Co wyrzuca mi błędy:

C:\Users\User\Documents\Cpp\Projekty\FTP Download\main.cpp|13|warning: ignoring #pragma comment |
obj\Release\main.o:main.cpp|| undefined reference to InternetReadFile@16'| obj\Release\main.o:main.cpp|| undefined reference to InternetCloseHandle@4'|

||=== Build finished: 4 errors, 1 warnings ===|

O co chodzi ???
Program ma za zadanie wywołany z wiersza poleceń np. "FTP_download.exe www.google.com C:\Users\User\Desktop\plik" pobrać plik do wybranej sciezki HELP

C:\Users\User\Documents\Cpp\Projekty\FTP Download\main.cpp|13|warning: ignoring #pragma comment

Kompilator GCC nie obsługuje #pragma comment lib.
Musisz dodać bibliotekę do opcji linkera (zapewne w postaci -lwininet)

Dziękuję już wszystko działa :D
