llvm-config problem under Ubuntu 13.10 about nvc

[nickg]

Can you find the relevant bit of config.log which has the error message? The following should do it:

grep -A 5 "checking for LLVM" config.log

I tried configuring on Ubuntu 3.10 but ran into a different problem (fixed above).

In your case it hasn't captured any output from llvm-config. Did you run configure with --with-llvm=...? Can you try without it after doing a git pull to get the above change?

[tmeissner]

I did run configure with and without --with-llvm=... with your new patch included but nothing changes. I don't understand why there is no output of llvm-config, because the tool is there and in the $PATH.

[nickg]

You may need to run ./autogen.sh again to regenerate the configure script

[tmeissner]

Now configure runs. So, when doing make I get the following:

Making all in thirdparty
  CC       fstapi.o
  CC       lz4.o
  AR       libfst.a
  CC       lxt_write.o
In file included from .././../thirdparty/lxt_write.c:24:0:
.././../thirdparty/lxt_write.h:37:19: fatal error: bzlib.h: No such file or directory

which can be fixed by installing the libbz2-dev package.

Then it runs until this error:

AR       libnvc.a
  CC       nvc.o
  CXXLD    nvc

[nickg]

Can you try again after pulling and re-running autogen.sh, etc.?

[tmeissner]

Now it works and all tests are passed. Thanks :)
