# gcc494/cfg - "Build" settings for package #--------------------------------------------------------------------- [technotes] 1. "gcc494" provides an old release of "gcc" (4.9.4). To use this release in a package, specify "compiler = gcc494" in the package's "cfg" file. To use this release to compile a 'C' program outside of the package context, try doing this to set up: PATH=$PRODTREE/gcc494/bin:$PATH #--------------------------------------------------------------------- 2. Presently, "gcc494" (gcc 4.9.4) is needed, and used, to build itself. If you're porting this distro to a new architecture, you may be able to use a different distro's copy of "gcc" 4.9.4 to bootstrap this distro's copy. The details are beyond the scope of notes at this le- vel. #--------------------------------------------------------------------- 3. This release of "gcc" isn't intended to serve as the default 'C' or C++ compiler for this distro. #--------------------------------------------------------------------- 4. The executables stored in this package's main "bin" directory shouldn't be compressed (i.e., using "upx" or a similar program). If this is done, the distro's compiler wrapper won't be able to operate correctly. It's also a bad idea to compress executables stored in this package's other directories. In theory, this should work. In practice, it pro- duces a slow compiler. #--------------------------------------------------------------------- [buildtimes] 00.18 hours (or 010.72 minutes) - 2023 dedi Xeon E3-1200 v3 4x2 32GB RAM 00.21 hours (or 012.78 minutes) - HP EliteBook 8560w 32GB RAM 00.22 hours (or 013.45 minutes) - ThinkPad W530 i7 4x2 32GB RAM 00.28 hours (or 017.05 minutes) - ThinkPad E540 i7 4x2 16GB RAM 00.38 hours (or 023.03 minutes) - ThinkPad W530 i7 4x2 32GB RAM using a 64-bit kernel and 32-bit distro #--------------------------------------------------------------------- [settings] altpkg = yes configure = none # Handled during "build" stage license = See "license*.txt" in installed tree licfile = COPYING nodebug = yes nosyslinks = yes # Disable normal integration nowerror = yes purge = no # This is a critical package tmpsize = 788M unpack = relaxed #--------------------------------------------------------------------- # Dependences are listed as forward, for this package, because this # package may need to be built initially using cross-compilation from # another distro.
