# Psion's Firefox: 1.0, the version firefox_1.0.oe names, with all ten of
# their patches and their own mozconfig -- a trimmed embedded build with no
# mailnews, no composer, no MathML, no accessibility, no tests, and a minimal
# set of protocol handlers and image decoders. The tree is already patched and
# .mozconfig is already in place; this job does their do_compile and do_install.
#
# VersatilePB caps out at 256 MB of RAM and some of Mozilla's C++ files want
# more than that to compile, so put swap on the disk first.

# Build with gcc 3.4, not the chroot's default gcc 4.1. This is not a
# preference, it is what the device needs: the card carries libstdc++.so.6.0.3,
# which is gcc 3.4's C++ runtime, so a gcc 4 build would want a newer one than
# the image has. It also removes a whole class of failure -- a 2004 Mozilla
# tree trips gcc 4's stricter C++ repeatedly (a trailing `;` on an extern "C"
# block, an extern array of an incomplete type in NSS), and each one costs a
# build round. gcc 3.4 accepts all of it, as Psion's own toolchain did.
# Exporting these is not enough on its own: NSS ships its own build system and
# ignores them, so security/nss was still being compiled by plain `gcc` while
# everything else honoured the export. /usr/bin/{gcc,g++,cpp} in the chroot now
# point at the 3.4 versions (the 4.1 ones are kept as *.gcc4-orig), which is
# what actually makes this stick.
