Problems with PC-LINT and gcc 4.8 / STL (on Ubuntu)
For the project, we switched the project from Windows to Linux, and while PC-LINT works fine with wine, I can't get PC-LINT to work with a simple test program. PC-LINT always complains about STL headers. I went through all the Gimpel documentation about gcc and I am using co-gcc.h and I created lint_cppmac.h, size-options.lnt and gcc-include-path.lnt. We are using PC-LINT version 9.00k and I tried with 9.00k4 as well. gcc is version 4.8.2 on Ubuntu 14.04 LTS.
So here's what I am doing:
lint-nt.sh -voip +b std.lnt /home/test/test.cpp
lint-nt.sh is just a helper script for running PC-LINT under Linux with wine and for converting the output (i.e. backslashes to slashes) and contains the following:
#!/bin/bash
DIR=`dirname $0`
# Options that are passed to PC-Lint before any other options.
# -fff: Under Linux, filenames are case-sensitive.
# +rw(__is_pod): __is_pod is a GCC toolchain-specific keyword.
PREOPTS="-fff +rw(__is_pod)"
wine ${DIR}/LINT-NT.EXE $PREOPTS "$@" | tr '\\\r' '/ '
test.cpp contains the following:
#include <iostream>
class Base {
public:
Base(int i) : m_i(i), m_pi(new int[i]) { }
~Base() {}
int get() { std::cout << m_i << std::endl; return m_i; }
private:
int m_i;
int *m_pi;
};
std.lnt just contains the following (default files from gimpel)
co-gcc.lnt // gcc compiler options
lib-stl.lnt // STL
So when I run I get these errors (snippet)
/home/test/test.cpp 11 Info 783: Line does not end with new-line

I tried to use std namespace and without it. I tried test files with help <string>
and it got worse.
I appreciate every hint to get this job done . Thank you in advance
