Just files a support request for this:

Phenomenon: Using open source WinMerge as File Comparison utility for Source Control does not show differences.
  Running WinMerge by itself has no problems.


*Reproduce Steps:  Install WinMerge and specify it as the File Comparison Utility in the Source Control properties.  Select Show Difference from the System Tree; nothing displays.


Remarks:  WinMerge is an MDI application and it appears it is not allowed to become visible?  Or something.

Anyone have any experience with this?  Or suggestions as to what might be wrong?

Regards,

Phil

Hi Phil;

1) Did you try running the PB IDE "As Admin"?

2) Did you try WinDIFF instead (or any other file comparison utilities)?

Hi Phil, I use WinMerge successfully.

  • What version are you using?
  • What command-line is setup for WinMerge  in the workspace properties dialogue?

My gut feeling is your config (impacted by command-line arguments) is different.

Here are my WinMerge details:

  • WinMerge Version > 2.16.0.0
    • WinMerge folder NOT in my system path!
  • PowerBuilder version > 2019.R2.2203
  • PB Diff Viewer setup
    • Diff Tool > WinMerge 2.14.0.0
    • Executable > WinMergeU.exe
    • Path to EXE > C:\Program Files\WinMerge\WinMergU.exe
    • Arguments > -e -ub -dl %bname -dr %yname %base %mine

 Neither PB IDE nor WinMerge runs as Administrator. They both run as regular user.

Hi Phil,

make sure that your folders and files in your trunk directory are case-sensitive identical to the paths in your target file (.pbt). If anything differs by lower or upper case, WinMerge will not work properly.

 

Sincerely,

Marc

Hi Chris,

Thanks for jumping in.

I'm using this with our Source Control system, PowerVCS. It works with PBDelta without issues, so I think the configuration is right. WinDiff works fine. It's only WinMerge that I'm having trouble with, but as a reasonably well supported open source project, I would think it would work.

Tried running PB2019 as administrator and same result.

Hi Phil;

I see from your Support Ticket #3641, that calling the 64bit WinMERGE utility from the PB IDE worked!!!! :-)

Thanks for jumping in Michael,

I'm running WinMerge V2.16.4.0.

Command line in PB: "C:\Program Files (x86)\WinMerge\WinMergeU.exe" %s %s

WinDiff and PBDelta work without issue, so it's something about WinMerge.  But it is a well supported open-source tool and "one would think" it would work.  I have been trying to do this with the 32-bit version.  I'll try the 64-bit version, but I can't see why that would make a difference.

Phil

32 vs. 64 :: I can't see either.

Could you try and change the [ %s %s ] into [ %base %mine ] and see if that has any effect?

The plot thickens...The 64-bit version of WinMerge (same build) works as expected.

Bizarre! Anyways, you have a working setup now so maybe just accept that issue has been resolved?

Hello everyone. We're having this same issue with PB2019 R2 + WinMerge-2.16.8-x64. VM Workstations running Win10 Pro with latest upgrades. After editing any object (first check out, modify code, save changes) then right click -> Show differences, then WinMerge pops up and says files have no differences. Already tried running PB IDE as Admin but same result. I hope you can help us.

Regards
