ABF without SuperLU?

[stephen-yee-adsk]

Hi,

I'm trying to use the ABF++ implementation in geogram via the geobox application. When I load a mesh and go to Surface > make texture atlas > use ABF, I get some errors:

Error: OpenNL error in nlOpenDLL(): Not implemented
Warning: Could not initialize SuperLU extension

From digging into the code a bit, it looks like the ABF code depends on the SuperLU extension for OpenNL?

Is there some way to make the ABF code work without this? (I'm on Windows)

Thanks!

Hello, you may need to compile geogram as a dynamic library (how to do that is explained here). Then it will also compiled the bundled SuperLU and OpenNL will see it and load it dynamically.

Thanks that worked!

Update: now (version in git and upcoming v1.9.3) geogram builds DLLs by default under Windows, so it should work without having to do anything special.
