Hi,
I have a CMake script that runs on Windows with MinGW Makefiles that
builds the install target OK. It is a Qt GUI application and uses
BundleUtilities::fixup_bundle to pull in and link/rpath prerequisites.
When I build the package target with an NSIS packager it looks like
the fixup_bundle stage breaks in some way. I get several of the
following message box pop up in the install phase.
---------------------------
link.exe - System Error
---------------------------
The program can't start because mspdb80.dll is missing from your
computer. Try reinstalling the program to fix this problem.
---------------------------
OK
---------------------------
If I dismiss them all the build finishes without error but none of the
prerequisite libraries or Qt plugins are in the install kit (they go
in /w the install target as expected).
I suspect a PATH problem but have no idea how to debug this further.
OK, so I have progressed a bit. This is something to do with the MS tool
dumpbin which is used to analyse binaries for prerequisites as part of
BundleUtilities::fixup_bundle.
It looks for a suitable tool and on Windows prefers dumpbin over MinGW
objdump. In my case even though I am using MinGW for builds, I have MSVC
installed too.
So for the install target dumpbin seems to work ok to analyse the
binaries. I still don't understand why the package target goes wrong as
described in the OP.
Looking at the GetPrerequisites.cmake module I see that I can force the
choice of binary analysis tool by defining the variable gp_tool. So I
define it to "objdump" before executing fixup_bundle and it seems to
work. the only problem is that it takes about 15 minutes (on i7
processor!) to complete a package generation that takes less than a
minute when dumpbin is used :(
I would really like to know why it is going wrong with dumpbin in
package generation because using objtool is too slow!
TIA
Bill.
Regards
Bill.
