Alignment of variables in memory (a short history). In the past computers had an 8 bits databus. This means, that each clock cycle 8 bits of information could be processed. Which was fine then. Then came 16 bit computers. Due to downward compatibility and other issues, the 8 bit byte was kept and the 16 … Read more
MinGW is a GCC-port for Windows. Not all of the Windows API is supported (but for many programs the supported stuff is sufficient) and it´s only for 32bit-Programs (which often can run on 64bit-Windows too, but some can´t, and you can´t compile them as 64bit). MinGW-w64 is a improved version which supports both 32bit and … Read more
In your example, wc is a local variable which will be deallocated when the function call ends. This puts you into undefined behavior territory. The simple fix is this: const wchar_t *GetWC(const char *c) { const size_t cSize = strlen(c)+1; wchar_t* wc = new wchar_t[cSize]; mbstowcs (wc, c, cSize); return wc; } Note that the … Read more
Regarding building a DLL using MinGW, here are some very brief instructions. First, you need to mark your functions for export, so they can be used by callers of the DLL. To do this, modify them so they look like (for example) __declspec( dllexport ) int add2(int num){ return num + 2; } then, assuming … Read more
If you are using MingW to compile C++ code on Windows, you may like to add the options -static-libgcc and -static-libstdc++ to link the C and C++ standard libraries statically and thus remove the need to carry around any separate copies of those. Version management of libraries is a pain in Windows, so I’ve found … Read more
Go to ezwinports, https://sourceforge.net/projects/ezwinports/files/ Download make-4.2.1-without-guile-w32-bin.zip (get the version without guile) Extract zip Copy the contents to C:\ProgramFiles\Git\mingw64\ merging the folders, but do NOT overwrite/replace any exisiting files.
install MinGW with C++ Compiler option checked add C:\MinGW\bin to your PATH in PYTHONPATH\Lib\distutils, create a file distutils.cfg and add these lines: [build] compiler=mingw32
Excerpt from http://www.mingw.org/wiki/FAQ: What’s the difference between make and mingw32-make? The “native” (i.e.: MSVCRT dependent) port of make is lacking in some functionality and has modified functionality due to the lack of POSIX on Win32. There also exists a version of make in the MSYS distribution that is dependent on the MSYS runtime. This port … Read more
Your commands are wrong ! Go to the directory where your main.cpp file is, and try the following. g++.exe -Wall -c -g main.cpp -o obj\Debug\main.o g++.exe -static -static-libgcc -static-libstdc++ -o “bin\Debug\Hello World.exe” obj\Debug\main.o then you’ll no longer need to copy the DLLs (for your Hello World program). Other notes: The MinGW installation instructions recommends setting … Read more
The default generator for Windows seems to be set to NMAKE. Try to use: cmake -G “MinGW Makefiles” Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don’t forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again … Read more
