Hi, I just merged some work to GIL's `develop` branch. This notably involves improvements to the testing infrastructure. Testing GIL is a bit involved, as it requires various backend libraries (PNG, JPEG, TIFF, etc.) to be installed. While the stand-alone testing works fine (https://github.com/boostorg/gil/blob/develop/.travis.yml#L304-L306), the integrated testing will thus fail, until the testing logic is augmented by the necessary instructions to a) install the prerequisites and b) invoke the build system with the appropriate flags (https://github.com/boostorg/gil/blob/develop/io/test/Jamfile#L13-L22) Thus my question: do we have any documentation that explains how to do this ? What do I (as GIL maintainer) or any testers need to do for the integrated testing to work ? (I can't resist: all these libraries that have special requirements really shouldn't be built and tested in such a monolithic process. It's a burden to all tester, maintainers, and packagers. It would be far better to handle them more independently.) Stefan -- ...ich hab' noch einen Koffer in Berlin...
