How can I surpress the message "warning: #pragma system_header ignored outside include file"
Issue
- Customer has encountered the warning message while compiling c++ source file.
-
Found that it happens after "#pragma GCC system_header" line
static const __int_type _S_app = (1); static const __int_type _S_ate = (2); static const __int_type _S_bin = (4); static const __int_type _S_in = (8); static const __int_type _S_out = (16); static const __int_type _S_trunc = (32); } ; } # 46 "/usr/lib/gcc/i386-redhat-linux/3.4.6/../../../../include/c++/3.4.6/cctype" #pragma GCC system_header # 49 "/usr/include/ctype.h" enum { _ISupper = 256, _ISlower = 512, _ISalpha = 1024, _ISdigit = 2048, _ISxdigit = 4096, _ISspace = 8192, _ISprint = 16384, _ISgraph = 32768, -
Following is the customer's compile environment and the actual warning messages
