Hello
I have a the following code:
#include <vector>
class myClass {
private:
std::vector<Genode::Trace::Subject_id> mSubjectList;
public:
bool hasSubjectId(Genode::Trace::Subject_id aSubjectId) const {
return std::find(mSubjectList.begin(), mSubjectList.end(),
aSubjectId) != mSubjectList.end();
}
}
If I try to compile it, I get the following error:
/home/pirmin/Documents/genode/genode/contrib/stdcxx-fadf4f6ba436fe4846572f00bf057c5ef290c25b/include/stdcxx/bits/stl_algo.h:168:4:
error: passing ‘const Genode::Trace::Subject_id’ as ‘this’ argument of ‘bool
Genode::Trace::Subject_id::operator==(const Genode::Trace::Subject_id&)’
discards qualifiers
[-fpermissive]
In base/trace/types.h the signature of the operator==() for Subject_id
is defined as follows:
bool operator == (Subject_id const &other) { return id == other.id; }
Shouldnt it be?
bool operator == (Subject_id const &other) const { return id == other.id; }
Most recomendations on operator overloading, I have read, recommend this.
Best regards
Pirmin
