Hi David, Perhaps try the most basic set-up of PLplot first indeed. So no default drivers, only C bindings etc. The problem you are facing looks to be connected to your particular computer system, so let’s eliminate as many potential problem dimensions as possible.

The failure at the end of the example could indicate a problem with the driver rather than PLplot perse.

Again, the example ran but crashed upon closing. I cannot rule out that I've done something wrong. The more I try the more likely I am to go on auto pilot and miss something. I've got fairly detailed procedures for all these steps from help from the community, theh wiki, and the last time I had it working. I am trying my best to not deviate from the script with the exception of recommendations to try a fix. So far nothing has got me past this hurdle, though it seems like I'm close. On another front, I tried building up a MinGW Code Blocks system with plplot and widgets on a desktop and that ran into serious issues with a MinGW bug in stdlib.h. The recommended work around, provided by Vadim (widgets group) has not helped and I cannot get mingw64 to install. So it seems there is blockage at every turn. Are there any other places or things to check w/r to this ntdll.dll heap issue? David On 10/22/2019 9:47 AM, Phil Rosenberg wrote: I just opened up the example project you sent me. In project properties -> Linker -> Input -> Additional dependencies, the files listed should be .lib, not .dll. This is the case even when you build dlls. When Plplot is built, it creates a series of libs, who's job is simply to load the equivalent dll and pass function calls to that dll. These are commonly referred to as import libraries. They avoid having to call LoadLibrary() and GetProcAddress() in your code to grab the functions from the dll at runtime. I guess, basically, the import libraries contain the calls to LoadLibrary() and GetProcAddress(). There is a StackOverflow question about them at https://stackoverflow.com/questions/3573475/how-does-the-import-library-work-details<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstackoverflow.com%2Fquestions%2F3573475%2Fhow-does-the-import-library-work-details&data=02%7C01%7C%7C3c85af39cc224aafae3a08d757a1313e%7C15f3fe0ed7124981bc7cfe949af215bb%7C0%7C0%7C637074222147417329&sdata=DSrP3PiP2pqRz4SqeL9NlLlujV7RfXhiOsEm6ISUuuY%3D&reserved=0> Try swapping all your filenames from .dll to .lib and see where we gat to there. This may explain the corruption error - VS was loading the files expecting them to be libs, but they weren't.

I've been away with work and had a week laid up with flu. For your dll build. Can you open the plplot.sln. Where it says platform at the top, check it says x64. If you hit the drop down, the only option should be x64. [BD] Yes, everything was x64. How have you created the sln for the example? Did you do it manually or using the -DBUILD_TEST=ON option with cmake? [DB] I did it manually. If you did it manually then check the x64 is set in your example at the top when you open it in visual studio. [DB] Yes, x64 was the choice. If this doesn't work then try emptying your build directory and rerunning cmake including the test option from above. [DB] I did try that and having -DBUILD_TEST=ON causes the build to fail. Now when you open the plplot.sln file you will find a set of example projects in the solution explorer. Try right clicking and building one of these. Some other things you can try: Install dependency walker and run this on your example executable - it should show you the dlls it is using which might give you a clue. [DB] I'll give this a try. I've never used it. Try using the "where" command from the command line. Something like where plplot.dll Should list all instances of plplot.dll on your path. You may wish to run this from the working directory of your example - I'm not sure, but maybe it makes a difference. Hope that helps you make progress.

I really don't know why this has been so difficult. Based on some advice I received reaching out to the widgets and plplot user groups and my own review of my system I decided to completely delete my current plplot and wxwidgets builds and start over. This is for my Windows 8.1 laptop using VS 2017, x64. I also removed every occurrence of older versions of widgets and plplot even though I made sure they were not in the path. So I started with a completely clean system in this regard. I installed wxwidgets using the sln provided and that went without any issue. The I built and installed plplot using cmake followed by the sln without any trouble at all. I made sure both were built with the x64 (64 bit) option chosen so as to not mix 32 and 64 bit. Trying to build and run one of the plplot examples (x64 option) leads to the following: (1) dynamic linking causes a corrupt dll error (likely cause 32 and 64 mix, but I can't see how that is). (2) static linking works! but I still get a system crash upon closing the terminal. I cannot offer more than what I've provided in previous email threads. It seems that there are a few things I'm doing wrong but I just cannot see based on following the directions, or there is a bad combo of packages, SDK toolkit, and OS. Any suggestions would be appreciated. David On 9/9/2019 2:20 PM, Phil Rosenberg wrote: Corrupt file error sounds like you are mixing 64 and 32 bit exes and dlls. I think I've had that error with some libraries before and found that was my mistake. Is your install bin directory on your path? Do you have any old dlls somewhere that might be on your path? I usually use static libs. I used a dll version of wxwidgets about 6 months ago, so I know things worked back then. But I'm back to using static libs again. I will build a dll version of plplot this evening and send you exactly the commands I used.

Error LNK1107 invalid or corrupt file: cannot read at 0x310 plplotExamples C:\build-plplot-new-man\dll\csirocsa.dll 1 I am not sure what to do. Looking through some of the old blog posts of the issues I had last year it seems that is was also an issue then. When you do your build were you able to get everything using the sln or did you have to install at the command prompt too. That rings a bell and I think I wound up using nmake. Can you confirm your build/install procedure and perhaps shed some light on why csirocsa.dll would be corrupted? Thank you for your help.

Might be worth noting that I think the naming convention of the libs changed at some point. They used to have a d suffix to indicate using double precision. This has been dropped I think. So you might need to update the lib names in your project.

But I still got an install error in the IDE (sent in a previous email). You had suggested that perhaps I didn't build widgets using 64bit so I decided to purge everything and start over. I built the widgets files using their sln with x64 set. Then built plplot with cmake no problem and widgets was declared ON as expected. Using the IDE and the sln to INSTALL led to hanging and errors three times in a row. After the 3rd time I just looked in the folders and figured if I can find everything I might be okay. My recollection is that this happened last time too (back in 2017). The example I was trying to run was a simple one of my own that plotted various 3-dim mesh surfaces. I did not try to build the official plplot examples yet. Perhaps I should try that first. I don't know if what I've written is helpful in helping you help me get it working.

Basically every plplot function I call seems to cause this. A few example are provided. plAlloc2dGrid and all the plstream functions like box3, col0, font, etc. Typically what I cause this it's due to a function declaration in a class that is not defined elsewhere. It "seems like" my new build has the same files as the old one and the projects are comparable (with only diffs being the location of the new folders). Thanks in advance for your help.
