Dejan, haval za tvoj trud. Tvoj primer mi deluje brez napak. Ko sem pa
poskusu stvar sprobat na mojem programu, je res nekako bolje(mi najde
knjiznico), sam mi pa javi eno čudno napako:
-----------------------------------------------------------
[root at luka root]# gcc comm.cpp -o comm -lukazi -L/root/
/tmp/cc45lJNT.o(.eh_frame+0x11): undefined reference to
`__gxx_personality_v0'
collect2: ld returned 1 exit status
-----------------------------------------------------------
A je možno to krivo, ker funkcije v knjižnici vračajo kazalce? Drugč mam
funkcije, ki so v knj., deklarirane še v headerju, katerega uporabljam
pri glavnem programu.
