It could be due to some configuration option in the configuration file that gets loaded automatically. On linux systems, this is typically $HOME/.fpc.cfg There is a very important switch that prevents loading those implicit configuration file: -n when confronted to some error with public sources, you should always check if adding -n to options does not change the outcome of your make run. Simply try to run make but adding -n to Free Pascal compiler options, simply by using make OPT=-n or make OPT="-n ALL_OPTIONS_YOU_USED_BEFORE" Please report if this solves the compilation failure for Free Pascal 3.0.4 sources for x86_64-linux.
