[htdig-dev] Undefined symbols in OS X

[Jim C. <li...@yg...>]

Hi - I have a bit more information regarding the C++ related undefined 
symbols. The symbol names that show up as undefined match exactly those 
in OS X's libstdc++. So it looks like it is an issue of things not 
being found, rather than anything that is truly missing.

Additionally, I discovered that setting the DYLD_INSERT_LIBRARIES 
environment variable to the full path to libstdc++.dylib before running 
an ht://Dig program seems to solve the problem of undefined symbols. 
This variable is used to specify dynamic libraries that should be 
loaded before any specified directly by a program. I think it is 
primarily intended for testing, but it does seem to identify the nature 
of the problem. Apparently the current build system somehow fails to 
record a libstdc++.dylib dependency, resulting the library not being 
loaded at runtime.

All of the above holds regardless of the version of libtool used. Or at 
least for the current version and 1.5.
