Executing 'make' command about gporca HOT 7 CLOSED

@d @oarap can u help here

from gporca.

Make sure you're building from a fresh checkout of git master, the way the platform-flags in config.h were set was broken between commits 76af819 and 3a0921d. That might explain the assertion on Backtrace.

You might also need to disable -Werror in the top-level CMakeLists.txt. I have to do that when building on my laptop, with a modern GCC version.

I had trouble getting it to run as well, I think it's necessary to use --with-libs in configuring gpdb afterwards to use the libs in /usr/local/lib

@VinnyPembe
Could you please provide the contents of CMakeSystem.cmake file from your gporca/build/CMakeFiles dir ?

from gporca.

We can't seem to reproduce your problem. We believe that your platform isn't being properly set in cmake. Can you provide the following to help us?

• Distro/OS versions (Centos 7)
• Compiler versions (GCC 4.8)
• Contents of CMakeSystem.cmake from somewhere under gporca/build/CMakeFiles
• version of ORCA you are trying to build, is it the latest?
• version of gp-xerces that you are trying link with ORCA, is it the latest?
• Steps for us to reproduce your issue

from gporca.

Please reopen issue if you need more help
