I am trying to learn how to do module stacking. I have a module named providesexport that exports the symbol "some_exported_symbol" which is a function. In another module called usesexport I call the exported function.
The code compiles and runs as expected, however I get the following warning when compiling the module that uses the exported symbol.
make[1]: Entering directory `/lib/modules/2.6.10-1.770_FC3/build'
CC [M] /home/tony/learnexport/user/user.o
LD [M] /home/tony/learnexport/user/usesexport.o
Building modules, stage 2.
MODPOST
*** Warning: "some_exported_symbol" [/home/tony/learnexport/user/usesexport.ko] undefined!
CC /home/tony/learnexport/user/usesexport.mod.o
LD [M] /home/tony/learnexport/user/usesexport.ko
Before compiling usesexport.ko, try loading providesexport.ko. The warning should go away.
