Linux -fPIE build failure #32

Closed JMS55 closed 5 months ago

JMS55 commented 7 months ago

I get an error on Linux when linking against some kind of .rlib from libmetris_sys gklib.o

Looks like it's the force-optimize-vendor feature causing the problem. Disabling it compiles fine.

Also, weirdly, leaving it on but trying to use use-system has the same issue. I'm not convinced that use-system is working.

I'll try to reproduce it. Thanks for reporting it.

Fixed in #33.
