Linux за българи: Форуми

Искам да инсталирам това нещо, но срещам необясними за мен засега спънки.
Това е адреса, от който се сваля нещото:

https://github.com/enkore/j4-dmenu-desktop

Там е описано, как се инсталира, но при мен нещо не се получава. Инсталирах cmake, gcc-4.8, направих каквото е казано:

cmake .
make

и до тук.

Има няколко неща, които не са ми ясни. Какво е git и как работи. Инсталирах и това, но доколкото разбрах, това е просто начин за работа в екип. Или греша? Трябва ли нещо да изпълня на моята машина, за да мога да инсталирам едно просто приложение? Това е изхода от make:

jerry# make

До този момент не ми се е налагало да компилирам нещо особено. Най-много нещо дребнично и старичко, което го няма в хранилищата и всичко си е минавало както трябва. Но тук няма ./configure , а cmake, което предполагам прави същото. Гледах изхода от make, но незнаейки основни неща и как се случва всичко, не мога да схвана, какво не наред.

Проблемът е C++11 компилаторът ти не поддържа всички нови записи т.е. вероятно поддържа частично С++11.

GeSHi (C++):
constexpr uint32_t operator "" _istr(const char *s, size_t)
{
    return make_istring(s);
}

Application.hh 35 ред коментирай 4-те реда

GeSHi (C++):
case "Name"_istr:

става

GeSHi (C++):
case make_istring("Name"):

111 ред по нататък:

GeSHi (C++):
case "Exec"_istr:

->

GeSHi (C++):
case make_istring("Exec"):

видиш _istr го махни и го замени с make_istring, което е функция и трябва стринга да го предаваш като параметър. После в Main.hh 191

GeSHi (C++):
Dmenu *dmenu = 0;   int parsed_files = 0;   char *buf = 0;  size_t bufsz = 4096;

ги премести в конструктора

GeSHi (C++):
Main()

инициализациите т.е. долу в 191 ред остава само

GeSHi (C++):
Dmenu *dmenu;

в Main()

GeSHi (C++):
dmenu = 0;

и за останалите така. Разбираш ли С++? Ако ти е трудно това трябва да си намериш gcc 4.8.0 минимум, за да компилираш.

Преди доста време се опитвах да правя нещо на c++. Синтаксиса мисля, че няма да ме обърка. По-скоро непознаването на функциите. Ще пиша какви съм ги натворил.  ::)
