Error while building cogutils for MOSES
EskenderTamrat opened this issue · comments
Based on the recent changes of the Opencog codebase, I think its possible to run MOSES separately from Opencog. But when I try to build the only prerequisite Cogutils, I encountered the following problem.

Any suggestions?
what compiler and OS are you using? the _GLIBCXX_USE_NOEXCEPT statement has been there since fore ver, not clear why its failing now.
whatever, I just pushed a fix that should solve this for you.
I encountered a slightly different error message with the new commit. I updated my compiler to 4.8, but had same error message. My OS is Ubuntu 12.04.

Thanks
what compiler version? 4.8.0? 4.8.1 4.8.4?
try gcc --version
Sorry for the late reply. gcc version is 4.8.1. I also tried with 4.9.2. But I am getting the following error

Can you take a look at exceptions.h and see what's going on? I tried to set it up in there so that _GLIBCXX_USE_NOEXCEPT got defined or undefined or whatever, done correctly for each differrent compiler, but i guess its not quite right. This should not be hard: take a look at the cogutil exceptions.h and compare that to the code in /usr/include/c++/4.6/exception:64:13: ...
whoa. I see a HUGE problem already: your compiler install is totally messed up! If you are using gcc-4.8.1 it should be pulling from /usr/include/c++/4.8 and NOT from /usr/include/c++/4.6 !!! That problem right there is enough to sink the battleship.
I'll take a look at the installation carefully. It seems all the time 4.6 has been used. I will get back to you, asap. Thanks, Linas.
