Hello :) i have two problems: 1.: i know nothing about c compilers ;-) 2.: i need to process a simple calculation several million times. therefore i compiled my function, but it would be even faster, if it was compiled inc code, wouldnt it? The Problem: When i use the compile function with compilation target->"C", i get the message no compiler found. so i downloaded the MinGW-x64 compiler as described in the help files here under "generic c compiler": http://reference.wolfram.com/mathematica/CCompilerDriver/tutorial/SpecificCompilers.html extraction is done, and i have set the path variable to the /bin folder of the compiler (windows 7). as described in the instructions, i loaded the necessary drivers via Need[..]. now CreateExecutable[...] works perfectly fine and gives me a file i can run. to solve my problem with "compilation target-> "c"" i now need to set the MinGW-x64 compiler as default. (by the way, CCompilers[] returns {} and ..[Full] returns an intel compiler i have never seen nor installed). so i continue with $CCompiler=... and set the correct installation location to the MinGW folder, as it is done in the example. The problem now is, that i still get the "no compiler found" error, referring to the help file listed above. CCompilers[] still returns {}... EclipseC++ and devC++ work perfectly fine, by the way. i have the feeling that im making a basic mistake, but i dont know which. thanks in advance, Max
