Hello friends, I am new with Fedora 21 but I am trying to learn C++ as well. So, in my compilation command of "g++ -Wall `root-config --cflags --ldflags --libs` example.cpp" I am receiving the error message "/usr/lib/gcc/i686-redhat-linux/4.9.2/../../../crt1.o: In function `_start': (.text+0x18): undefined reference to `main' collect2: error: ld returned 1 exit status" After changing the compilation command to "g++ -ansi -Wall -I /usr/include -c example.cpp" I no longer receive the error. However during linking command "g++ -L /usr/lib/../../../ crt1.o *.o -lgsl -lgslcblas -lm" I receive the following error message "g++: error: crt1.o: No such file or directory" But, I know for sure that there is such a file. So, what could be wrong?
Thanks for everyone's help, Ashur
