                      2: =================================
                      3:
                      4: Here is a description of the steps necessary to compile PARI with the MSVC
                      5: compiler under WIN32.
                      6:
                      7: 1. Unzip the archive, preserving folder names so that the directory
                      8: structure is correct. I use WinZip to do this, and I put the files on my D:
                      9: drive, so that the files for pari-2.0.16.beta for example will be stored
                     10: under D:\pari-2.0.16.beta. Note that the archive as downloaded, pari.tgz,
                     11: is an archive of an archive. Winzip doesn't know how to unzip pari.tgz, so
                     12: I use Aladdin Expander to do this, which will create for example the file
                     13: pari-2.0.16.beta.tar in the same directory as pari.tgz. Unfortunately,
                     14: Aladdin Expander doesn't know how to unzip this file, so I use Winzip to do
                     15: it. Isn't Windows wonderful?
                     16:
                     17: 2. MSVC doesn't like names of the form "pari-2.0.16.beta", so rename the
                     18: base directory to something like "pari216b". Now the files are stored under
                     19: D:\pari216b.
                     20:
                     21: 3. Start MSVC (I use version 6, but earlier versions will probably work the
                     22: same way).
                     23:
                     24: 4. Select "File\New..." and pick the "Project" tab to create a new project.
                     25: Select "Win32 Console Application" as the project type, and specify the
                     26: project name as "pari216b". Make sure that the "Location" of the files is
                     27: D:\pari216b. Click "OK", then select "An empty project" (should be the
                     28: default anyway) and click "Finish".
                     29:
                     30: 5. Select "Project\Add to project\Files..." to add files to the project.
                     31: Select all the *.c and *.h files in src\basemath, src\headers,
                     32: src\kernel\ix86, src\language, src\modules and Odos, EXCEPT pariCE.[ch];
                     33: all of the files in src\gp except gp_rl.c; the files plotnull.c, plotport.c
                     34: and rect.h in src\graph.c; and the file src\kernel\none\mp.c.
                     35:
                     36: 6. Select "Project\Settings" and pick the "C/C++" tab. Select
                     37: "Preprocessor" from the "Category" menu, and enter
                     38: "D:\pari216b\src\headers,D:\pari216b\win32" into the "Additional include
                     39: directories" box. (I also select the "Code Generation" category and change
                     40: the "Struct member alignment" to "1 byte", but this may not be necessary.)
                     41: It is usually convenient for debugging to select the "Debug" tab and
                     42: specify a "Working directory", e.g. "D:\gp" if you have .gp files there
                     43: that you can use for testing.
                     44:
                     45: You should now be able to build and test the program. When you want to
                     46: build a release version, you will have to repeat step 6 above, since MSVC
                     47: doesn't apply the project settings globally.
                     48:
                     49: A couple of points:
                     50: -------------------
                     51: You may get some inconsequential warning messages. You can suppress these
                     52: by adding a line of the form:
                     53:
                     54:    #pragma warning(disable: ...)
                     55:
                     56: to paricfg.h, where ... is a space-delimited list of warning numbers, e.g.
                     57: "4018 4244" corresponding to the warnings C4018 and C4244.
                     58:
                     59: When you compile a release version, global optimization is enabled by
                     60: default. MSVC is fairly buggy with global optimization, so you may find
                     61: that some modules won't compile with it, e.g. sumiter.c. You can either
                     62: disable global optimization (in "Project\Settings" under the tab "C/C++" in
                     63: the category "Optimization"), or you can surround the offending code with:
                     64:
                     65:    #pragma optimization("g", off)
                     66:    ...
                     67:    #pragma optimization("g", on)
