Build Bug in wip-peg

Build Bug in wip-peg

[Noah Lavine]

Hello all,

It's been a while, but I just got the wip-peg branch from the main
repository and tried to build it. After doing "make clean && make", I
get this error:

Undefined symbols:
  "_rpl_open", referenced from:
      _scm_open_file in libguile_2.0_la-fports.o
      _scm_load_objcode in libguile_2.0_la-objcodes.o
      _scm_copy_file in filesys.o
      _scm_copy_file in filesys.o
      _scm_open_fdes in filesys.o
ld: symbol(s) not found

However, I do not get an error when I build the master branch. Since
wip-peg is based on the stable branch, I assume that some build change
between stable and master made it work on my system. Can anyone
suggest what that might be?

Noah

wip-peg is based on stable-2.0, not master.  Perhaps it was something
fixed later in stable-2.0.  Does the problem persist if you "git merge
origin/stable-2.0"?  If not, then we should probably rebase the branch
again.

It will be great when we finally merge this branch :-)

Oh yes, good idea. I didn't realize I had hit reply instead of reply-all.

I'm replying to the list now so at least it will get a copy of the emails. :-)
