cppcheck / Discussion / General Discussion: Build cppcheck 2.4 on AIX 7.2

There was another build question in 2019 without solution.
Newest build for AIX is from 2014 (v1.63). Thus I want to build it by my own. But I can't get it working.

Environment: AIX 7.2, gcc 8.1, g++, gmake 4.2.1, cmake 3.14
- cmake:

bash-4.4$ mkdir build
bash-4.4$ cd build
bash-4.4$ /opt/freeware/bin/cmake ..

Using g++ directly outputs a hugh error log with messages like not findeing memcpy() and others.

Any hints how to build it on AIX?

Very strange.

Do you get the same output if you run g++ directly?

I'm not a C++ expert. My research leads me to the assumption that TRUE is defined before. I tried something else and this file compiles:

typedef char IfState; #define TRUE 1 #define ELSE_IS_TRUE 2 #define ALWAYS_FALSE 3

  Great find! You found the problem before I did. I will have to adapt simplecpp because it's pretty common that TRUE is defined like that.

But the whole project still doesn't build. This is the whole cmake output:

  Those error: no match for 'operator==' might perhaps be fixed if you use the match compiler;
  
  cmake -DUSE_MATCHCOMPILER=yes ..

    With this flag and the IfState change it looks better now. Still some errors. Output attached.

    I tried to analyze the error:
    lib/standards.h:42:17: error: field 'stdValue' has incomplete type 'std::__cxx11::string' {aka 'std::__cxx 11::basic_string<char>'} std::string stdValue;
    
    I think it must be a configuration problem. A simple program #include <string> and std::string test; compiles without problems. Maybe the Makefile has to do something special on AIX?</string>

      strange!
      standards.h does have a #include <string>.
      do you use some different compiler or compile flags then when you compile your little test program?
      do you get some interesting output when you try this command: g++ -fsyntax-only lib/standards.h.
      have you tried the Makefile in the root folder? what problems do you get with that?

        And my test program:
        
        bash-4.4$ cat test.cpp #include <string> #include <iostream> int main() { std::string test; test = "bla"; std::cout << test << std::endl; return 0; } bash-4.4$ g++ test.cpp -o test bash-4.4$ ./test bla

        I also tried to use -std=c++x9, -std=c++17 and other flags but it didn't help.
        This command doesn't work too:

        Daniel Marjamäki - 2021-06-29
        
        ok I think this command will work better:
        
        g++ -isystem externals -isystem externals/picojson -isystem externals/simplecpp -isystem externals/tinyxml2 -DFILESDIR=\"/usr/share/cppcheck\" -std=c++11 -O2 -DNDEBUG -Wall -Wno-sign-compare -std=c++11 -c lib/analyzerinfo.cpp
        
        Your error output:
        
        In file included from /opt/freeware/lib/gcc/powerpc-ibm-aix7.2.0.0/8/include-fixed/wchar.h:44
        
        I guess that your wchar.h:44 includes a file "standards.h" and the wrong file is included.
        
        Maybe it will be necessary to avoid the -Ilib completely when compiling cppcheck.. if you copy all source files in cli and lib to the same folder that should work. Something like:
        
        python3 tools/matchcompiler.py cp cli/* build/ cp lib/*.h build/ g++ -isystem externals -isystem externals/picojson -isystem externals/simplecpp -isystem externals/tinyxml2 -DFILESDIR=\"/usr/share/cppcheck\" -std=c++11 -O2 -DNDEBUG -Wall -Wno-sign-compare -std=c++11 build/*.cpp externals/tinyxml2/tinyxml2.cpp externals/simplecpp/simplecpp.cpp -o cppcheck

        Thanks for that, Daniel. You're right. The wchar.h includes <standards.h>.
        I copied all files that way and tried again.</standards.h>
        
        At first, the build of analyzerinfo.cpp using your command doesn't have the string error anymore but another one:
        
        In file included from lib/analyzerinfo.cpp:25: externals/tinyxml2/tinyxml2.h:195:1: error: template with C linkage template <class T, int INITIAL_SIZE> ^~~~~~~~ externals/tinyxml2/tinyxml2.h:337:1: error: template with C linkage template< int ITEM_SIZE > ^~~~~~~~ externals/tinyxml2/tinyxml2.h:1896:5: error: template with C linkage template<class NodeType, int PoolElementSize> ^~~~~~~~ externals/tinyxml2/tinyxml2.h:1900:1: error: template with C linkage template<class NodeType, int PoolElementSize> ^~~~~~~~
        
        Using your last g++ command, this error came up multiple times on other files too. The TRUE enum error is there too. I assume this could be fixed easily. But the linkage error is in tinyxml2.h and picojson.h.
        Attached is the whole build log using your last g++ command.

Strange. Could you compress your folder /opt/freeware/lib/gcc/powerpc-ibm-aix7.2.0.0/8.1.0 and provide that?

  I only need the include folders..
