Hi, I would like to ask for some help regarding C Compilers in Mathematica. The problem I have is that Mathematica does not recognize the presence of a C Compiler. When I do CCompilers[Full] it returns: {{Name->Intel Compiler,Compiler->CCompilerDriver`IntelCompiler`IntelCompiler,CompilerInstallation->None,CompilerName->Automatic},{Name->Generic C Compiler,Compiler->GenericCCompiler,CompilerInstallation->None,CompilerName->Automatic}} And when I do CCompilers[ ] it returns { } Also, DefaultCCompiler[] NVCCCompiler I have Windows 7 Ultimate 64 bits. I followed this thread: http://mathematica.stackexchange.com/questions/5487/how-do-i-get-mathematica-to-recognize-a-c-compiler-on-a-64-bit-windows-machine and installed two C Compilers: one via .NETFramework and Windows SDK 7.1, the other one was the 64 bit MinGW. Unfortunetely Mathematica 8 still does not recognize any C Compiler. I tried $CCompiler = {"Compiler" -> GenericCCompiler, "CompilerInstallation" -> "C:â?¦â?¦Path", "CompilerName" -> "x86_64-w64-mingw32-gcc.exe"}; After this i tried CCompiler[ ] and the output was: {"Compiler" -> GenericCCompiler, "CompilerInstallation" -> "C:â?¦â?¦Path", "CompilerName" -> "x86_64-w64-mingw32-gcc.exe"} Nevertheless, when I do CCompiler [ ] the result shows nothing again. Regarding the Microsoft CCompiler, Iâ??m not sure what executable file is appropriate, I read somewhere that it should be cl.exe but I canâ??t find this file anywhere. As you can see I am not very familiar with this subject. Could you let me know what I am doing wrong here? I really need to speed up some code. Thanks in advance Joao
