The linker requires the name of the library where this function resides.
I fixed it by adding "-lmirclient" to the Makefile.
# diff Makefile Makefile-ORG

I had the same problem and I could not solve but I was using SDL2.0.3 and I did not face any problems and it worked and compiled with me You can install it here https://sourceforge.net/ projects / libsdl / files / SDL / 2.0.3 /

A quick fix is to set a static link to the mir library when running configure:
./configure --enable-mir-shared=no
This causes the variable to EXTRA_LDFLAGS
have a parameter -lmirclient
appended to it, as per Juan's answer.
For what the problem is, see bug 3539 , which was resolved in patch shortly after.
Looking at the patch shows the missing definition required to dynamically bind to the "mir_output_get_current_mode" function mentioned in the error message.
