C++ Maya Plugin Environment Mac

[Soham Parmar]

Hi,

I am trying to create node with cpp, I have never tried this before.

I am getting error while compiling I don't know what mistake I am doing, I think I am getting linker error.

below is the drive link for my folders and cmakeFiles. (I have reduced folder structure. and I am using cmake file which chad has provided on git.)

I am attaching my build log file to understand the error I am getting.

Any help would be really appreciated.

Thanks in advance.

Is that your complete CmakeLists.txt file? Have you tried using MAYA_LIBRARIES instead of MAYA_LIBRARY as the linker library variable?
Have you tried using this as a more complete reference?

Since Maya 2018 or so, each devkit example ships with a CMakeLists.txt file which takes much of the hassle out of the way.

Here's the gist of it.

```bash

cd /path/to/mayadevkit

export DEVKIT_LOCATION=$(pwd)

cd devkit/plug-ins/footPrintNode

mkdir build

cd build

cmake .. -GNinja

cmake --build .

```

And presto, about 2 seconds later you've got a Maya plug-in built. From there, you could search for `DEVKIT_LOCATION

(Accidentally posted too soon)

..from there, you could search for DEVKIT_LOCATION in the devkit folder to find out how Maya supplies some helper files you can either build upon or copy/paste to customise for your own custom builds. They’ll tell you about some of the variables relevant to various platforms and what suffixes they use for the built plug-in etc.

With that, I haven’t needed to search online for tutorials on how to build anymore, so I would wipe what you know from pre-2018 and start from there. :)

Hope it helps!

Thank you so much your help guys.

I have managed to build plugin I changed link_directories to link_libraries and it worked.

Now I opened Plugin-in Manager in Maya.

I simply browse to that path and loaded it. But I got this error in Maya.

// Error: file: /Applications/Autodesk/maya2018/Maya.app/Contents/scripts/others/pluginWin.mel line 909: Unable to dynamically load : /Users/soham/Downloads/mayaplugin/build/src/sampleplugin.bundle

I am trying to build same sampleplugin that is provided by chad on cgcircuit.


Hey Marcus,

I tried your way too. But got one question if you can help.

I created new build directory named and “build” I cd into that directory then I am running this command :- 

cmake .. -GNinja

But this is giving error saying CMakeLists.txt does not exists.

So I am confused what should I write in that CmakeLists file.

Thanks & Regards,
Soham Parmar.
