Including Generated C Code in External Applications (C Generator)

If you have an existing makefile or project you created in another IDE in which you want to include the generated C code, you can use that makefile or project instead of the makefiles generated by the LabVIEW C Generator. You can include the generated C code in an external project in one of the following ways:

• Add the necessary files directly into the external project.
• Build the generated C code files into a static library, or archive file, and link the static library into the external project.
• Build the generated C code files into a DLL and load the DLL from the external project at run time.

Regardless of which method you choose to include the generated C code in the external project, you must compile the following files:

• All generated C files.
• Run-time library files from the labview\CCodeGen\libsrc\blockdiagram directory, which include the following files:
  • CCGArrSupport.c
  • CCGArrSupport2.c
  • CCGArrSupport3.c
  • CCGClusterSupport.c
  • CCGCmplxSupport.c
  • CCGDVRSupport.c
  • CCGEnumSupport.c
  • CCGFltSupport.c
  • CCGFXPSupport.c
  • CCGIntSupport.c
  • CCGStrSupport.c
  • CCGTimeSupport.c
  • CCGTokString.c
  • CCGUDClassSupport.c
  • CCGVariant.c
  • CCGXMLSupport.c
  • ExecStack.c
  • LVBlockDiagram.c
  • LVCGenRTInit.c
  • LVContext.c
  • LVHeap.c
  • LVTdp.c
  • MemCheck.c
  • nbemptybin.c
  • nbfifo.c
  • nbfifo_inst.c
  • nbitemtable.c
  • NumText.c
  • rtmath.c
  • ViLib.c
• The following files from the labview\CCodeGen\libsrc\comms:
  • CCGVIRefSupport.c
  • crc.c
• The following files from the labview\CCodeGen\libsrc\frontpanel:
  • LVArrayControl.c
  • LVBoolean.c
  • LVClusterControl.c
  • LVEnumCtl.c
  • LVFrontPanel.c
  • LVListbox.c
  • LVNumeric.c
  • LVRadioClustCtl.c
  • LVRing.c
  • LVScrollbar.c
  • LVString.c
  • LVTab.c
  • LVTable.c
  • LVTimestamp.c
  • LVTree.c
  • Pict.c
• Headless.c from the labview\CCodeGen\libsrc\os\common directory
• arrresize.c from the labview\CCodeGen\libsrc\analysis directory

You also must set the compiler options to include the following build specification output path directories in the header search paths:

• The directory in which you saved the generated C files. You specify this directory in the Destination directory option on the Information page of the C Code Generation Properties dialog box.
• labview\CCodeGen\include\blockdiagram
• labview\CCodeGen\include\comms
• labview\CCodeGen\include\frontpanel
• labview\CCodeGen\include\platform\subdirectory, where subdirectory is the platform you are using
• labview\CCodeGen\analysis\development\include
• labview\CCodeGen\analysis\LV\source\include

You also must build and link to the analysis library if you use the Mathematics or Signal Processing VIs in the exported VI.

Tip  You also can generate C code from the command line.
