set_soenv.in is the base for a perl program, executed during configure that generate Env.Host.sh
in turn Env.Host.sh (and Env.Build.sh in case of cross-compile) need to be 'sourced' in the shell... which lead to the need of some recurdsion magic in the Makefile. config_host.mk.in isthe base to generate a file config_host.k (and config_build.mk in case of cross compile). this file is designed in such way that it can be sourced in a shell _OR_ included directly in a Makefile. The later option would alleviate the need to recurse The main issue involved in this conversion are: - set_soenv would 'undef' any variable that end-up with an empty value. Most of the build test of == "" and does not rely on ifndef, but still there are exceptions which can cause trouble during the conversion. (Note: supporting the undef behavior is quite painfull to do in a way that maintain the goal of being both source-able and include-able) - set_soenv do path modification (to deal with windows mostly). it is very easy to get confused as to when a PATH should be 'windows' like and when it should be unix like... this is not help by the fact that the dmake build system actually tweak things along the way... - set_soenv deal with PATH. managing that properly is quite painful... I have not even started to think how I'm going to do that (except that I probably will need a kidn of path_munge() function in configure.in so, if your build start to act stupid on master... that may be my fault :-)....
