From a technical POV, what is it that MinGW does that makes gcc possible on windows?

I believe the header provides given by Microsoft (e.g. windows.h and winusb.h) are certainly not in fact ideal with GCC. The MinGW project includes header data that team up with GCC so you can easily phone Microsoft window functions like ReadFile coming from your program. The last opportunity I evaluated, MinGW only had some of the Microsoft header files; it was actually missing out on winusb.h.

Why perform you intend to associate with a Windows runtime public library? I comprehend that cross-compiler interop is achievable because of the truth that I as quickly as created a DLL with the Microsoft C compiler as well as contacted it coming from a MinGW (Qt) program.

Is it right to comprehend that MinGW is basically taking the gcc resource and also assembling it right into an exe for windows, i.e gcc.exe?

Doesn’t a Microsoft window installment by default currently use the Win32 API headers that subjects the Win32 API, which would certainly make MinGW delivering it once more unnecessary? Are actually the headers MinGW offers different to the ones that include a Windows setup?

When I have a product data put together by MinGW gcc, can I merely attach it to the C runtime library on windows? Because of the simple fact that things file created through MinGW gcc could not be actually suitable( like makes use of the quite same contacting conventions) as the C runtime library on home windows, I would certainly strongly believe not.

GCC is actually a multi-platform compiler so there is a Linux model, a MacOS variant, a Windows model of this particular compiler. The “MinGW GCC” is actually amongst a minimum required of 2 Windows variations existing. The “MinGW body” is actually just a selection of the Windows variations of some GNU devices.

What perform you indicate by “gcc resource”? When you point out “gcc source” you might indicate “the resource code of the GCC compiler”. MinGW is actually a home windows variant of GCC, so it takes any C source code as well as makes executables, as well as it is GCC so it possesses the features of that compiler.

I simply inspected out the MinGW Wiki access and also the “given due to the Win32 API” seems to make clear the distinction in between “Cygwin” and “MinGW” – certainly not between “MinGW” and also the Microsoft C compiler:

MinGW typically connects to “msvcrt.dll” which features Microsoft window. This documents features conventional C functionalities like “printf()”.
Microsoft Visual C++ in some instances links to “msvcrt.dll”, in some cases to some DLLs like “msvcr100.dll”. “msvcr100.dll” similarly features basic C functionalities nevertheless a few of them have actually enhanced performance (e.g. Unicode …). “msvcr100.dll” requires to become post-installed given that it performs certainly not featured Windows.
Cygwin hook up to data like “cygwin1.dll” consisting of the Cygwin version of the basic C features (that vary in report title managing). Needless to condition that this file carries out not included Windows however needs to be post-installed.

Taking advantage of the “Cygwin” compiler both the “gcc” order line and also the order lines of the courses established (much more exact: connected) through it need Unix-like data labels.

Unlike Linux Windows does NOT featured any type of header submits nonetheless they feature the Win32 API that has in fact to become downloaded and install (> 1GiB) coming from Microsoft. MinGW and Cygwin supply some own header data that are actually virtually suited with the Microsoft ones so it is not needed to download the Win32 API.

Unlike “libc” in Linux all these DLLs carry out certainly not straight phone call the os however they call “kernel32.dll” which features lower-level features (like “WriteFile()”) that are going to phone the operating systems.

For great deals of GNU resources there are actually two numerous variations accessible for Windows: “Cygwin” as well as “MinGW”.

About the opinion to the various other feedback:.

Most of advancement devices in Microsoft window make use of the very same thing and repaired library documents layout. (The “Watcom” compiler is among both of exemptions.) This suggests you can easily mix object and stationary public library reports organized with different compilers. (The format of.lib/. a stump public libraries made use of for compelling connecting against DLLs varies in between gcc and Microsoft so you may not mix them!).

” Cygwin” utilizes an one-of-a-kind emulation atmosphere to replicate a Unix-like file system. An unique library will definitely be connected to the systems where functionalities like “fopen” are going to convert data labels in the kind “/ home/mydir/myfile. txt” to file labels like “c: \ systems \ cygwin \ property \ mydir \ myfile.txt”.

The “MinGW” tools regardless perform like various other Windows courses and also utilize the normal Windows collections where functions like “fopen” expect “typical” Windows-like file labels like “c: \ somedir \ somefile”. Courses created due to the “MinGW” GCC compiler simulate plans created due to the Microsoft compiler.
