The issue is due to missing support for inline namespaces:
namespace a {
inline namespace b {
struct foo {
static int bar() { return 0; }
};
}
}
int main()
{
return a::foo::bar();
}
This compiles fine but shows the same issue as std::chrono. Note that most of std::chrono from GCC is wrapped in an inline namespace _V2.

C++11: Add implicit using directive for inline namespaces. This fixes association of uses etc. to contents in inline namespaces, which is the case for e.g. most of the stuff in std::chrono. Note: Code completion of items in an inline namespace nested in another namespace (such as is the case for stuff in std::chrono::_V2) does not show up properly yet.

Committed on 20/10/2013 at 16:35. Pushed by mwolff into branch 'master'. Also take namespace imports into account for code completion after :: This should solve quite a few other related code completion issues. Note that this code was there already for the "global" code completion, but as soon as you picked a namespace from the list, you'd loose all imported items.

I recently updated KDevelop to 4.5.1 and gcc to 4.8.1. After that KDevelop complains in the Problems tab that the aforementioned class is not found. This didn't happen with KDevelop 4.5.0 and gcc 4.8.0 (unfortunately I updated both at the same time, so I cannot say which change lead to the problem). The example code in the "Additional Information" text field below shows the problem. Reproducible: Always Steps to Reproduce: 1. include chrono 2. use std::chrono::steady_clock 3. switch to the problem reporting tab Actual Results: Semantic Analysis: Declaration not found: std::chrono::steady_clock::now Expected Results: <nothing in the problem tab> #include <chrono> int main( int argc, char *argv[] ) { auto time{ std::chrono::steady_clock::now() }; return 0; }
