This error is a problem in the Makefile dependencies: do a "make Reductions.o" first, and then it should compile.

I also just committed a fix. Either do a git pull, or wait for tonight's update.

Hello,
I am still getting issues with compiling ChaNGa dev version. Does changa dev
version requires the dev version of charm++? Right now, I am using charm++
6.4.0.

Hi Shad,

Did you perhaps compile part of this with gcc-4.5.x? It comes
with a libstdc++ that has versions up to GLIBCXX_3.4.14. The
libstdc++ that comes with gcc-4.4.2 only has versions up to
GLIBCXX_3.4.13.

Thanks,

It seems that there is some issue with your standard C++
libraries. I
searched google for the error and got the following links
