Comment(by was):
The fix is to replace the one instance (around line 2000) of
{{{
power::power
}}}
in src/ginac/functions.cpp with
{{{
GiNaC::power
}}}
This is evidently due to *better* checking of the proper namespace/scoping
rules in GCC-4.5.0.
I made the above change, and Ginac builds fine. Moreover, I ran this
code:
{{{
sage: 1/tan(x)
}}}
and
{{{
sage: derivative(1/tan(x)).integrate(x)
1/tan(x)
}}}
According to the print statements I inserted into functions.cpp, the code
that called power::power before is activated and is working correctly (no
weird infinite recursions or anything).
I'm hoping this can just be given a positive review by Burcin and the fix
rolled into the spkg at #8644, with a link from #8644 to this ticket.
