Hi, I'm the maintainer of PTXdist [1], which is a build system for Embedded Linux projects. One of our aims is to provide patches for upstream packets, in order to make overall cross compilability better. Although most times autotoolized projects cross compile out of the box or can be fixed easily, there is a certain class of projects I've not found the right solution for: There are situations where generator tools are being run during the compile stage, which is no real problem if the generator tools are correctly built with CC_FOR_BUILD. However, especially with larger projects [2], people often build their own support libraries as a part of a project; now the problem comes in when generator tools need to link against this support libs; examples are - extra/comp_err in MySQL, linking against several freshly built libs - IDL compiler in TAO, which itself links against libace and others. Is there a standard solution for this kind of problem, or is there some project out there which can act as a good example howt do do that? At the moment we solve it in PTXdist by having two packets: one for the development host and one for the target system, and tweak the "build" architecture compiled files into the other tree, but that is no sane solution in the long term. It helps for our problem, but doesn' solve cross compilation for the upstream packets. Robert [1] http://www.pengutronix.de/software/ptxdist/index_en.html [2] e.g MySQL or ACE/TAO -- Dipl.-Ing.
