# 21-Jan-2016:
# Remove LLVM.  I cannot get llvm to build when llvm was present during the building of the
# gcc package.  Removing llvm before building gcc makes llvm build again.
#removepkg llvm

# Ensure the kernel headers package is installed.  These should always be installed
# but it doesn't hurt (unless you're in the middle of building something else)
# to do this:
ORIGPATH=$PWD # store this location because we change to /usr/include below
#( cd /usr/include
#  rm -rf linux asm-arm asm-generic asm
#  removepkg kernel-headers
# Incase I ever forget and delete them from the main ARMedslack tree, I've copied a working Kernel
# headers from Linux 2.4.26.  In the past I have found 2.6 headers break building gcc.
#  installpkg ~/tgzstash/d/kernel-headers-*.t?z
#  installpkg $ORIGPATH/arm/kernel-headers-2.4.26-arm-1.t?z
#  installpkg $ORIGPATH/arm/kernel-headers-2.4.26-arm-1.t?z
#  ln -s asm asm-arm )

# Launch the package build script:

( ./$PKGNAM.SlackBuild ) >& /dev/stdout | tee $BUILDLOG

# Compress the build log:
bzip2 -9fvz $BUILDLOG

# Restore the current autoconf:
#removepkg autoconf

# Reinstall llvm:
#installpkg $PKGSTORE/d/llvm-[0-9]*.t?z

# Do we need to rebuild llvm?
# Retry next gcc build with llvm installed and see if it works (didn't used to!)
