I try to make my question more specific as follows. I want to add new code, which is already organized under a directory, say, test. I want to add the directory test to main.c file for ARM VMM, located at ~/projects/vm/apps/vm/components/VM/src/main.c. In the program, we want to refer to the sub-directories by relative path to the directory test. what is the easy to do that? How can we add the directory test to the search path so that we can include the header files by the relative path to the directory test, say include "test1/test1.h"? We tried to modify the makefile at ~projects/vm/apps/vm, but we have to add all the sub-directories, and there are problems for the files with the same name under different directories. As far as I know this is a limitation with the way CAmkES builds components. If you're adding a lot of code that doesn't need to deal directly with CAmkES connectors then you can work around this by adding the new code to a library and linking your component against the library. If your code must be in the component then you will have to just not have duplicate names. thanks Peng _______________________________________________ Devel mailing list Devel@sel4.systemsmailto:Devel@sel4.systems https://sel4.systems/lists/listinfo/devel
