ld: Unsatisfied symbol _Unwind_** in file ....../libstdc++.a

[sjjung]

I'm trying to build postgis on hp-ux B.11.31 ia64, which requires gcc compatible for c++ 11, geos library and etc.

On building gcc and geos,  make crashes on the errors like this.

ld: Unsatisfied symbol "_Unwind_SetIP" in file /usr/local/ia64/lib/gcc/ia64-hp-hpux11.31/4.7.2/../../../hpux64/libstdc++.a[eh_personality.o]

9 errors.
collect2: error: ld returned 1 exit status

My gcc version is 4.7.2 currently, and I am trying to install gcc >= 4.9.

How can I solve the Unsatisfied symbol problem?
