Portierung Linux-> MS VC++ STLs
-
Hallo,
ich versuche die VW34 (Oxford Vision Library) von Linux nach Windows zu portieren. Anscheinend macht dabei die Verwendung von Standard Template Libraries Probleme, hier mal ein Beispiel:
vectorfixed.h(178) : error C2143: syntax error : missing ';' before '<'

vectorfixed.h(187) : error C2334: unexpected token(s) preceding '{'; skipping apparent function bodyDa mir der Fehler leider absolut nicht klar ist hier der gesamte Quelltext:

Vielen Dank auch schon fuer das Lesen,

Der kennt MatrixFixed zum Zeitpunkt der Verwendung nicht. Mit einer STL hat das nichts zu tun.

Tja, da hatte ich wohl die entscheidenden Zeilen nicht zitiert:
#ifndef _WIN32 // VC++ can't cope with forward declaring templated namespace members template <int n, class T> class VectorFixed; template<int n, int m, class T> class MatrixFixed; template <int n, class T> VectorFixed<n,T> ElementProduct(VectorFixedRef<n,T> const&, VectorFixedRef<n,T> const&); template <int n, class T> VectorFixed<n,T> ElementQuotient(VectorFixedRef<n,T>const&, VectorFixedRef<n,T> const&); //#endifUnd irgendwie kannte der Praeprozessor wohl das Makro _WIN32 nicht.
Auf jeden Fall vielen Dank!

Could not find a suitable section so I written here, how to become a moderator for your forum, that need for this?
