Hi folks

Last week I was happily debugging my C DLL tcl extension using Visual
Studio. Today tclsh85 refuses to load the extension generating an
alert dialog quoting an R6034 run-time error. If I recompile the
extension as a Release rather than Debug I can load and use the DLL as
normal. I'm mystified.

Has anyone else encountered this (it seems to do with M$ manifest
files) and can suggest a way forward? Tomorrow, I plan to rebuild Tcl/
Tk etc from source with Debug on (I am currently using ActiveTcl
8.5.8) and see if that helps - I really do need to debug my extension :
( Not sure if this will help as it all worked on Friday!!! I am
suspicious that the M$ Debug run-time libraries are not being
found....


kind regards
Julian

You can try dependency walker, to see if your system finds all the
required DLLs (i.e. the debug ones of Visual Studio).

Thanks Georgios

A combination of your dependency walker suggestion and the advice in
http://www.insidercoding.com/post/2008/07/21/Debugging-issues-with-MSVCR90DLL.aspx
(found via the wonderful http://stackoverflow.com/) led me to discover
that MSVCR90.dll and MSVCR90D.dll were being linked. I told VS2008 to
ignore the former and all is now working.

Still mystified why this happened in the first place but happy now
that I can get on debugging

kind regards
Julian
