# Slackware SlackBuild script 
# ===========================
# By:          Eric Hameleers <alien@slackware.com>
# For:         chromium-dev
# Descr:       Open Source version of Chrome Web Browser (Development version)
# URL:         http://www.chromium.org/
# Build needs: - multilib gcc & glibc for compiling the Native Client (64-bit);
#              - libelf with '-D_FILE_OFFSET_BITS=64' added to CFLAGS (32-bit);
#              - libtinfo (provides symlinks required by downloaded clang);
#              - ninja;
#              - nodejs;
#              - gcc >= 5.4.0 unless you compile using clang
#              - Internet access (for downloading the nacl/pnacl toolchain bins)
# Needs:
