Re: [Tutor] Executing a C Program from RH Linux in Python for Win

[Wayne Watson]

Title: Signature.html

"I think it this case it requires executing the program command line with parameters then executing it." That is, I likely will allow the user to enter the 12 or so parameters on the command line, and execute the program as though I had entered it at a Linux prompt. The program, Wolf, uses graphics only to produce a image like a jpg file. % ./wolf -h usage: wolf [-d|m|w|c|l|i|t|u|xN|yN|rN|bN|fFILENAME|h|qN|sN|g|e|v|pN] [julian_date] [observatory] input_image output_image type "wolf -h" for help -d: detect "unexpected" object but only draw star labels. -m: draw stars labels. -w: draw label on the target image without changing its content. -i: use inverted images (white sky and black stars). -c: draw constellations lines. -t: generate photometry files. -v: draw visibility levels. -l: draw RA and DEC lines. -h: show these lines. -xN: set the center of the input image N pixels left (use negative N for moving right). -yN: set the center of the input image N pixels down (use negative N for moving up). -rN: draw the labels N pixels right of its position. -bN: draw the label N pixels below its position. -fFILENAME: draw objects from an extrenal file FILENAME. -qN: set quality of the output image (0-100) -sN: set size of the output image (0-100) -g: Create a background fits image -e: Create a image of emissivity map -u: create photometry files for stars -pN: unwrap the fisheye image. N - scale of the output image (1=normal size) >From wolf.h #define wolf #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include "cgi-draw.h"   <<-------- #include "novas.h" #include "global.h" #include "calstars.h" #include "imatrix.h" #include "cnstl.h" Alan Gauld wrote: "Wayne Watson" <sierra_mtnv...@sbcglobal.net> wrote If you can execute a C program compiled on a Linux with SWIG, then that's what I'm looking for. Nope, you need the suprocess module not SWIG. What SWIG does (fairly easily!) is allow you to build a wrapper around your C program that python can import and call the C functions like normal Python code. I don;t think you want that, you just want to run the program. What you haven't made clear yet is whether you need to get your program to interact with the C program or whether you just want to run the executable with no interaction. (This is much easier obviously!) See my OS topic for various solutions to this. -- Wayne Watson (Watson Adventures, Prop., Nevada City, CA) (121.01 Deg. W, 39.26 Deg.
