mac os x - How to use MacPorts' gcc with CreateLibrary?

Short version: What's the simplest way to use MacPorts' gcc with CreateLibrary?

Long version:

CreateLibrary uses /usr/bin/gcc by default on OS X. I can get it to use clang by using the option "CompilerName" -> "clang++" or "CompilerName" -> "c++" (I'm using C++).

However, I would like to use MacPorts' gcc because it boosts the performance significantly for this particular program I need to compile. It also supports OpenMP; the system compiler doesn't. "CompilerName" -> "g++-mp-5" tells me that

CreateLibrary::instl: The compiler installation directive "CompilerInstallation" -> "/usr/bin" does not indicate a usable installation of "GCC"

So I tried "CompilerInstallation" -> "/opt/local/bin", which is the location of g++-mp-5. This results in the same error:

CreateLibrary::instl: The compiler installation directive "CompilerInstallation" -> "/opt/local/bin" does not indicate a usable installation of "GCC"

Is there a simpler solution than using GenericCCompiler?

Answer

I ended up using the GenericCCompiler driver, as follows:

$CCompiler = {
 "Compiler" -> CCompilerDriver`GenericCCompiler`GenericCCompiler, 
 "CompilerInstallation" -> "/opt/local/bin", 
 "CompilerName" -> "g++-mp-5", 
 "SystemCompileOptions" -> "-O2 -m64 -fPIC -framework Foundation -framework mathlink"
};

The compiler definition should use "SystemCompileOptions" instead of "CompileOptions" so that the user can set their own custom "CompileOptions" when desired.

CreateLibrary[{"mylib.cpp"}, "mylib", 
 "IncludeDirectories" -> "/opt/local/include", 
 "ShellOutputFunction" -> Print, "ShellCommandFunction" -> Print, 
 "Language" -> "C++"]

It is good to note that the "Libraries" and "SystemLibraries" options are not usable on OS X because this driver auto-appends .lib to any library name, which is incorrect on OS X.

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...

dynamic - How can I make a clickable ArrayPlot that returns input?

I would like to create a dynamic ArrayPlot so that the rectangles, when clicked, provide the input. Can I use ArrayPlot for this? Or is there something else I should have to use? Answer ArrayPlot is much more than just a simple array like Grid : it represents a ranged 2D dataset, and its visualization can be finetuned by options like DataReversed and DataRange . These features make it quite complicated to reproduce the same layout and order with Grid . Here I offer AnnotatedArrayPlot which comes in handy when your dataset is more than just a flat 2D array. The dynamic interface allows highlighting individual cells and possibly interacting with them. AnnotatedArrayPlot works the same way as ArrayPlot and accepts the same options plus Enabled , HighlightCoordinates , HighlightStyle and HighlightElementFunction . data = {{Missing["HasSomeMoreData"], GrayLevel[ 1], {RGBColor[0, 1, 1], RGBColor[0, 0, 1], GrayLevel[1]}, RGBColor[0, 1, 0]}, {GrayLevel[0], GrayLevel...
