Hi
Have just installed the gccUpdate from apple and ProjectBuilder no
longer links code which uses the complex number libs.

I have tried including both 3.1 and 3.3 libstdc++.a files but I get the
same error...

ld: Undefined symbols:
___dv__H1Zd_RCt7complex1ZX01n1_B0
___t7complex1Zddd
_cos__H1Zd_RCt7complex1ZX01_B0
_cosh__H1Zd_RCt7complex1ZX01_B0
_exp__H1Zd_RCt7complex1ZX01_B0

_sin__H1Zr_RCt7complex1ZX01_B0
_sinh__H1Zr_RCt7complex1ZX01_B0
_sqrt__H1Zr_RCt7complex1ZX01_B0

The readme stated that installing the update shouldn't make any
difference to ProjectBuilder compiles, I'm not convinced :-(

The symbols you quoted look like 2.95 based mangling of c++ symbols, not 3.x based.
Make sure you are compiling with the compiler you want to compile with, 2.95 is not
that good.
You can tell if you compiled with a 3.x based compile they will have _Z at the
beginning of the symbol.

Thanks,
