Qt's g++ builds invalid executables.
-
Windows 7 64-bit
MinGW 4.8 32-bit
Qt Creator 2.8.1
I'm not using the Qt libraries in this project.Issue history: "Windows Forum: MinGW C++11 app compiles, can't run outside IDE: 0xc000007b":http://forums.windowsforum.org/index.php?showtopic=51273
Long story short, I have a project which only contains an empty main function - no includes or actual logic. It runs fine inside Qt Creator, but when I run it standalone I get a dialog:
bq. The application was unable to start correctly (Oxc000007b). Click OK to close the application.
To test, I tried running the makefile outside of Qt Creator. Lo and behold, I got an executable that worked. But when I tried to put it in Dr. Memory, I was told it's unsupported because it's 64-bit. It was 64-bit because the first g++ in my PATH was from 64-bit MinGW. I used this Batch script to eliminate that inconsistency:
@setlocal
set PATH=C:/Qt/Tools/mingw48_32/bin/;%PATH%mingw32-make -f Makefile.Debug
endlocal@
Now, when I use the script to compile, and then run the resulting executable, I get the same error dialog.What can I do about this?

These windows error codes sometimes do carry information:
this Error Code means: 0xC000007B STATUS_INVALID_IMAGE_FORMAT ("windows error code document":http://download.microsoft.com/download/9/5/E/95EF66AF-9026-4BB0-A41D-A4F81802D92C/[MS-ERREF].pdf )This could mean that a 32 bit application tries to load a 64 bit dll.
You should probably look into this issue with "dependency walker":http://www.dependencywalker.com/ or with "PEStudio":http://winitor.com/.

Somehow the link above does not work. so Here is the full link to the Microsoft Windows Error Code Document:

Copy the text an paste it to a browser! (it will download a pdf document)

Apparently it does depend on a 64-bit DLL, but I'm not yet understanding what I can do about it.
I listed the Dependency Walker results, and my reaction to them, in the linked thread. They didn't seem to lead anywhere useful, but here they are again:
@ Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.

I know my reply is a bit late... But have you been able to solve the issue?
