C++ SDL - Pomoc pri inštalácii – C / C++ – Fórum – Programujte.com

Zdravím,chcel by som stiahnuť knižnicu SDL pre C++,v minulosti som to už párkrát skúšal,no neúspešne,pretože vždy mi to vyhadzovalo chyby a celé to prostredie už bolo zle nastavené.Teraz by som to však chcel spraviť hneď na prvýkrát,skúšal som už x návodov aj na YT aj na Googli,avšak väčšina už je starých,taktiež by som chcel vedieť ktorá verzia Visual Studia je "vhodná" (ak na tom vôbec záleží) a či stačí Express alebo plná verzia.Ďakujem :-) 

1. úplně postačí i verze Express, ale pokud nemáš nainstalováno, tak můžu doporučit i Community (na verzi nazáleží).

2. stáhneš toto: https://www.libsdl.org/release/SDL2-devel-2.0.4-VC.zip

3. rozbalíš a nakopíruješ soubory ze složky: 

include do C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include

lib do C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\lib

4. hotovo. (do složky k programu pak vždy přidáš "SDL2.dll", je obsažen ve staženém *.zipu)

Jo a ještě nastavení projektu:

do Linker->Advanced nastavit na main

do Linker->Additional Depencies přidat: SDL2.lib;SDL2main.lib;

Dakujem za radu,rozhodol som sa vyskusat ten VS Community 2015,akurat mam jednu otazku ,pretoze pri instalacii sa ma pyta ,"Aky typ instalacie chcem" ,ci Default alebo Custom,akurat nie som si isty ci Default obsahuje aj C++ .Obrazok s moznostami je po rozliknuti Custom
 

Připojen obrázek.

klidně zvol custom a můžeš pozaškrtávat něco navíc (jestli se ti bude něco hodit). Pokud nic navíc nezaškrtneš, tak se ti nainstaluje vlastně default. Pokud nevíš co zaškrtnout, tak zaškrtni vše co v názvu neobsahuje [3rd Party] (někdy se může hodit mít i po ruce jiné programovací jazyky a nástroje), sice to zabere trochu víc místa na disku a nějaký čas instalace, ale určitě ti nebude nic chybět (pokud ano, můžeš dodatečně něco doinstalovat).

Pro tebe bude asi dobré zaškrknout vše co obsahuje v názvu C++ (kromě 3rd party)

ps, Já vždy pokud něco instaluju tak volím custom, člověk vidí jaké jsou vlastně možnosti.

Nejako som to poskladal,teraz skusam pustit nejake kody,ze ci to vobec funguje,okno mi v pohode vytvorilo,skusam ale uz stlacanie klaves a hadze mi tu nejake chyby ..najskor kod

To vypadá, že to máš projekt starší verze 1.2

https://www.libsdl.org/download-1.2.php

Obě verze můžeš používat současně, jen SDL dej do jiných složek, ale musíš nastavit cesty. Návod máš v tomto odkazu:

http://www.willusher.io/sdl2%20tutorials/2013/08/15/lesson-0-visual-studio/

Aha,dik :-))
