Hi,
given the following code:
-- isystem_test.cpp -------------
#include < isystem_test.h>
bool dummy_function( void )
{
return false;
}
-----------------------------------------
-- isystem_test.h ------------------
template <class _CS_cT>
class allocator
{
};
-----------------------------------------
and g++ version: arm-eabi-g++.exe (Linaro GCC 7.2-2017.11)
1. compiling with "arm-eabi-g++ -I . -g -c isystem_test.cpp"
--> OK
2. compiling with " arm-eabi-g++ -isystem . -g -c isystem_test.cpp "
--> output error:
In file included from isystem_test.cpp:3:0:
./isystem_test.h:3:1: error: template with C linkage
template <class _CS_cT>
^~~~~~~~
It seams that the option -isystem changes the include of isystems_test.h into a
C include, i.e. the header content seems to be handled as C-Code
Same error behavior with arm-eabi Linaro GCC 6.4-2017.11, Linaro GCC
6.3-2017.05
-----------------
Testing the same with the mingw msys g++ compiler outputs no error:
g++.exe (Rev2, Built by MSYS2 project) 7.2.0

Also no errors for:
arm-linux-gnueabihf-g++.exe (Linaro GCC 6.3-2017.05)
---------------
Is there a special behavior for arm-eabi g++ compiler?
Best regards
Martin Kaul
