farzane lk posted a topic in Calling External CodeHello I have received a LabVIEW dll and the corresponding header files so that I can send a trigger to a skin stimulation device. when I use the loadlibrary command in my Matlab script, I receive these two errors: "We don't know the Compiler" and "We don't know the ProcessorType architecture" Which means while reading the "platdefines.h", the Compiler and the ProcessorType does not match the ones listed in ifs. I have set c++ compiler to visual studio 2015 in Matlab. (also tried MinGW). the system I`m using is Windows 10 (tried on 7, too), 64bit. I read somewhere that manually defining the ProcessorType and the compiler might solve the issue. But the problem is I Don`t know what they are. (when these two conditions below are not accepted.) #elif defined(_MSC_VER) || defined(_NI_VC_) #define Compiler kVisualC #elif defined(_M_X64) #define ProcessorType kX64 -------------------------------------------------- How should I find out the ProcessorType and the compiler I have? I`d be EXTREMELY THANKFUL for any solutions you can think of. P.S.1 I attached all the headers and the Matlab error.jpg P.S.2 The code seems to work fine on manufacturers system with Matlab 2011. so it may be Matlab-related, but I don`t get how since the error is from platdefines header file. extcode.h fundtypes.h hosttype.h ILVDataInterface.h ILVTypeInterface.h lv_epilog.h lv_prolog.h platdefines.h STIM.aliases STIM.dll STIM.h STIM.ini STIM.lib
Stobber posted a topic in LabVIEW GeneralI was mucking around in General Error Handler.vi today and noticed a weird subVI with a really intersting comment inside. Thought I'd share it with the crowd, since it applies to time-critical processes, thead swapping, and general compiler insights.
Did you happen to catch the announcement a while back (LV2010 era) that LabVIEW source was being compiled to DFIR (DataFlow Intermediate Representation) and then to LLVM IR (Low Level Virtual Machine) before being compiled to target-specific machine code? Let's look at LLVM a moment; it's exciting. This acronym is not just some LabVIEW R&D mumbo jumbo; the LLVM compiler is something that has cause quite a stir in the programming community for some time now. In 2012 -- two years after NI R&D publicly announced that LabVIEW was leveraging LLVM -- LLVM won the ACM Software System Award. Who else has won this yearly award given to only one project? Ever heard of, say, UNIX? Java? The World-Wide Web? Eclipse? Apache? Shite -- i guess this makes LLVM A Big Deal. A couple top-notch articles I've caught recently include: "IR is better than assembly": https://idea.popcount.org/2013-07-24-ir-is-better-than-assembly/ "Kaleidoscope and the Lexer": http://llvm.org/docs/tutorial/LangImpl1.html And my favorite, for the dear memories and sheer genius of this guy: "Statically Recompiling NES Games into Native Executables with LLVM and Go": http://andrewkelley.me/post/jamulator.html This stuff is blowing my mind, and I'm really glad to know LabVIEW has hitched its wagon to LLVM. Keep it up, Compiler Team -- chime in here and tell us more.
gregstoll posted a topic in LabVIEW GeneralHi all - I've just posted a tool to analyze compiled code complexity of VIs in a project at http://forums.ni.com...12/td-p/2121692. Note that compiled code complexity is a new feature in LabVIEW 2012, and so this won't work with earlier versions. I'd be happy to answer any questions here or on the forums!
