Good afternoon, I've been trying to run OpenSCAD in a remote server running Ubuntu, which means I don't have access to the GUI and I have to do everything via the command lime. Everything looks fine on every end, but on execution, OpenSCAD crashes with the following error: ERROR: boost::filesystem::canonical: No such file or directory: "/home/example-user/.local/share" The SCAD file is built in runtime, and it makes use of a STL file and a PNG image, but all of them separately look good. I have tried taking all those files to my local Windows system and running OpenSCAD from the command line here, and it runs smoothly and generates the STL output almost instantly. Windows version is 2015.03-1, while the Ubuntu server version is 2015.03-1+dfsg-0.1~trusty1, which I imagine is pretty much the same. The only difference between the command and SCAD file used is that I changed the address from being absolute in Ubuntu to being relative in Windows. The command used reads as follows: openscad /home/[path]/bayern.stl.custom_1.scad -o /home/[path]/bayern.stl.custom_1.stl --render The SCAD file has the following content: union() { import(file = "/home/[path]/bayern.stl", origin = [0, 0]); union() { translate(v = [0.0000000000, -1.0000000000, 4.0000000000]) { rotate(a = [0.0000000000, 0.0000000000, 0.0000000000]) { scale(v = [0.1000000000, 0.1000000000, 0.0039370079]) { surface(center = true, file = "/home/[path]/3182a2c5454c7408e7032969b3a3aff8-97.png.png", invert = false); } } } } } Any ideas? I have censored the real paths of the files, but I can assure you that the path the error mentions isn't remotely close to the ones used. The only common part would be the name of the user after /home/, but the next two folders are non-existent as far as I know. I can't afford to do the OpenSCAD rendering by hand as this is supposed to be an automated process performed on demand to arbitrary STL and PNG files, with custom SCAD properties for each. I know the file names look odd, but they work well in Windows.

you didn't delete that directory did you? read this: http://askubuntu.com/questions/14535/whats-the-local-folder-for-in-my-home-directory I don't know if openscad uses that directory or not. but it may appear that it does. -- Extra Ham Operator: K7AZJ Registered Linux User: 275424 Raspberry Pi and Arduino developer *The most exciting phrase to hear in science - the one that heralds new discoveries - is not "Eureka!" but "That's funny...".*- Isaac.

Hm, no, I haven't deleted it. Since the user folder was created manually, the folder probably wasn't there from the start. I created the folder and the error stopped happening, so that was it. However, it appeared the process was killed by the system before finishing. I've found out that is because the server doesn't have enough resources, and once OpenSCAD reaches the limit, the system kills the process. A big part of that is because, while the input STL file is about 250 KB in size, the OpenSCAD-produced output weights 6 MB. Does anyone know how to reduce the quality of the produced mesh and therefore the STL size? Or maybe I should open a new thread with that question and close this one? -- View this message in context: http://forum.openscad.org/OpenSCAD-command-line-crash-in-Ubuntu-tp16196p16200.html Sent from the OpenSCAD mailing list archive at Nabble.com.

OpenScad produces ASCII STLs. If your source file is binary it will get a lot bigger. That doesn't affect resource use though. CGAL can use lots of memory to represent simple things when you start doing boolean ops. On 20 February 2016 at 16:24, Ilceren <ilceren@hotmail.com> wrote: > Hm, no, I haven't deleted it.
