I have succeeded in getting both Tcl 8.0.5 and TclBlend 1.2.3 built with debugging info. Unfortunately, I still get a crash as soon as the tclblend.dll is loaded. I turned on the debug flag in pkgIndex.tcl and everything seems in order. I noticed a link warning associated with the tclblend.dll build as shown: set LIB=E:\VS6.0\VC98\lib E:\VS6.0\VC98\bin\link.exe /debug:full /debugtype:cv /NODEFAULTLIB /RELEASE /NOLOGO /align:0x1000 /MACHINE:IX86 /entry:_DllMainCRTStartup@12 /dll /out:tclblend.dll E:\Tcl\Tcl8.0.5\src\win\Debug\tcl80d.lib E:\java\sun\jdk1.2.2\lib\jvm.lib msvcrtd.lib oldnames.lib kernel32.lib advapi32.lib user32.lib gdi32.lib comdlg32.lib winspool.lib @C:\TEMP\nma00176. LINK : warning LNK4108: /ALIGN specified without /DRIVER or /VXD; image may not run Creating library tclblend.lib and object tclblend.exp I don't know if this warning can be ignored, but putting the /driver flag in the link should not and did not solve the crashing problem and I can't imagine how the /vxd flag would help. I am quite new to Visual Studio and do not quite know how to set up debugging so that I can walk through the source code. I was able to attach to the running tclsh80d process, but this only provides a disassembly which is pretty much useless to me. I also tried to create a project from the makefile, but this only created a project that contained one file --- the makefile --- which was also useless. I assume that you can debug the dll and trace into its source and probably trace into tcl 8.0.5 source as well. Is there some way that I can set up Visual Studio so that I can debug Tcl 8.0.5 and the TclBlend dll using the source without having to build a project by hand? If it does have to be done by hand, does some kind soul have a project for Visual Studio 5 or 6 that they can send to me? -=> Gregg <=- ---------------------------------------------------------------- The TclJava mailing list is sponsored by WebNet Technologies.
