Dwarf error could not find abbrev number 84

Your code produces multiple warnings.

main.cpp:2:5: warning: declaration of 'int _exit()' conflicts with built-in declaration 'void _exit(int)' [-Wbuiltin-declaration-mismatch]

Even if there is a regressions, the error you see is not fatal (echo $? prints 0) and does not actually cause any problem (as the error message is printed to stderr, not stdout). Earlier versions of bleeding-edge-toolchain (gcc 6, gcc 7, gcc also don’t print this error message, therefore I think the problem is not related to the way the toolchain is built, but most likely to something within binutils.

Edit: Sorry for closing, wrong button.

I have a TCP Client program (TCPClient.cpp) using winsock library. An *.exe is generated successfully if I use command line with the following call:

g++ TCPClient.cpp -o TCPClient.exe -lws2_32

When I try to compile and link the same script within Eclipse/C++ using MinGW I seem to get the *.o file generated but I get an error when generating the *.exe.
Thus, the error is generated if Ecplise/C++ does the following (linker call):

g++ -o TCPClient.exe TCPClient.o -lws2_32 

I get multiple errors:

The following is interesting:
I get the same errors if I use the cmd-line and first generate a .o file and then try to generate a *.exe. Both of the following calls in cmd-line result in the error from above:

g++ TCPClient.o -o TCPClient.exe -lws2_32

g++ TCPClient.o -o TCPClient.exe 

This means: If in cmd-line I only specify that I want to generate (a *.exe from my *.cpp) everything works fine. But — as a user — doing those two steps separately does not work.

Cmd-Line g++ call seems to «know» what to do here. As a user I never see the *.o file when directly generating a *.exe. But I think it must be generated anyway? Am I wrong? Why does cmd-line without further specification know how to deal with the .o file? … Is it possible to find out from any source what a call to «g++» does when called via command line? Of course I want the same settings integrated in eclipse/c++.

У меня проблемы с использованием Boost в автономном приложении .exe.

Я использую IDE CodeBlocks с компилятором minGW и Boost версии 1.67. В параметрах сборки-> каталоги поиска-> компилятор я связал $(#boost) и в Linker $(#boost.lib).

Вот код:

#include <iostream>
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/ini_parser.hpp>

int main()
{
    using boost::property_tree::ptree;
    ptree tree;
    try
    {
        read_ini("C:\Users\M0097932\Desktop\firstTest\torque_trac2_L0.eds", tree);
    std::cout << "test" << std::endl;
    }
    catch(...)
    {
        std::cout << "error" << std::endl;
    }
    for (auto& section : tree) //iterate over tree and print all entries
    {
        std::cout << '[' << section.first << "]n";
        for (auto& key : section.second)
            std::cout << key.first << " = " << key.second.get_value<std::string>() << "n";
    }

    std::cout << std::endl << "Done" << std::endl;
}

Приложение работает нормально, если я запускаю его через IDE (оно печатает все и выходит со статусом 0). Когда я запускаю файл .exe из binDebug, программа падает, и я не получаю никаких исключений («[файл] перестал работать»). Он падает при вызове функции read_ini() (я знаю это, потому что не вижу «тест» в cmd).

Почему приложение вылетает и как это исправить?

Обновлено: Некоторая дополнительная информация по запросу.

Если я запускаю программу .exe через cmd («DataGetter.exe»), при сбое программы ошибка не появляется.

Если я поставлю «g++ DataGetter.exe» в cmd, я получу множество ошибок (но я не уверен, что должен запускать файл .exe таким образом)
