The error message in this case is misleading: $ cat foo.cc #include <unistd.h>
namespace foo { typedef long long offset_t; } using namespace std; using namespace foo; int main() { offset_t fpos; } $ $ g++ -c foo.cc foo.cc: In function `int main()': foo.cc:11: error: `offset_t' undeclared (first use this function) foo.cc:11: error: (Each undeclared identifier is reported only once for each function it appears in.) foo.cc:11: error: parse error before `;' token $ Actually 'offset_t' is declared twice, once in the global namespace in Solaris' <sys/types.h> and once in the foo namespace. -- Summary: error message is misleading Product: gcc Version: 3.4.3 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: papadopo at shfj dot cea dot fr CC: gcc-bugs at gcc dot gnu dot org GCC host triplet: sparc-sun-solaris2.8 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20401
