I tried that, the build process went along a lot more smoothly but now I have a problem when I run a program, a window pops up saying debug assertion failed

File: f:\dd\vctools\crt_bld\self_x86\crt\src\fprintf.c
Line: 55

Expression: (str != NULL)

If I try to debug I get taken to this chunk of code in plcore.c

            pldebug ("plInitDispatchTable",
                     "Opened driver info file %s\n", name);
            while (fgets (buf, BUFFER2_SIZE, fd) != NULL)
                fprintf (fp_drvdb, "%s", buf);
        if ( buf [strlen (buf) - 1] != '\n' )
            fprintf (fp_drvdb, "\n");
        fclose (fd);

and the debugger points to the line fprintf (fp_drvdb, "%s", buf);

please use the command line which is available if you go to Start->Microsoft Visual ....->Tools. I hope you know what I mean, since I don't know exactly how the programs menu looks like in Vista. Please test if nmake is available (just enter nmake), if not run vcvars32.bat, then nmake should be available. Then configure plplot with

cd builddirectory
set PATH=builddirectory/dll;%PATH%
cmake -G "NMake Makefiles" -DBUILD_TEST=ON path_to_plplot_src

examples should be in examples/c and should run.

1) cmake can build Visual C++ projects, but they are not tested and very likely don't work as you found out
2) You need to tell the system where it can find dynamic libraries, therefore you need to add the dll folder to the PATH environment variable

Alternatively you can configure plplot for Visual C++ projects like this:

"cmake -G "Visual Studio 9 2008" -DENABLE_DYNDRIVERS=OFF pathtoplplotsrc

This tells cmake to build a shared library but all drivers are linked into the plplot library instead of each driver in its own dynamic library. This might cure your problem (but very likely not).

(BTW1: NEVER do the build in source directory. Create a build directory instead and tell cmake where the source is).

(BTW2: Instead of running Vista on your laptop you should have installed VirtualBox and installed Vista or XP as a virtual machine. The virtual machine actually runs quite at full speed, but compiling is slower since I/O is not that good in Virtual box.)

This email I wrote from my mind, so some things maybe not completely correct.

Good Luck,

Not more than 24 hours ago I had Ubuntu on my laptop and everything was fine but my work requires the use of a lot of windows programs so I formatted the hard drive and put Vista on the laptop.  Since then I've been trying futilely to get plplot to work in Visual Studio 9 2008.

I extract the plplot source and go to the folder in the visual studio command prompt and give the command, "cmake . -G "Visual Studio 9 2008""  That gives me an error saying ifort can't compile a simple test program but I don't have ifort so I guess that makes sense, if I give the command a second time it works fine.  Then I open the solutions in Visual Studio, once again I get a complaint about the fortran component but everything else seems to work fine.  Now if I build ALL_BUILD all but one of the projects work fine and visual studio tells me this.

I seem to have all the files I need to make a program with plplot but I I try that(in visual studio) the program tells me this.

plInitDispatchTable: Could not open drivers directory, aborting operation
