Hi, guys With your help, I know that I should do the following step for ilp32 support for obs: 1. Add ilp32 support for kernel(community patches), gcc(only bugfix) and glibc(community patches). 2. Add ilp32 support for rpm and its configuration files. 3. Patch open-build-service according to Jan's reply. And, I still know nothing about the whole picture. I search on google and get some link in opensuse build service, it seems that it could not solve my quesiton[obs_add_build_target][obs_crossdevelop] BTW: do you think it is worth to put this on the GSoC 2015 proposals?
