# Not quite ready to install: the PREFIX override doesn't entirely work
|
|
# because the st binary was built from st.O (obcpl's parsed syntax tree
|
|
# format) which has the /usr/local/lib path baked into it (not affected
|
|
# by the sed command, above). st.O is distributed this way because obcpl
|
|
# needs to be buildable on a system without an existing BCPL compiler. So
|
|
# we need to regenerate st.O from st.b (its BCPL source), then rebuild
|
|
# st from st.O. This works because st will look for its includes in the
|
|
# current dir first. This is the sort of thing gcc has 'make bootstrap'
