Hello Robin, std_logic_textio is a Synopsys package. You need to use --std=08 to enable VHDL-2008, which includes this package or select another IEEE flavor with --ieee=synopsys. The latter one add vendor specific packages with are not Provided by IEEE to the ieee library.

Some of my code has includes the line use ieee.std_logic_textio.all; and if i call ghdl with $ ghdl -a *.vhd ./testbench/* i get the error ./testbench/tb.vhd:5:10: primary unit "std_logic_textio" not found in library "ieee". On my file system exist some std_logic_textio, which are from ghdl, I thought, but apparently the are not included correctly. I tried to specify the lib with the -ieee flag, but it didn't work either. What i'm doing wrong?
