I believe I made some headway on this issue. I notice that in the SharedLibraryFromObjects rule, there is this bit of code:

rule SharedLibraryFromObjects TARGET : OBJECTS : OPTIONS
{
   ...
  local linkRule = Link ;

  if $(COMPILER) in vs2005 vs2008 {
        if nomanifest in $(OPTIONS) {
            linkRule = LinkNoManifest ;
        } else if $(CONFIG) = debug {
            linkRule = LinkDebug ;
        }
    }

    $(linkRule) $(_linkTargets) : $(_s) ;

However, for the ApplicationFromObjects rule, there is no such check, and always the regular Link rule is used:

rule ApplicationFromObjects TARGET : OBJECTS : OPTIONS
{
 ...
  Link $(_linkTargets) : $(_s) ;

If I change Link to LinkDebug the incremental linking problem goes away. It seems the regular Link rule invokes the mt.exe tool which disturbes the exe such that incremental linking doesn't work. LinkDebug works around this. Can anyone comment on this? Thanks.

One more question, in the LinkDebug action, I can't determine the purpose of these lines:

if exist $(MANIFEST).intermediate.manifest "$(MT:\\)" -nologo -notify_update -manifest $(MANIFEST).intermediate.manifest -out:$(MANIFEST).embed.manifest &
    if "%ERRORLEVEL%" == "1090650113" echo $(MANIFEST_TYPE) 24 "$(MANIFEST).embed.manifest" > "$(MANIFEST).embed.rc" &
    "$(RC:\\)" /fo $(MANIFEST).embed.res $(MANIFEST).embed.rc &
    "$(LINK:\\)" /nologo /out:$(<[1]) $(UNDEFS) @@($(LINKFLAGS) $(>) $(NEEDLIBS:T) "$(LINKLIBS)")

I removed them and got linking just fine, are they needed? Also, is the ampersand at the end of the line used for anything? Thanks for the info.

I apologize for the late response. I had a number of issues come up last week that took me away from the computer.

The SharedLibraryFromObjects implementation is correct. I have made the same change to ApplicationFromObjects, as per your suggestion. It isn't checked in yet, but it will be soon. This was a terrible oversight, but given I've mostly been working with DLLs lately, it isn't surprising.

As far as the LinkDebug action goes, the complex action you posted above is necessary to allow the incremental linking of the executable with an embedded manifest. You can read more about it here: http://msdn.microsoft.com/en-us/library/ms235591%28VS.80%29.aspx

The ampersand at the end of the line runs all of the lines in the same DOS command. I believe it is necessary for proper errorlevel propagation.

No problem, I understand life happens. Thanks for the explanations, that makes sense.

BTW, this is fixed in JamPlus 0.4.
