ld returned 1 exit status

[Anonymous]

Hi,

   

      I have a project with a number of files in subdirectories and a main holding it all together.  I have added a new c & h file in a new directory and when I try to build I get the above error on link.  There are no errors in any of the compiles. This is the output of the link line and the only error is the ld error.

   

Why is the main.o in there twice and is that the problem ?  How would I fix that ?

   

Thanks for the help

Can you try a clean build? When the file format of  main.o is not regocnized it might just be corrupted somehow...

Fixed it !!

   

main.c was getting compiled twice (see above) and the build was failing. To fix it. (1) Removed main.c/main.h from the project (2) Cleaned and re-built the project (this would fail). (3) Put main.c and main.h back into the project.  Then it built fine.

   

Thanks for the help
