Getting error while linking with g++


Getting error while linking with g++



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.
Displaying an image from the tmp directory
g++ -c -o file1.o file1.cc.
How do they read clusters/cylinders/sectors from the disk?

You should not be mentioning your header file on the command line - you don't want to compile it directly, but only as it is included in your source files.


Spring ResourceServlet throws too many open files exception in jetty and tomcat under linux
also, I would let the compiler name the object files, as it's too easy to make a typo when doing this explicitly.

So your compilation commands should look like:.
g++ -c file1.cc  
and you can then also say:.
g++ -c file1.cc file2.cc file3.cc
