Hacking gphoto2 and libgphoto2

Building gphoto2 and libgphoto2

Building gphoto2

Just to see what compiler options and so forth get used, after once doing a clean build of gphoto2, I made an innocuous hack to one of the source files (shell.c) and then typed make in the gphoto2 "base" directory. (Somewhere along the way I realized that I could just "touch" a file to change its mod time, but what is done is done at this point.

The real point of all this, dear reader, is to preserve all this gory detail for future reference, you most certainly aren't expected to wade through every option and compiler switch.

Lots can be learned here. In particular, note the invocation of the libtool shell script, which is quite a monster. Also note that when things like shell.c get compiled, they yield gphoto2-shell.o in some kind of effort to avoid namespace collisions. Note the -ljpeg and -lexif lines that drag in libjpeg and libexif.

Building libgphoto2

make a change to a camlib

Similarly, for libgphoto2, I go to libgphoto2-2.4.4/camlibs/canon and make a tiny hack to one file (library.c), then return to the libgphoto2-2.4.4 directory and type make to get:

make a change to libgphoto2 itself

The above gives only part of the story for libgphoto2, now lets add a silly one line comment to libgphoto2/gphoto2-library.c and then rebuild by typing make. This doesn't cause anything to happen! Something special about this file!!

I try again by doing touch libgphoto2/exif.c and then typing make, now this gives plenty of action:

clicksmart310

I am breaking this make output up into sections, it is so voluminous, the above is the really interesting part, but for completeness, there is indeed a lot more:

The rebuild triggers some weird dependency on clicksmart310, whatever the heck that is:
