Bug #: 51486
Summary: g++ doesn't implicitly search for <decimal> header in
system include path include/c++/<version>/decimal/
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
The following testcase fails when compiled without specifying the explicit
include path for the decimal/decimal header:
decimal.cpp
---------------------------------------------------------------------------
#include <decimal>
using namespace std::decimal;
int main() {
decimal64 d64;
decimal128 d128;
/* extendddtd2 */
d128 = d64;
return 0;
}
$ /opt/at5.0/bin/g++ -m64 -O0 decimal.cpp -o decimal
decimal.cpp:1:19: fatal error: decimal: No such file or directory
compilation terminated.
When the include path is included explicitly compilation works fine:
$ /opt/at5.0/bin/g++ -isystem /opt/at5.0/include/c++/4.6.2/decimal/ -m64 -O0
decimal.cpp -o decimal
Here's the version information for the compiler:
$ /opt/at5.0/bin/g++ -v 2>&1 | grep version
gcc version 4.6.2 20110919 (Advance-Toolchain-5.0-1) [ibm/gcc-4_6-branch
revision 181060] (GCC)
I'm operating under the assumption that #include <decimal> should pick up the
include/c++/4.6.2/decimal/decimal header automatically without having to
specify -isystem on compiler invocation.
