I'm having an issue compiling using with the ilp32 compiler. Some free
functions, which should be in the std namespace, aren't namespaced.
Here's an example.
#include <cmath>
double round_wrapper(double val)
{
return std::round(val);
}
I get an error message that the round function isn't in the std namespace.
Calling return round(val); without the std namespace compiles successfully.
This is the command I used to compile
/opt/rtems/6/aarch64/bin/aarch64-rtems6-g++ -std=gnu++11 -D_GNU_SOURCE
-D__RTEMS_MAJOR__=6 -D__rtems__ -fno-strict-aliasing -mcpu=cortex-a53
-mabi=ilp32
-isystem
/opt/rtems/6/aarch64/bsps/aarch64-rtems6/xilinx_zynqmp_ilp32_zu3eg/lib/include
-qrtems -ffunction-sections
-fdata-sections -fPIC -o test.obj -c example.cpp
I tried a couple of revisions of rtems, the latest was aarch64-rtems6-g++
(GCC) 12.2.1 20220924 (RTEMS 6, RSB cfed1659a297cb0f95a03e053345962097aa02bf,
Newlib 01f6251c0)
if I try to compile the exact same code with similar arguments for arm
zedboard, it compiles successfully. So, something is different about the ilp32
compiler
/opt/rtems/6/arm/bin/arm-rtems6-g++ -std=gnu++11 -D__RTEMS_MAJOR__=6
-D__rtems__ -fno-strict-aliasing -mthumb -mfpu=neon -mfloat-abi=hard
-march=armv7-a -mtune=cortex-a9 -isystem
/opt/rtems/6/arm/bsps/arm-rtems6/xilinx_zynq_zedboard/lib/include -qrtems
-ffunction-sections -fdata-sections -fPIC -o test.obj -c example.cpp
I wasn't sure whether to send this to the bug email list, or to check here
first to see if someone noticed something I was messing up first.
Thanks,
Trip Richert
