How can I compile a swift file on Mac as an executable to run on Windows?
All I need is an executable that can be called from C# code.
If you have a proper swift library module for Windows, your swift compiler for macOS can generate object files for Windows, such as Hello.obj.
Moreover, you can build the executable (ex. Hello.exe) if you have the special linker and some C/C++ runtime object files for Windows.
All you need one is follows.
Copy the directories to the macOS from the package for Windows.
1) Install Swift for Windows ver-1.5 (https://swiftforwindows.codeplex.com) on Windows
2) Copy directories to macOS from Windows
SwiftForWindows/Swift/lib/swift // Swift library for Windows (MinGW)
SwiftForWindows/Swift/lib/mingw // C/C++ runtime object files (MinGW)
Install Swift compiler for MacOS (https://swift.org/builds/swift-3.0-release/xcode/swift-3.0-RELEASE/swift-3.0-RELEASE-osx.pkg)
You should use the same version for the library module and compiler. Use the version 3.0. Swift 3.0.1 or 3.1 will not work with SwiftForWindows-1.5.
Install MinGW linker with Mac Port
1) Install Mac Port (https:// www.macports.org/install.php)
2) $ sudo port install x86_64-w64-mingw32-binutils
3) Create directory bfd_ld and copy /opt/local/bin/x86_64-w64-mingw32-ld and name to ld
$ mkdir bfd_ld
$ cp -p /opt/local/bin/x86_64-w64-mingw32-ld bfd_ld/ld
More Settings
1) Rename the directory in macOS
mv SwiftForWindows/Swift/lib/swift/mingw SwiftForWindows/Swift/lib/swift/windows
2) Copy C runtime objects (3 files)
cp SwiftForWindows/Swift/lib/mingw/*.o bfd_ld
Compiling
echo "print(Hello)" > Hello.swift
~/Library/Developer/Toolchains/swift-3.0-RELEASE.xctoolchain/usr/bin/swiftc -target x86_64-pc-windows-gnu -resource-dir SwiftForWindows/Swift/lib/swift -tools-directory bfd_ld -L SwiftForWindows/Swift/lib/mingw -lswiftSwiftOnoneSupport -o Hello.exe Hello.swift
This will generate Hello.exe. You can ignore the 'Warning: .drectve' message.
Running
The executable file will need the DLL's in the directory 'SwiftForWindows/My Programs'.
Copy Hello.exe to the directory in Windows and run it.
Good luck to you. Thanks.
If you want to run Swift code on Windows, the closest you can get is swift-windows. I have never used it but it looks like you can compile Swift 3.0 code to a Windows executable.
To download pre-built binaries, try this link. It requires Windows 10 64 bit and the Visual Studio 2015 SDK. Additionally you will have to have a cygwin or mingw environment.

There are some posts about this for the older releases of MATLAB, but they don't seem to work for R2016a.
I'm trying to install MatConvNet on Ubuntu 16.04. When I run the vl_compilenn command as described here, it gives me a warning as follows:
Building with 'gcc'.
Warning: You are using gcc version '5.4.1'. The version of gcc is not supported.
The version currently supported with MEX is '4.7.x'. For a list of currently supported
compilers see: http://www.mathworks.com/support/compilers/current_release.
I have already installed gcc-4.7 and g++-4.7 using apt-get install gcc-4.7 g++-4.7. How can I force MATLAB to use these versions and not the default ones?
Few hints, not a complete tutorial how to do it.
Probably the simplest would be to edit the MATLAB's Mex XML configuration file:
mex -setup C
cc = mex.getCompilerConfigurations('C', 'Selected')
edit(cc.MexOpt)
The mex setup usually creates a copy in your home folder (~/.matlab/<version>/mex_C_glnca64.xml), so you should be able to edit it without root.
There you probably need to change the section:
<GCC>
<cmdReturns name="which gcc" />
</GCC>
which I guess searches for the location of the gcc command to your gcc version and assigns it to the $GCC variable. Plus you can change the version name in the header.
Additionally you need to do the same for the C++ language.
This works with R2016b:
Install the required GCC version with apt install (gcc-4.9 and g++-4.9 in my case).
Create a bin folder in your home, i.e. ~/bin.
Create the following links with ln:
ln -s /usr/bin/gcc-4.9 ~/bin/gcc
ln -s /usr/bin/g++-4.9 ~/bin/g++
If using CUDA, create a file called nvcc in the ~/bin folder, with the following contents (don't forget to make it executable: chmod +x ~/bin/nvcc):
Contents:
#!/bin/sh
exec /usr/lib/nvidia-cuda-toolkit/bin/nvcc -ccbin gcc-4.9 "$#"
If necessary replace /usr/lib/nvidia-cuda-toolkit/bin/nvcc with the correct location of the nvcc binary.
Open MATLAB and follow the instructions for compiling MatConvNet.
This may be a copy of this question How can I use the PoDoFo library for annotating PDFs on iOS? not responded yet.
i know how to use/create static libraries into xcode projects for iOS. i was looking for a free PDF library which support in memory editing of pdf documents and i came to know that PoDoFo done it very well, i tried to build this library for xcode but i really don't know how to play with CMake. can any body tell me how can i use this library into my iOS application.
thanks
This is an extract from Podofo 'Read me' file
CMake builds on Mac OS X
Mac OS X users can build PoDoFo using CMake either by generating conventional UNIX Makefiles (the "Unix Makefiles" CMake target) or generating an XCode project (the "Xcode" target). In either case the following applies.
You will need freetype and fontconfig. It's possible to omit the use of libjpeg (see the platform-independent documentation) but by default libjpeg will also be required. If you have these libraries already (say, from fink or DarwinPorts) you can skip the following section and update the CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH arguments appropriately.
Dependencies
I'll assume you're installing podofo and any required libraries into $HOME/libs . Adjust to taste, but keep it consistent.
The easiest way to get any required libraries is to use MacPorts to install the libjpeg, fontconfig, and freetype libraries. Once you've installed MacPorts, just run:
/opt/local/bin/port install fontconfig freetype jpeg tiff lua
MacPorts will automatically build the libraries and their dependencies, installing them in /opt/local.
If you want to distribute the libraries with your application, all you'll need to do is use install_name_tool to set appropriate relative paths for their linkage and include them in your application bundle - just like you do with any other libraries.
PoDoFo itself
You should be able to configure and install podofo on Mac OS X using:
cmake -G "Unix Makefiles" \
-DWANT_FONTCONFIG:BOOL=TRUE \
-DCMAKE_INSTALL_PREFIX=/opt/podofo \
-DCMAKE_INCLUDE_PATH=/opt/local/include \
-DCMAKE_LIBRARY_PATH=/opt/local/lib \
../podofo
make
sudo mkdir /opt/podofo
sudo chown $USER /opt/podofo
make install
change "Unix Makefiles" to "Xcode" if you want to build an XCode project instead, then instead of running make' andmake install' just open the project file and work as normal
Instead of using 'XCode' in the command, type 'Xcode', (c lowercase) and it should do the trick.
I've had Eclipse for Java on my computer for a few years, and decided to install the CDT and learn C. I installed both MinGW and Cygwin and the CDT detects and tries to use them when I make a new project.
I choose File > New C++ Project and choose Hello World C++ Project and the CygwinGCC toolchain. I name the project "asdf" and hit "Build Debug" in the toolbar. The compiler completes without error. I hit Run and nothing happens.
Browsing to the project directory manually and running asdf.exe gives me an error saying:
"The program can't start because cygwin1.dll is missing from your computer. Try reinstalling the program to fix this problem."
The same thing happens using MinGW, only a different dll is missing.
What do I need to do to have a usable .exe?
(I'm running Windows 7 x64 and the newest version of Eclipse and the CDT.)
EDIT:
The compiler output is as follows:
**** Build of configuration Debug for project asdf ****
make all

This error message means that Windows isn't able to find "cygwin1.dll". The Programs that the Cygwin gcc create depend on this DLL. The file is part of cygwin , so most likely it's located in C:\cygwin\bin. To fix the problem all you have to do is add C:\cygwin\bin (or the location where cygwin1.dll can be found) to your system path. Alternatively you can copy cygwin1.dll into your Windows directory.
There is a nice tool called DependencyWalker that you can download from http://www.dependencywalker.com . You can use it to check dependencies of executables, so if you inspect your generated program it tells you which dependencies are missing and which are resolved.
You can compile with either Cygwin's g++ or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll (and others) PATH to the system Windows PATH, before any cygwin style paths.
Thus add: ;C:\cygwin64\bin to the end of your Windows system PATH variable.
Also, to compile for use in CMD or PowerShell, you may need to use:
x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe
(This invokes the cross-compiler, if installed.)
To add to this and save someone another google, just do this in cmd:
set PATH=%PATH%;C:\cygwin64\bin
I've searched a lot, but didn't find the solution.
I need to package my ios app into .deb.
I have installed Mac Ports and dpkg, I have control file in DEBIAN folder in MyApp folder
I run /opt/local/bin/dpkg-deb -b MyApp and get error.
dpkg-deb: ignoring 3 warnings about the control file(s)
Can't use format gnu: No such format 'gnu': Invalid argument
There is another topic: How to create .deb packages on Mac OS X, but no answer to this question.
I assume you are using a tar implementation that does not support the GNU tar fotrmat, which dpkg-deb expects for its usage.
You should install GNU tar and either recompile dpkg to use that (usually named gtar) instead of simply the executable tar, or prepare a PATH environment to prefer the GNU tar when using dpkg-deb.
Newer dpkg versions detect this requirement at build time and will abort the build, to make sure this does not happen.
I am following This Tutorial on installing MGTwitterEngine on my MAC osx 10.6.2.
I am stuck on this step:

Thus, I cannot use TERMINAL to install YAJL to get my app to build. Help needed.
P.S.
In terminal preferences, Shells Open With is either /usr/bin/login or /bin/bash
YAJL is supposedly installed at /Users/Rex
I am using OSX 10.6.2
Solution was that my OS is snow leopard and the version of Xcode i was using was not. Re-installing the proper xcode update solved it.
