[solved] Questions on deployment
-
You could start with "Mission Accomplished" ;-)
msvcrt.dll is the microsoft C runtime library. It is used by MinGW too, as MinGW uses native Windows API. Kernel32.dll is ... the kernel :-) ... it's loaded by all applications, you must not copy that into the app directory.
What DLLs do you have in your application directory now?
For test purposes: I usually have a vanilla windows installation running in a virtual machine. You can install your stuff and roll back to a pristine snapshot once you're done.

- libgcc_s_dw2-1.dll
- libgomp-1.dll
- libpthread.a
- libstdc++6.dll
- mingwm10.dll
You suppose I should probably take msvcrt.dll, too?
-
This looks good. You do not need msvcrt.dll.

I'd originally marked this solved, but...I realized my job isn't quite finished here. Now that I've discovered all the files necessary to include in my distribution, is there a way to use the Deployment methods in the Run Settings to automatically copy the necessary files, and the executable, into a "delivery" directory that I can then zip and send to a customer?
-
Hm, maybe that's better asked as a new topic in the Tools forum.
-
Good enough...I'll ask over there. Thanks.
-
Well...here I thought I had this thing solved. Just tried it on a second application (copying over the same files) and...it doesn't run.
I've looked at the DW log, and it doesn't indicate any missing modules. The program runs OK within Creator. What else besides a missing library might cause the program not to run?
-
That's hard to say without knowing the actual setup. Do you get any error messages from windows?
-
Nope. If I double-click on the program from the GUI, it sits for a moment, but does nothing. If I try in invoke from the CLI, I get a prompt back immediately.
I think I found an issue: I copied my DLLs over from the directory with the program that worked, but according to DW, the two programs expect different libraries. One is from \windows\system32; the other from \windows\syswow64. I'm trying to look into that, but at the moment, Creator is giving me some grief that might be related to my downloading the newest release.
Guess I should nuke the build directories and start over?
-
Oh - looks like you mixed up 32bit and 64bit libraries and executables. This will lead to disaster - as you've noticed already :)
-
I don't know how I did that, though. According to DW, the two programs are using different libraries, but...I don't see any differences in my build settings.
I could go get the 64-bit libraries for the second program, but I'd rather fix my builds so they use the same ones.
-
I deleted and regenerated the build directories...same behavior.
I think my comment about \windows\system32 vs. \windows\syswow64 may have been a red herring. When I worked in DW and watched a bit more carefully, I noticed that BOTH programs begin with system32 in the dependency tree, but when I profile, BOTH change to syswow64. (This is odd, but I'm not sure it's related to my issue.) When I refresh, both revert to system32.
Both programs show identical dependencies.
Both programs have the mingw files MINGWM10.DLL and LIBGCC_S_DW1-2.DLL in their run directories.
But, one program runs, and the other doesn't. I'm kind of at a loss to explain this.
EDIT:
Another data point: I added the files:
- libgomp-1.dll
- libpthread.a
- libstdc++-6.dll
to the directory of the malfunctioning program (even though they weren't necessary for the one that works)...same results.

If anyone's willing to take a look, here's the DW log file after a profile:

I can't read these tea leaves, but perhaps someone else can.
