# By Edrx, 2008jan22
# This is my script to make the tgz:
#   (find-es "blogme" "blogme3.tgz")
#   (find-sh "cd ~/blogme3/ && make")

# Usage: on linux,
#   cd ~/blogme3/; make
# on BSDs:
#   cd ~/blogme3/; make LUAOS=bsd
# on zumbi, a BSD box in the same net of persephone:
#   cd ~/blogme3/; make LUAOS=bsd ANGGBASE=http://10.1.0.101/TH/R/
# on persephone or angg (linux boxes with $S and external binaries):
#   cd ~/blogme3/; make S=$S testb

# Note: on macosx things are harder - we need to use LUAOS=macosx to
# compile lua, and different gcc flags (and maybe an environment
# variable?) to compile lpeg... and right now the gcc flags that I use
# for lpeg are hard-coded in the makefile, see the "lpegbuild" and
# "$(LPEGSO_)" targets below...
# This message shows flags that seem to work:
#   http://lua-users.org/lists/lua-l/2007-04/msg00589.html
# that is,
#   export MACOSX_DEPLOYMENT_TARGET=10.3
#   gcc -bundle -undefined dynamic_lookup -Wall -O2 -o lpeg.so lpeg.c

# (find-node "(make)Setting" "FOO ?= bar")
# (find-node "(make)Instead of Execution" "`-n'")
# (find-node "(make)Errors" "-rm -f *.o")
# (find-es "make" "environment")
# (find-es "lua5" "install-5.1.2")

# Note: LUASRC must be absolute (a directory).
# (LPEGSRC too?)
