« on: 02.12.2012, 00:07:05 »To test:
Ahoj. Skusal som pod ubuntu upravit si cviko 1 - kalkulacku. Najprv bolo nutne si nainstalovat cez apt-get install flex. Bison som instaloval podla navodu z netuAle asi aj ten sa da nainstalovat do ubuntu z repozitara.. Ok, tak na ukazku pripajam upravene subory CALC1.L a CALC1.Y v prilohe. Bolo ich nutne upravit, ale aj to som robil narychlo podla navodu z netu
1. yacc -d CALC1.Y
-- vytvori subor y.tab.h a subor y.tab.c
2. lex CALC.L
-- vytvori subor lex.yy.c
3. g++ y.tab.c lex.yy.c -lfl -o test
-- skompiluje program s nazvom test (sice s warningami - tie dnes neriesim
4. ./test -- spustenie kalkulatora
Ok, snad ma linuxaci nezastreliaNa dnes len tolko
cawte....pri kompilacii na linuxe mi vyhadzjue errory aj z *.L suboru (kompilacia na stiahnutom zip archive)
nejake napady?
