merging .dll files with ILMerge failing to work

Question

First of all, I'm not sure if this is a problem with ILMerge or not, but I can't merge.dll files into my application. I tried this on the command line:

ilmerge /target:winexe /out:test.exe MyApp.exe lib1.dll lib2.dll lib3.dll

I got the following error, and I have no idea what it means:

There were errors reported in MyApp's metadata. The pdb associated with D:\C#\source\bin\ReleaseMyApp.exe is out of date.

I'm using the latest version by the way (2.10.526.0), but yeah I can't get this to work and I really need some help. What does the above error mean and how can I fix it?

Answer 1

The pdb associated with D:\C#\source\bin\ReleaseMyApp.exe is out of date.

Since you haven't explicitly said that you have checked the pdb and exes are in sync, I guess I'll ask the obvious question - Is there a pdb in the folder and have you checked the timestamps on the files?

As I understand it, if there is debug info available for the source files, then ilmerge will create debug information for the target and if the original is out-of-date, then it probably displays this error rather than generate incorrect information.

If you don't need the debug information, what happens if you delete the pdb files?
