## I use the community engine plugin with engine, when I start my app, the server starts up with the following error: ## Attempting to copy plugin assets from ‘E:/r/iv\_2/vendor/plugins/community\_engine/assets’ to ‘E:/r/iv\_2/public/plugin\_assets’ WARNING: Couldn’t create the public file structure for plugin ‘community\_engine’; Error follows: Invalid argument - E:/r/iv\_2/public/plugin\_assets/community\_engine/E: Attempting to copy plugin assets from ‘E:/r/iv\_2/vendor/plugins/community\_engine/engine\_plugins/tiny\_mce/public’ to ‘E:/r/iv\_2/public/plugin\_assets’ WARNING: Couldn’t create the public file structure for plugin ‘tiny\_mce’; Error follows: Invalid argument - E:/r/iv\_2/public/plugin\_assets/tiny\_mce/E: Any idea?

Hi, I fixed this problem and submitted a test and patch for it on [lighthouseapp.com](http://lighthouseapp.com) over a month and a half ago. I’m not sure why it hasn’t been incorporated into the project yet, but here’s a link to the ticket on lighthouseapp with my patches in it. You can apply them using git-apply.

Dear Josh, I am not sure it is related with fftw\_wisdom\_file. Examining gri\_fft.cc I appreciate the wisdom is loaded when the gri\_fft\_complex and others are called. But this is not the case. Nevertheless I created the .gr\_fftw\_wisdom with fftw3f-wisdom tool and moved to APPDATA path. The warnings still remain as usual: Invalid argument. I used “grep -R “Invalid argument” \*” to locate this string in gnuradio and it does not appear in any place. So I guess it is with libraries. I bet it is with boost\_1.51. Thanks.

Moreover, I appreciate that for each session I start there is a file created with strange char name (&, , , ', and other rubbish), different for each session (so I have many of them). All of them contain “gr\_vmcircbuf\_createfilemapping\_factory, only this word. I guess maybe there is a sprintf(”%s") with rubbish, I do not know. Any guidance will be appreciated. Thanks. Pol H.
