[Insight-users] Re: volview plugin DLL post-build error (clarification)

[mrcheung at mdanderson.org]

Hi,

I found out that if I copy the DLL to the Volview plugin folder on the same
machine that I generated the DLL, volview can see the DLL (despite the
post-build errors).

Now, if I copy the same DLL to the Volview plugin folder on another
machine, then the volview cannot see it. I also checked that for the
Volview running on this second machine can see other plugins fine.

I would appreciate any help. This is problem for me because the plugins
would not be portable then.

Hi,

I am testing making volview plugin. I used a plugin already available and
build it. Got this error, although a DLL file was generated. When I
manually copy the DLL file generated this way into the Volview Plugin
folder, the Volview does not seem to see it. Any help is appreciated.

Rex

My Cmake setting:
Where is the source code: C:\Insight2\InsightApplications
Where to build the binaries: C:\Insight2\InsightApplications-VSNET
ITK_Dir: C:\Insight2\insight-vc++
Volview_Binary_Dir:C:\Insight2\InsightApplications-VSNET\VolviewPlugIns


Rex:

The specification of VolView_BINARY_DIR is incorrect. This is supposed to
refer to the binary directory where VolView.exe is present. This is why you
get an error from the PostBuild copy process. There is no "Plugins"
directory in InsightApplications. The PostBuild Copy is meant to copy the
DLL for you to VolV I would suggest that you simply wipe this cache entry
out. (You can do that by rightclicking on this cache entry and selecting
Delete).

In any case, VolView should've been able to load the DLL if you dropped it
into its Plugins folder. Could you please verify if you dropped it in the
right place as shown below.

VolView.exe
