https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204329 Bug ID: 204329 Summary: clang++ does not resolve reference to STL member function Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: egilb@ife.no Created attachment 162848 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=162848&action=edit Shell script for compiling test-snippet The one-line c++ main function #include <string> template < typename T > int f( T ); int main() { return f( &std::string::c_str ); } should have only one unresolved reference. The clang-compilers available on FreeBSD 10.2 does not instantiate the STL member function. Gcc installed from the ports collections seems to do it correctly. A script compiling the source code shown above is attached. The result is, when trying gcc and different versions of clang compilers: FreeBSD gcc version 5.2.0 (FreeBSD Ports Collection) undefined reference to `int f<char const* ... FreeBSD clang version 3.4.1 (tags/RELEASE_34/dot1-final 208032) 20140512 undefined reference to `std::__1::basic_st ... undefined reference to `int f<char const* ... clang version 3.6.2 (tags/RELEASE_362/final) undefined reference to `std::__1::basic_st ... undefined reference to `int f<char const* ... clang version 3.8.0 undefined reference to `std::__1::basic_st ... undefined reference to `int f<char const* ... This behavior was not experienced when llvm/clang was installed from the source code on a Linux computer ( CentOS 6.2, clang installed as described on the web page https://github.com/rsmmr/install-clang ): Linux gcc version 5.2.0 (GCC) undefined reference to `int f<char const* ... clang version 3.4.1 undefined reference to `int f<char const* ... -- You are receiving this mail because: You are the assignee for the bug.
