Applications may have several source files in different directories. These files may be accessed using links. This example shows how to create a link between the files.
Define the BYE flag by creating a bye.df file in your MYCOMP/src, including the following information:
DEFINES="-DBYE"
The bye() function will be called once the BYE flag is defined in the compilation options.
Remove the MYCOMP build directory and run make again as follows:
host% rm -rf /<work_dir>/build-MYCOMP host% make
The link phase fails because the bye() function in not defined properly.
Create a new directory (bye) in your src directory and define the bye() function in the bye.c source file by including the following information in the file:
void bye() {}
The bye.c file is not in the same directory as the .df file. You must create a .mf file, bye.mf, in your bye directory containing the following information:
C__SRCS = bye.c
Run make again and the link phase will succeed.
host% make
Note, the bye.o object file has been automatically added to the list of files used to link hello. To display this list, use the getExport command:
host% <bin_dir>/host/bin/getExport build-MYCOMP/src build-MYCOMP/src/bye/bye.o build-MYCOMP/src/hello.o
