dnl Advanced information about versioning:
dnl * "Writing shared libraries" by Mike Hearn
dnl http://plan99.net/~mike/writing-shared-libraries.html
dnl originally http://navi.cx/~mike/writing-shared-libraries.html
dnl * libtool.info chapter "Versioning"
dnl * libtool.info chapter "Updating library version information"
dnl ---------------------------------------------------------------------------
dnl Versioning:
dnl - AGE (Micro): Increment if any interfaces have been added; set to 0
dnl if any interfaces have been removed. Removal has
dnl precedence over adding, so set to 0 if both happened.
dnl It denotes upward compatibility.
dnl - REVISION (Minor): Increment any time the source changes; set to
dnl 0 if you incremented CURRENT.
dnl - CURRENT (Major): Increment if the interface has changes. AGE is always
dnl *changed* at the same time.
dnl
dnl To summarize. Any interface *change* increment CURRENT. If that interface
dnl change does not break upward compatibility (ie it is an addition),
dnl increment AGE, Otherwise AGE is reset to 0. If CURRENT has changed,
dnl REVISION is set to 0, otherwise REVISION is incremented.

dnl The goals here are twofold:
dnl
dnl * Produce as many compiler warnings as possible to find
dnl potential problems in our own code.
dnl
dnl * Make sure our API header files are as broadly compatible as
dnl possible.
dnl
dnl We want our library and driver code to compile with the lowest
dnl possible number of warnings, and the pedantic compilation tests to
dnl compile with zero warnings (-Werror) so we do not limit the users
dnl of our API in their use of compiler warnings.
dnl
dnl If, for some reason, you need to build without all these compiler
dnl warnings, run the build while setting CFLAGS to an empty string:
dnl
dnl $ make all check CFLAGS=
dnl --------------------------------------------------------------------
dnl * gcc exits non-zero when it encounters an unknown warning option
dnl * clang by default ignores unknown warning option

Please check whether the configuration I have detected matches what
you would like to have. E.g. make sure that USB support is there if
you intend to use USB cameras with ${PACKAGE_NAME}.
Please also check that PKG_CONFIG_PATH contains
${pkgconfigdir}
before compiling any libgphoto2 frontend.
