[IBMiOSS] pyodbc install error

I'm trying (unsuccessfully) to install pyodbc. I posted this issue to Rvyer last week. I have gotten responses but no fix, so I'm widening my search.


I have these RPMs installed:
libgcc-aix.fat 6.3.0-24 @ibm/$releasever
libgcc_s1.ppc64 6.3.0-24 @ibm/$releasever
libstdcplusplus-aix.fat 6.3.0-24 @ibm/$releasever
libstdcplusplus-devel.ppc64 6.3.0-24 @ibm
libstdcplusplus6.ppc64 6.3.0-24 @ibm/$releasever
python3-devel.ppc64 3.6.8-1 @ibm
unixODBC.ppc64 2.3.4-2 @ibm
unixODBC-devel.ppc64 2.3.4-2 @ibm


Here's the error from pip3 (within a virtual environment & system-wide give the same error):
ld: 0711-317 ERROR: Undefined symbol: __gxx_personality_v0

----------------------------------------

The pyodbc team says those two undefined symbols are part of the C++ Standard Library, and would seem to indicate a problem with the build environment.


Any thoughts?
