I am using a Wind River Compiler 4 (gcc (C) and g++ (C++)) and it compiles all my projects without any problems. Now I have to use Coverity Static Analysis to check my code. I have configured the specific compilers. For the C-Code (gcc) there are no problems and I can run the analysis, but for the C++-Code (g++) I got a lot of errors:
.../c++config.h", line 214: error #40:
expected an identifier
inline namespace __gnu_cxx_ldbl128 { }
^
.../c++config.h", line 214: error #326:
inline specifier allowed on function declarations only
inline namespace __gnu_cxx_ldbl128 { }
^
.../c++config.h", line 214: error #65:
expected a ";"
inline namespace __gnu_cxx_ldbl128 { }
^
.../include/string.h", line 76: error #312:
cannot overload functions distinguished by return type alone
extern __const void *memchr (__const void *__s, int __c, size_t __n)
^
.../include/string.h", line 116: error #312:
cannot overload functions distinguished by return type alone
extern "C++" __const void *memchr (__const void *__s, int __c, size_t __n)
^
It seem to be some C++11 specific features like the inline namespace but the code doesn't use these features. The errors above are produced with a HelloWorld-Code:
#include "stdio.h"
#include "util.h"
#include <string>
#include "string.h"
using namespace std;
int main()
{
printf("Hello World, C++ version: %d.%d.%d\r\n",__GNUC__,__GNUC_MINOR__,__GNUC_PATCHLEVEL__);
return 0;
}
I have tried to set the c++ standard with the g++ option
-std=c++98
but the result doesn't changed.
The Test-Code is in a big build hierarchy but the steps for Coverity are like this:
- target and env set (Wind River 4 Linux)
- make clean
- cov-configure with compiler dir and type
- cov-build with the correct "make all" command that works alone
- cov-analyze
- if (no_error) cov-commit-defects
I have also configured Coverity to replace all "inline namespace" with "namespace" during the cov-build (--ppp-translator replace/inline namespace/namespace
). The inline errors disappeared but it produces more of this overload errors and no succecfully build. Also tried to remove the "C++" the same way but didn't work there are always more errors.
Does anybody have an idea what is the problem here? And how can I get the Coverity build without errors? Maybe I can configure Coverity to ignore c++ standard headers but I don't now how?
