Question

I try to compile and link my application in 2 steps :

Compiling:

g++ -c -o file1.o file1.cc general_header.h
g++ -c -o file2.o file2.cc general_header.h
g++ -c -o file3.o file3.cc general_header.h

Linking:

g++ -o myApp file1.o file2.o file3.o

I’m getting a link error as following:

file1.o: file not recognized: File format not recognized
collect2: ld returned 1 exit status

Am i doing something wrong ?

Thanks

No need to include header files in your input files list

g++ -c -o file1.o file1.cc
