piecewiseyoyinflationcurve: compilation error using MS VC9 (2008)

[Ferdinando M. Ametrano-3]

Hi all

Compiling...
yoycapfloortermpricesurface.cpp
.\ql/termstructures/inflation/piecewiseyoyinflationcurve.hpp(127) :
error C2059: syntax error : '<'
        .\ql/termstructures/inflation/piecewiseyoyinflationcurve.hpp(130)
: see reference to class template instantiation
'QuantLib::PiecewiseYoYInflationCurve<Interpolator,Bootstrap,Traits>'
being compiled
.\ql/termstructures/inflation/piecewiseyoyinflationcurve.hpp(127) :
error C2238: unexpected token(s) preceding ';'

no problem using VC8

Go figure...  We can only try to move stuff around and see if it's more
digestible.  Try replacing the offending line

friend class Bootstrap<this_curve>;

with

typedef typename Bootstrap<this_curve> bootstrapper;
friend class bootstrapper;

Guys,

sorry for entering this thread, too, but

Compiling the "Bond" example breaks in exactly the same line with SUN CC:

"../../ql/termstructures/yield/piecewiseyieldcurve.hpp", line 149: Error,
notempname: A class template name was expected instead of
QuantLib::Bootstrap<QuantLib::Curve>.
"Bonds.cpp", line 214:     Where, temwhilespec: While specializing
"QuantLib::PiecewiseYieldCurve<QuantLib::Discount, QuantLib::LogLinear,
QuantLib::IterativeBootstrap<QuantLib::Curve>>".
"Bonds.cpp", line 214:     Where, temspecend: Specialized in non-template
code.
"../../ql/termstructures/yield/piecewiseyieldcurve.hpp", line 149: Error,
nofriendfield: A "friend" declaration must specify a class or function.
"Bonds.cpp", line 214:     Where, temwhilespec: While specializing
"QuantLib::PiecewiseYieldCurve<QuantLib::Discount, QuantLib::LogLinear,
QuantLib::IterativeBootstrap<QuantLib::Curve>>".
"Bonds.cpp", line 214:     Where, temspecend: Specialized in non-template
code.
2 Error(s) and 6 Warning(s) detected.

Changing to the above didn't help...

Rgds,

Andreas

Hmm. At least it worked for VC++9... may you try shuffling things around
and see if you get it to compile in some way?

The SUN compiler does not understand friend declarations using templated
classes.

A work-around that compiles, strangely enough, is to remove the "class" in

friend class Bootstrap<this_curve>;


I don't know whether you want to put this in the repository, though ;-)


Rgds,

Andreas

Only conditionally... Let's try to turn this into a configure test.
I've stripped the guilty file to a minimum and I'm attaching it to this
post. Can you check that if you run
    g++ -c test.cpp
(or whatever your C++ compiler is called) it does NOT compile, but it
does when you remove the "class" keyword?

Thanks,
        Luigi

P.S. Another try: does the original file compile if you keep the
"class", but replace this_curve in the friend declaration with the full
type? (Piecewise...<Interpolation,etc.etc>)

Will do.

I tried this already, and no, it doesn't...
