How to cross-compile DLL with exported functions
I’m working through a DLL hijacking exercise, and have a DLL written which works as expected when compiled in Visual Studio. Essentially, when the DLL is loaded, it executes a shell command and passes off legitimate functionality (in this example, the CheckEvenOdd and PrintAMessage functions) to the ori…
Avoiding header collisions when cross compiling
I have a linux project I want to port to windows. Under Linux I did set up my makefile to run x86_64-w64-mingw32-g++ when I do call make ARCH=win The problem is that some headers I need (tcl.h and friends) are located under ‘/usr/include’ and if I pass that directory with the -I flag I will get a …
QThreads using MinGw doesn’t work properly under windows
I’m developing a large optimzation tool using Qt. For a better CPU usage I use QThreads. Then I move worker objects (derived from QObject, containing non QObject data members) into the threads. Everything looks fine, builds fine and runs smoothly on Linux using GCC and Qt 4.8 However using MinGw using Q…

For this I downloaded SDL2-devel-2.0.4-mingw.tar.gz from here prog.cpp: Makefile: Now making gives the error: Why undefined reference to `SDL_main’ ? Although I specified -lSDL2main ? What …
MinGW DLL project compatability with linux
I’ve recently created a DLL project using the MinGW (4.8.1) compiler through the CodeBlocks IDE, and in the debugging output folder I have: my “.dll” (“AttribRdr.dll” in this case) file with an Export Definition File and finally a “.a” file (“libAttribRdr.a̶…

Strange Output Difference Between GCC and MinGW (C++)
I’m working on a project for a computer science class. I wrote the code and tested it using MinGW, and it works fine. I then copied the code over to the university’s Linux server and tested it there, since that’s what my professor grades assignments on. The output is very different – l…
