Hello, I clonned and installed caravel_user_project on Ubuntu 20.04 and now I wanted to run OpenRoad GUI from it. Could you please tell me what changes should I make to the makefiles to be able to run the gui (without having to install OpenRoad as standalone)? Thanks

Run following commands from OpenLane root folder:

@Vijayan Krishnan thanks, I tried that(make mount) but since I don't have openlane locally, I got the following error: Unable to find image 'efabless/openlane' locally docker:error response from daemon:Head

Copy code

export OPENLANE_IMAGE_NAME=efabless/openlane:latest
make mount
openroad -gui

Thanks but that didn't work.

Copy code

echo $OPENLANE_IMAGE_NAME
efabless/openlane:latest

And still the same error

Have you installed this tag

export OPENLANE_TAG=2022.07.02_01.38.08

export OPENLANE_IMAGE_NAME=efabless/openlane:$(OPENLANE_TAG)
make mount
openroad -gui

I got OPENLANE_TAG command not found error. But I have OPENLANE_RUN_TAG showing when try for example make user_proj_example in caravel directory. I tried exporting that too and same problem

If you installed caravel flow from here mean https://github.com/efabless/caravel_user_project follow, its should work

Copy code

export OPENLANE_TAG=2022.07.02_01.38.08
export OPENLANE_IMAGE_NAME=efabless/openlane:$(OPENLANE_TAG)
make mount
openroad -gui

If you're facing any other issue, it better to install standalone openroad is the solution

Thanks @Vijayan Krishnan! I didn't realize we could skip doing an independent openroad install 🙂 I was able to get this to work but I had to use the dependencies/openlane_src folder:

Copy code

export OPENLANE_IMAGE=efabless/openlane:<the tag you want>
cd <your caravel_user_project_wrapper clone>/dependencies/openlane_src
make mount
openroad -gui

I get some OpenGL errors but the gui appears to load:

Copy code

libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
