ra30cdd5 r92da231 1 """1 r""" 2 2 C types wrapper for sasview models. 3 3 … … 5 5 you wish to allow single precision floating point evaluation for the compiled 6 6 models, otherwise it defaults to *False*. 7 8 The compiler command line is stored in the attribute *COMPILE*, with string 9 substitutions for %(source)s and %(output)s indicating what to compile and 10 where to store it. The actual command is system dependent. 11 12 On windows systems, you have a choice of compilers. *MinGW* is the GNU 13 compiler toolchain, available in packages such as anaconda and PythonXY, 14 or available stand alone. This toolchain has had difficulties on some 15 systems, and may or may not work for you. In order to build DLLs, *gcc* 16 must be on your path. If the environment variable *SAS_OPENMP* is given 17 then -fopenmp is added to the compiler flags. This requires a version 18 of MinGW compiled with OpenMP support. 19 20 An alternative toolchain uses the Microsoft Visual C++ compiler, available 21 free from microsoft: 22 23 `http://www.microsoft.com/en-us/download/details.aspx?id=44266`_ 24 25 Again, this requires that the compiler is available on your path. This is 26 done by running vcvarsall.bat in a windows terminal. Install locations are 27 system dependent, such as: 28 29 C:\Program Files (x86)\Common Files\Microsoft\Visual C++ for Python\9.0\vcvarsall.bat 30 31 or maybe 32 33 C:\Users\yourname\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\vcvarsall.bat 34 35 And again, the environment variable *SAS_OPENMP* controls whether OpenMP is 36 used to compile the C code. This requires the Microsoft vcomp90.dll library, 37 which doesn't seem to be included with the compiler, nor does there appear 38 to be a public download location. There may be one on your machine already 39 in a location such as: 40 41 C:\Windows\winsxs\x86_microsoft.vc90.openmp*\vcomp90.dll 42 43 If you copy this onto your path, such as the python directory or the install 44 directory for this application, then OpenMP should be supported. 7 45 """ 8 46
