Nothing to do with ROOT, you must add this to the Windows System (or user) PATH environment variable.

[quote=“fine”][quote=“SBegun”]Hi there,
I am a beginner in ROOT and VC++.
How can I import classes like TStopwatch or TComplex from .dll libraries of ROOT
using VC++ 8.0 environment?
I need this to build .exe file of the project to speed up the calculation.
When I tried to use method with FARPROC pointer the message that TStopwatch is not a class or namespace appears.
Was these DLLs compiled without __declspec() options to classes?
Is the only way to compile the ROOT project with classes support under Windows to use Cygwin?
Where can I find the detailed instruction on how to do this?
Thanks a lot for future reply.[/quote]Did you try ACliC? (see: ftp://root.cern.ch/root/doc/7CINT.pdf page 93)[/quote]
Thank you.
I prefer use .EXE files. To compile .DLLs in ACliC I anyway need VC++ compiler installed.
Thus I would better make .EXE file by VC++ compiler.
Cheers, Sergij

I have added these PATHs. I have VC++ 8.0 compiler and the Totpr.dll is generated by ACLiC with Run Time Error R6034 in root.exe. Thus I would better prefer to make .EXE files and .DLL files directly by VC++ compiler.
Cheers, Sergij
In fact, there is no technical reason to choose the custom “exe” vs the DLL created by ACliC. The only “advantage” of your approach is the extra troubles 
you are encountering.

[/quote]Yes, it is correct.

Try some simple example.
- Create the C++ file “testStopWatchAccess.cxx”:
#include "TStopwatch.h"
void testStopWatchAccess()
{
TStopwatch a;
a.Print();
}2. Start the ROOT session by invoking root.exe
3. On ROOT prompt, type
.x testStopWatchAccess.cxx++At this point your small example should be compiled with your VC++, linked against of the appropriated ROOT DLL’s, loaded in the current ROOT session and executed.
[code]C:>root.exe -b -q -l testStopWatchAccess.cxx++

If that doesn’t work for you, this means you have some sort of the installation proble, REad the ROOT Manual andf then Seek the ROOT team / community assistance to fix your installation if any.

I have tried with the same result Run time error R6034.

Cheers, Sergij[/quote]Can you upload your Totpr to understand what we are speaking about. Mean time, can you try the example I had posted.

[/quote]The Run-time error R6034 indicates the problem with your original ROOT DLLs installation rather with root.exe or ACLiC.
Did you compile ROOT with VC++8.0 yourself?

ftp://root.cern.ch/root/root_v5.17.02.win32gdk.msi
[/quote]It was comlpiled with VC v.7.1 This can be source of R6034 error. Switchig to “exe” does not help you to get rid of that error. Can you try the ROOT compiled with VC++ v.8.0 instead from root.bnl.gov
It is “one click” installation. It should set the env automatically with no extra effort. Let me know as soon as you get any trouble. (May be you need to uninstall your 7.1 compiled ROOT first).

Sergij,
With Visual C++ 8.0, you should use one of the following:
ftp://root.cern.ch/root/root_v5.17.02.w … .debug.msi
ftp://root.cern.ch/root/root_v5.17.02.w … bug.tar.gz
ftp://root.cern.ch/root/root_v5.17.02.win32.vc80.msi
ftp://root.cern.ch/root/root_v5.17.02.win32.vc80.tar.gz
Cheers,
Bertrand.
Thank you.
Now I can use this option without errors.
With best regards.
