запускаю компиляцию: $ g++ -lusb balans.c -o balans получаю: /tmp/cca4sxGE.o: In function `main': balans.c:(.text+0xb1e): undefined reference to `libiconv_open' balans.c:(.text+0xb5d): undefined reference to `libiconv' balans.c:(.text+0xc97): undefined reference to `libiconv_close' collect2: ld returned 1 exit status Что нужно поправить в исходном тексте? Текст прилагаю. И.П.
