Error linking gnatcom: cannot find -lole32

[Vincent Smeets]

Hallo,

I have installed GNAT 3.15p on my Windows98 system. Now I want to use GNATCOM and GWindows. At compiling GNATCOM, I got an error from the linker. It can't find the library ole32. What am I missing? Am I missing some required software or do I have to use an additional option for the linker?

Thanks,
Vincent

Re: Error linking gnatcom: cannot find -lole32

[svaa]

I have the same problem with W2k. I have those versions and gnat
3.15p.

The problem is in these lines in reggnatcom.ads

pragma Linker_Options ("-lole32");
pragma Linker_Options ("-loleaut32");

it can't find the lib ole32.dll, but it exists and is in
c:\windows\sytem32\ole32.dll. I don't know with it doesn't find it.
I've supposed that it looks for libole32.o or libole32.a or it has
something to do with directories. I've tried

   pragma Linker_options ("--dll-search-prefix=c:/windows/system32/");
   pragma Linker_Options ("-Lc:\windows\system32\");

and lot of things. But it doesn't works neither. Perhaps there is some
problem with my special configuration, W2k usually has the system
files in c:\winnt not in c:\windows.

It's just speculation, I don't have the first idea and I don't know
what else try.

The linker option "-lole32" tells the linker to look for "libole32.a",
not "libole32.dll". "libole32.dll" is needed at run-time, but
"libole32.a" is needed at link time.

libole32.a is from the "extra" Windows GNAT installation file
"gnatwin-3.15p.exe"; make sure you install that. It puts "libole32.a"
in GNAT/lib/win32; gnatlink should look there automatically.

Hallo again,

I have found the answer myself.

I have only installed gnat-3.15p-nt.exe and not gnatwin-3.15p.exe. After installing gnatwin, I could compile gnatcom without problems.
