Re: Build/Makefile question

[Caroline Tice <cmtice at google dot com>]

Ok, here are the patches for the Makefile.am and Makefile.in files.  I
am also having trouble with the following issue:  I need to make sure
that one of the new libraries is linked in with libstdc++ when
libstdc++ gets built.  I have not been able to successfully figure out
where exactly is the command that builds & links libstdc++.so.* (yes
I've looked at the build; it's being built with libtool somewhere,
somehow, and no matter where/how I specify the link flag to link in my
new library, the libtool link command is not picking it up).
