Hi, I build Haiku with development tools (gcc etc) by adding "AddOptionalHaikuImagePackages Development ;" to UserBuildConfig. It worked well previously. But, it seem not to work in GCC4 / GCC2 hybrid environment. Are any additional settings required? My Haiku revision is r25653 and Compiler version is GCC 4.1.2. My UserBuildConfig is attached. I build Haiku in haiku/trunk/generated-gcc4 directory.
