undefined reference to ....

[Ben Tay]

Hi,

regarding "> > > -lirc -lgcc_s -lirc_s -ldl  -o a.out global.o  main.f90"

is it the correct order? my make file is in that order.

anyway, compiling 1st then linking solve the problem. Strange that it didn't
work compiling/linking at the same step. it worked for other configuration.

thanks anyway.
