QT5.12 Mesa on AM3352
-
I have build libdrm, mesa and qt5.12.3 to use mesa for an AM3352 without a graphics core. I have built mesa for software rendering. All of this was successful. Now it seems i am having an issue with libdrm and mesa. mesa seems to be looking for the tilcdc driver with a name tilcdc_dri.so and this is not a product when compiling libdrm. I am able to use modetest with mode set to tilcdc without issue and i can use qt5 with linuxfb. I cant really think of a way around the issue if mesa is looking for a specific driver that does not exist. Should i be renaming a libdrm driver? Here is the output.

I am seeing the same issue. Did you ever get this sorted?
