That is understood, case matters.

So, either you did a typo while you wrote the previous message or you actually added "-l/usr/lib" which makes no sense to the linker.

Well, that's where my lack of understanding of Makefile-files continues:
In the Makefile-file in the root folder are several CFLAGS- and LIBS-attributes: DEPS, HILDON and OSSO. And in those, the directories are referenced with "-I" (capital "I", not small "L") ?!? Now I don't know to which of these attributes to add the flags for the location directory, but believe it or not, by doing as per my previous post ESbox succesfully compiles.

Code:

make -k all "CFLAGS=-O0 -g" "CXXFLAGS=-O0 -g"

So, compiling in ESbox completes without error, but the program does not run in Scratchbox. And creation of a Debian package fails, too. And since GPS emulation is not possible in ESbox/Scratchbox, I do have to export to run it on a N900 device.

Console output for Debian package creation:

So, my questions are:

-Where exactly do I have to add the flags in Makefile and in which Makefile (/src vs. root)?
-How come it compiles locally but fails with the above error when creating a Debian package?
-Where to read on documentation about how to configure this in ESbox? (I assumed ESbox would automatically take care of things like that.)
