The project/application is built using make. make relies on special files called Makefiles. These are typically generated on the fly by ESbox so you won't have to bother understanding them.

In said Makefile, the pkg-config system is used. This enables you to ask for specific compiler flags. Have a look at how it works and you'll get it in no time.

To add flags by hand is easy too. Just copy and paste the compiler call in your terminal, add -llocation and press return. Tadah!

Allright, now we're getting somewhere... Thanks for the quick feedback everyone!

In my setup there are two "Makefile"-files, one in the source-folder "src", and one in the root folder of the project. I added
-I/usr/lib to the DEPS_CFLAGS-attribute and
-llocation to the DEPS_LIBS-attribute.

No more compilation errors after that regarding the undefined references.

Just remember that case matter. "-L" is not the same thing as "-l".

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.

That is understood, case matters.

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.

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.

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.)

I don't know esbox :-(, I can just guess. May it be, that esbox (or the
eclipse build environment) just generates these Makefiles. If you change
them your manual build may succeed but from within esbox or when
building the package they are re-generated and your changes vanish?

By the way, those compiler and linker flags are often set through pkg-config like
"pkg-config --cflags --libs liblocation".
Does esbox provide thome project settings where you can set dependency with
pkg-config?

I think that can be excluded, as the Makefiles are in the project folders and editable. The changes remain in the files after a build.


By the way, those compiler and linker flags are often set through pkg-config like
"pkg-config --cflags --libs liblocation".

I am looking for these settings, too, so I would just add my dependencies manually and be happy for the time being.

Currently it look as if I found a promising lead for this: In the "configure.ac" file I add "liblocation >= 0.1" to make it look like this:

Code:
PKG_CHECK_MODULES(DEPS, gtk+-2.0 >= 2.2 glib-2.0 >= 2.2 gnome-vfs-2.0 >= 2.2 liblocation >= 0.1)
AC_SUBST(DEPS_CFLAGS)
AC_SUBST(DEPS_LIBS)
No other files were modified, the previous modifications (see previous posts) to the Makefile were "undone".

It builds, I can create a Debian package, it installs on the N900 and it runs.

More testing to be done, though...

And this configure.ac file is most likely generated by ESBox using some list of libraries that will be needed for the project. To be forced to add a dependency like this by modifying the file by hand looks like a bug in ESBox.
