project Options)

strange, does not?

Possibly Share vs directory.   A directory has 4 slashes (\\x\y\<something), a share two.

Try \\server\share\.

Note that probably none of this is supported, just coincidence because Windows functions interpret it themselves.

*Does not works. More confusing is that, when I map \\server\share to F:\ and I add F:\ to search path it does not work also! *

*(if unit is in any subdirectory i.e. F:\something then it works ... so only root does not work!)*

*But how to explain cause with F:\ ?*

[0.015] Handling option "-Fud:\"
[0.015] interpreting option "-Fud:\"
[0.015] Path "D:\" not found

So the path exist function probably fails on root dirs.

I never knew "in" even existed! This totally blows my mind. Was it something added from Delphi that I never heard about?

Since the very first versions of Delphi.

This looks like the infamous wrong implementation of checking of directory existence based on reading its attributes (which doesn't work for the root directory, because it has no specific entry on the file-system and thus also no attributes, at least on DOS-like systems) without special handling of the special case of the root directory:

cfileutl.pas, line 361-375 (trunk):

     function TCachedDirectory.DirectoryExists(const
AName:TCmdStr):boolean;
       var
         Attr : Longint;
       begin
         if not TryUseCache then
           begin
             Result:=PathExists(Name+AName,false);
             exit;
           end;
         Attr:=GetItemAttr(AName);
         if Attr0 then
           Result:=((Attr and faDirectory)=faDirectory)
         else
           Result:=false;
       end;

I suggest filing a bug report.
