The library comes with instructions on how to compile it on Linux:
./autogen.sh
./configure
make
But I can't find any source on the Internet to help me compile this code directly on Windows, just as if I never had a Linux machine.
nDPI is hosted here: https://github.com/ntop/nDPI
You could set up a linux-like CLI using Cygwin (very useful tool) and cross compile to Windows. It's not a complicated process and there is a lot of documentation around the Internet. I recommend using the MinGW 32 cross compiler.
You can use NFStream which provide Windows support and use nDPI as a DPI engine.
You have to edit some lines of source code and add the files
ntop_win32.h and ntop_win32.c
Then you can compile nDPI with Visual Studio.

Disclaimer: Please read question carefully, This question has a twist so read it till end.
So JSON-C is one of the highly popular library to work on JSON using C programming. Basic illustration on current work, whatever code building here is for multi-platform. Currently Linux & Windows are supported platform and I have small issue with Windows related JSON-C part.
I'm using Cygwin for Windows development, and when I compile JSON-C code as per provided instruction on it's GitHub page, using CMAKE it works out quite good and build system is able generate DLLs for Windows. But if you have worked with Cygwin then you must know that whatever is built using Cygwin, will have dependency on it's run-time environment (cygwin1.dll) (Why does GCC-Windows depend on cygwin?) and it won't be an independent DLL that can be moved around to different system with same architecture. So with this dependency on Cygwin if my project is built on Windows platform, I have to carry around either Cygwin Run-Time Env. or I have to make sure Cygwin installed on target system for smooth execution. This sort of dependency I do not wish to have for my project, it can ruin user experience.
So what I want as help here, Is there a way to build JSON-C independent of Cygwin (run-time environment)??
NOTE: I already know that, if using Cygwin one wishes to create such an independent DLL for Windows then that can be done using few parameters to compiler and some additional macros placed in-front of function declaration as described here Creating a DLL in GCC or Cygwin?
But I don't see such support in source code JSON-C for Windows. So I was just wondering if JSON-C Dev team has kept some provision via build-system then I'm keen to know that part.
PS: I have not dipped into JSON-C build system yet due to my other development, so if anyone out there (my beloved community) has anything on this then please share, that would be terrific.
EDIT
Forgot to mention the version I'm using :p
json-c-0.13.1-20180305
I am able to build JSON-C 0.14-20200419 (from https://github.com/json-c/json-c) under MSYS2 with MinGW-w64 - both static and shared - using these instructions (replace /usr/local as needed):
INSTALLPREFIX=/usr/local
mkdir -p build_static build_shared &&
cmake.exe -Wno-dev -GNinja -DCMAKE_INSTALL_PREFIX:PATH=$INSTALLPREFIX -DCMAKE_BUILD_TYPE:STRING=Release -DBUILD_SHARED_LIBS:BOOL=OFF -DBUILD_TESTING:BOOL=OFF -S. -Bbuild_static &&
cmake.exe -Wno-dev -GNinja -DCMAKE_INSTALL_PREFIX:PATH=$INSTALLPREFIX -DCMAKE_BUILD_TYPE:STRING=Release -DBUILD_SHARED_LIBS:BOOL=ON -DBUILD_TESTING:BOOL=OFF -S. -Bbuild_shared &&
ninja -Cbuild_static install/strip &&
ninja -Cbuild_shared install/strip &&
echo Success
If you don't have ninja you can probably also use -G"MSYS Makefiles" and use make instead of ninja.
Note that MinGW-w64 is different from Cygwin in that it compiles to native Windows binaries without dependancies on a compatibility layer (like Cygwin's cygwin1.dll). The following screenshots illustrates this:
TL:DR;
Can I write GUI programs on Win 10 (64) using Rust without installing the full MinGW toolchain (nor the MS equivalent)?
Supplementary questions:
- If not, should I just go ahead and install MinGW?
- Does anything GNUish in Windows 10 Anniversary Update change any of this?
Longer version
I saw that Rust is the most loved programming language hereabouts so 15 minutes ago...
I read
No additional software installation is necessary for basic use of the GNU build.
Rust's support for the GNU ABI is more mature, and is recommended for typical uses.
So I downloaded Windows (GNU ABI †) (.msi) 64-bit to my PC running Windows 10.
TUI
I read some basic intro and used rustc to compile a Hello World! and ran it OK. I then read about cargo and reorganised buit and ran the same code using that.
GUI
I then searched for Rust GUI and found Kiss_UI
a simple UI tookit for Rust
So I did a cargo new Hello_GUI --bin and added
[dependencies.kiss-ui]
git = "https://github.com/cybergeek94/kiss-ui"
to Cargo.toml
I cut and pasted a simple example from that website into main.rs
I then ran cargo run --verbose. It did
Updating git repository `https://github.com/cybergeek94/kiss-ui`
Updating registry `https://github.com/rust-lang/crates.io-index`
Downloading iup-sys v0.0.3
Downloading libc v0.2.14
Downloading libc v0.1.12
Compiling libc v0.1.12
...
warning: crate `Hello_GUI` should have a snake case name such as `hello_gui`, #[warn(non_snake_case)] on by default
error: linking with `gcc` failed: exit code: 1
note: "gcc" "-Wl,--enable-long-section-names" ...
note: ld: cannot find -liup
error: aborting due to previous error
So I learned two things
I need to use snake case.
GUI programming is not "basic use".
I have no complaints about either of these points but could use a clue or two about the second:
Assuming I want to write a GUI equivalent of Hello World in a simple way, what are my main options now?
According to its documentation, kiss-UI depends on the IUP library.
The error from gcc (can't find -liup) suggests that you don't have IUP installed. You may be able to install it and have things work; it depends on whether the IUP bindings used by kiss-UI can cope with windows.
Some other GUI libraries can be found at awesome-rust. There are bindings to libraries like Qt and Gtk. If you know the windows API, you could also check out the winapi crate.
If you want to avoid messing with linking and stuff, you could try using a pure rust library like conrod, which should 'just work' on windows.
To answer your more broad questions:
See the footnote on the downloads page. The MSVC version of rust depends on MSVC being installed. The GNU/MinGW build is standalone.
I would like to compile the Linux-based mail client, Geary, for my Windows computer.
I'm wondering if I could compile it using a program such as MonoDevelop on my Linux machine with the target being Windows, or if I'll have to use cygwin or mingw on my Windows machine.
Thanks
You can cross compile on Linux to Windows. There is a MinGW build for Linux. Use valac -C to produce C sources then i586-mingw32msvc-gcc to compile the sources and link against Windows DLLs of the libraries needed. Vala determines includes using pkg-config which will pick up compilation arguments from the host system. You can override this by setting PKGCONFIG_PATH to the directories where your Windows libraries' .pc files live.
Alternatively to compiling, you can run Geary on Windows 10 via the WSL.
This question here lead to give it a try. It can be done, but requires many steps and it doesn’t work very well for the time being.
https://heracl.es/ephemera/2018/08/08/geary/
Do you really need to compile it? If you have windows 10, you can run a linux environment, for instance ubuntu. Then Geary runs. I can confirm, as I have it running NOW.
There are several tutorials on how to get Ubuntu running in the WSL on Win10.
I want to use the Gnome GLib in a Windows environment using the free MinGW compiler to develop in C. The problem is, I have absolutely no idea how to compile this library. Would any of you please explain what tools are needed to accomplish this and what instructions need to be followed?
GLib is available pre-compiled for Windows and has been for ages: http://www.gtk.org/download/windows.php.
You need to use MSys, it is downloadable from MinGW site. Using MSys you will be able to build GLib: http://www.mingw.org/wiki/Bootstrapping_GLIB_with_MinGW
I'm having some trouble installing and configuring qt on my vista laptop.
I'm trying to setup a development environment on my laptop where I compile from the command line, because that's how the environment is setup on my university's linux machines, so I don't want to tie myself to some IDE .. (plus, real programmers use the command line!)
I haven't used the command line before for C++ development, it was all MSVC, so now I'm having a bit of trouble.
I'm still using MSVC, but from the command line. I practically have no idea what's going on, I just know that I have to run:
qmake
nmake
to compile my code!
I downloaded the opensource version of qt, and did the configuration, and tried a simple qt application (from a tutorial) and it worked, it compiled and executed pretty much as expected.
Now, when I decided to run another project that uses opengl, I got the following error:
fatal error C1083: Cannot open include file: 'qgl.h': No such file
or directory
I'm not sure where does the compiler look for header files, and I didn't copy any header files anywhere, I assume that configure.exe worked its magic somehow and added the include directory to one or more enviroment variables or to some registery location or whatever other peculier places that the MSVC compiler searches for to find include directories.
However, what I did was search my C:\qt\include\ folder to make sure that qgl.h exists, and sure enough there it was. so why can't nmake find it?
I think the actual solution to this is in your pro file:
QT += opengl
If you want to stay with the command line anyway (plus use it on a linux box later / parallel) I'd suggest at least trying out the MinGW version of Qt. I'm using it regularly, and besides of the non-existance of a GUI it works pretty well. Using MinGW also has the advantage that you can simply download and install the MinGW edition of Qt and don't need to reconfigure or recompile anything.
Also, trying out QtCreator might be interesting. It's still beta and requires the beta Qt 4.5 but it's a nice small IDE that integrates nicely with gcc.
Two potential solutions (they solved issues at my workplace)
Do you have qt include and bin folders in the PATH variable? I think the doc says only one of these is needed, but one of the students had Vista and putting the other in the PATH variable solved a "Cannot open include file" problem.
If you're using MSVC did you run configure and nmake from the Visual Studio command prompt? We had problems when using the bare windows Command Prompt because the VS one adds a lot of temporary environment variables to the configure process.
Good luck
Install the complete Qt SDK for Windows which includes Qt 4.6 SDK, Qt Creator 1.3, and MinGW.
It will also install "Qt Command Prompt" launcher that you can use to build Qt apps from the command line.
I'm sure you're more familiar with MSVC than MinGW, as I do too (I've been using MSVC 6.0 to MSVC# 2008 for developing .NET apps).
But try MinGW with Qt and I think it's better for long term. I do some C++ development on Linux too so getting familiar with MinGW will be beneficial for you in cross-platform C++/Qt development.
For more info, see Installation of Qt 4.6 SDK for Windows.
Qmake generates Makefile from *.pro file located in current directory. It has qt path compiled in. Type "qmake -v" to see it. You can't move qt's dir after compiling it. If You haven't moved it, first maybe try to install Qt following instruction from INSTALL file. Good luck.
The opensource version of Qt does not provide profiles (mkspecs in qt terms) so qmake can generate nmake (msvc) compatible makefiles.
You have to use mingw/gcc.
