[Scons-dev] howto debug configure

[Neal Becker]

I have a lot working, but not configure.  I don't know how to debug it.

even with --debug=stacktrace, the stack trace is not useful.  I don't have
any idea where this error is coming from:

file <string>,line 92:
	Configure(confdir = .sconf_temp)
scons: Configure: Checking for C header file unuran.h... 
.sconf_temp/conftest_0.c <-
  |
  |#include "unuran.h"
  |
  |
scons: Configure: Caught exception while building ".sconf_temp/conftest_0.c":

Traceback (most recent call last):
