Update the build system, yet again. I hope this is the last time...
Here is the basic theory of operation: SHARED_LIB_LOADER_PATH/ <The location where the shared lib loader will be installed and where the compiler will cause apps to look for it.> DEVEL_PREFIX/ bin/ <contains gcc, ld, etc for setting PATH=$DEVEL_PREFIX/bin:$PATH> lib/ <contains all runtime and static libs> include/ <Where all the header files go> SYSTEM_DEVEL_PREFIX/ usr/bin/ <contains arch-uclibc-gcc, arch-uclibc-ld, etc that might be installed by a .deb or .rpm into /usr/bin, but can happily live under DEVEL_PREFIX> PREFIX This is prepended during 'make install's allowing you to shift things to be installed under some alternate location (such as when building a .deb) -Erik
