Hi, While working on the “reproducible builds” effort [1], we have noticed that glfw3 could not be built reproducibly. The attached patch changes the value of HTML_TIMESTAMP in upstream's doxyfile to NO. Once applied glfw3 can be built reproducibly in our current experimental framework. Patching upstream doxyfile is necessary in this case because of the following reasons: 1. Even though the doxygen upstream changed the default value of HTML_TIMESTAMP from YES to NO this does not affect this package because the value of HTML_TIMESTAMP is explicitly set to YES. 2. Upstream's doxyfiles cannot reliably be modified to change the value of HTML_TIMESTAMP during the build process because dh_doxygen is only run after the build already completed and even adding a new dh command cannot solve the problem because there exists no sane and reliable solution to detect the file which will be used as the configuration file for doxygen (it is not always called doxyfile). 3. In case of this source package a patch against upstream is necessary in contrast to a patch against Debian rules because this source package does not call doxygen in debian/rules. Please also consider forwarding this patch upstream. Cheers! akira [1]: https://wiki.debian.org/ReproducibleBuilds
