gphoto-suite

gphoto-suite is a kind of umbrella package which contains required (sub)packages related to libgphoto2 in one convenient package.

gphoto-suite makes compiling and installing from scratch easier for

  • people without much compilation experience
  • people who use cross compilation environments
  • people who run test builds and runtime tests
  • people who build integrated binary packages of libgphoto2 and gphoto2

Legal stuff:

gphoto-suite includes multiple packages which are mostly licensed under GPL or LGPL. See the respective packages in src/* for details.

Quick Start:

This part is still to be written for the new git based setup which replaces the old svn based one.

Getting the source code via git

Sources:

[email protected]:gphoto/gphoto-suite.git
https://github.com/gphoto/gphoto-suite.git

Get the sources:

git clone --recursive [email protected]:gphoto/gphoto-suite.git

If you forgot the --recursive argument to git clone:

git clone [email protected]:gphoto/gphoto-suite.git
git submodule update --init --recursive

For git amb, clone and install ndim-git-utils from the following place, and then use git amb:

git clone https://github.com/ndim/ndim-git-utils.git

cd gphoto-suite
git amb make distcheck
ls -l _build/master/*.tar.*

If you have to make changes to src/gphoto-m4, src/gphoto2, src/libgphoto2 and push those upstream, change to the respective directory and make sure that you actually have a git HEAD (not a detached head).

Make sure required (or optional) dependencies are installed:

Highest importance: pkgconfig libusb-dev libexif-dev libjpeg-dev libpopt-dev libltdl-dev

Recommended: libreadline-dev

Less important: doxygen

Optional: libaa-dev

Configure the build system:

This step is required regardless of the method you used to get gphoto-suite.

Run

./configure --help=recursive

to get help on all the parameters for subprojects.

Note that some subproject options will be automatically set by gphoto-suite. This mostly concerns the *_CFLAGS and *_LIBS for the libraries gphoto-suite provides by itself.

Then run (for an in-tree build)

./configure

with your favourite configure parameters. Or, for an out-of-tree build:

mkdir ../gphoto-suite-build
cd ../gphoto-suite-build
../gphoto-suite/configure ...

with your favourite configure parameters.

If need be, you can even build the included subprojects by themselves:

mkdir ../libgphoto2-build
cd ../libgphoto2-build
../gphoto-suite/src/libgphoto2/configure ...

Compilation:

Use the standard commands:

make
make install

The latter may be given a DESTDIR= parameter or run as root.

Cross-compilation:

This is an example using i586-mingw32msvc as the system for which you want to compile (i.e. i586-mingw32msvc-gcc will be the compiler). The build system for this example is i686-pc-linux (you can run config.guess to determine the build system).

Note that you may want not to use

../configure --prefix=/foo/bar/usr ...
make all
make install

but

../configure --prefix=/usr ...
make all
make DESTDIR=/foo/bar install

if you have the "root" (/) directory of the system the stuff is supposed to run on mapped into /foo/bar. It depends on your setup.

You can build gphoto-suite for that platform by running:

mkdir _win32 && cd _win32
../configure --prefix=/tmp/lt-win32-inst \
    --host=i586-mingw32msvc --build=i686-pc-linux
make all
make install

If you have an emulator properly installed for the binaries, even make check will give results. Yes, you can compile and test Windows binaries on a Linux system!

Run the tests:

Run

make check

and examine the output.

Check the distribution mechanism:

Run

make distcheck

and see whether it finishes without errors.

Reduced driver build

For a quick make distcheck, it can be advantageous to not build all camlibs and iolibs:

make BUILD_THESE_CAMLIBS="directory.la" IOLIB_LTLIST="disk.la" distcheck

Adding a -j3 or similar might also speed up things.
