The issue is that PLPLOT_DRV_DIR is not recommended because it is typically not enough, and it is too easy to set it for the build tree when you need it for the install tree, etc. @Christiano: to understand what I say below, the build tree is where you build PLplot, and the install tree is where you install PLplot. Typically before you do a build you should remove any stale install-tree results and also any stale build-tree results, i.e., start from an empty build directory. After the build step, you typically install PLplot in the install tree (which typically copies just the subset of the files in the build tree that are actually needed for PLplot to work) and completely delete the build tree (to save lots of space). Here are the full Windows directions taken from the scripts/comprehensive_test.sh script (look for logic concerning ANY_WINDOWS_PLATFORM" = "true" ). _____________ If working with the build tree (and not the install tree): * Remove any install-tree PATH settings (see below). * Put the dll subdirectory of the build tree on your PATH. (This should give access to both device drivers and other needed dll's.) _____________ If working with the install tree (and not the build tree): * Remove any build-tree PATH settings (see above). * Put the install-tree bin subdirectory on your PATH. (This should give access to the non-device dll's.) * Put the lib/plplot[0-9].[0-9]*.[0-9]*/drivers subdirectory on your PATH (This should give access to the device dll's.) _____________ I don't have access to Windows at the moment so I cannot check the above directions directly, but Arjen tells me the comprehensive script approach works on Windows so the above approach should work even if you are not using that script. @Arjen: if your much larger experience agrees confirms what I have summarized from the comprehensive test script, could you adjust the wiki appropriately? For example, <https://sourceforge.net/p/plplot/wiki/Configure_PLplot_for_the_Visual_Studio_IDE/> says even in the build tree you need to set PLPLOT_DRV_DIR, but I am positive that is not necessary (and will potentially screw up working with the install tree after the build tree has been deleted). Also, could you double-check that it is actually required to put lib/plplot[0-9].[0-9]*.[0-9]*/drivers on the PATH or is that also old, unnecessary advice? If unnecessary, I will adjust the comprehensive test script approprately. Alan __________________________ Alan W.
