Como instalar SDL no Gcc???

[Natureba]

Ae pessoal...
Desculpe a pergunta um tanto NB, mas eu queria saber como eu instalo a biblioteca SDL no gcc para compilar o jogo CUBE...
Eu procurei em alguns lugares, mas as informações estiveram sempre muito confusas e nao consegui o que eu queria... via apt-get achei uns programas tipo libsdl1.2-algumacoisa, soh que eu nao sabia se eu deveria baixar ou qual deveria baixar...

Alguem pode me ajudar???

OBS: Eu quero compilar o jogo Cube a fins de estudar a biblioteca SDL e a linguagem C, modificando seu conteudo e vendo os resultados, portanto dispenso ajudas como: "baixe o jogo ja compilado" , pois nao é isso que quero... o jogo compilado eu ja tenho....

Valeu...
Abraços... xD

Vc já usa o GCC p/ alguma coisa?

Se não, tenta baixar o pacote build-essential... Talvez funcione. Acho que um dos maiores micos do Ubuntu é não vir com esse pacote por padrão; apesar de ser uma distribuição completamente voltada ao usuário comum, é tradição as distros de Linux virem com o GCC já utilizável, sem precisar de mais nada.

Aliás q, bibilioteca SDL é essa? Nunca ouvi falar 

Espero ter ajudado

apt-get install libsdl1.2-dev

esse é meu garoto

bom eu dei o apt-get install libsdl1.2-dev e instalou tudo certinho.... mas quando eu vou compilar o jogo com o comando:

e isso por que ainda nao couberam todos os erros no terminal e todos que couberam no terminal nao foram permitidos pelo forum devido ao tamanho da mensagem...
o que estou fazendo de errado??? será que é o comando???
alguem sabe o que pode ser???

Valeu.
Falou.

[mientefuego]

tenta baixar o build-essential, sério...

talvez funcione.

[daskrs]

Abre o makefile do Source do Cube e copia aqui pra a gente ver quais libs ele usa.

[AlexBR]

Você mostrou apenas a parte final do log de erros. Deixou o mais importante, ou seja, o início, de fora. Antes desse ponto, deve aparecer o primeiro erro, o que causou todos os outros. Normalmente, é a falta de um arquivo cabeçalho *.h. Você deve ver qual é esse cabeçalho e procurar em qual pacote está o cabeçalho faltoso. Depois, é só instalar o pacote e tentar novamente.

Boa sorte!

[Natureba]

ao instalar build-essential o apt-get fala que ja possuo a versão mais nova...

[AlexBR]

Cara, sem ver o início dos erros, vai ser complicado resolver o seu problema.

Você manda compilar, quando chegar no ponto que você perceber que já está dando erro, vc tecla ctrl+C.

[Darcamo]

Esses erros que vc exibiu são apenas consequências e não a causa do problema. A causa certamente é algum arquivo de cabeçalho que ou não foi incluído ou não foi encontrado. Erros desse tipo aparecem no começo e causam várias outras mensagens de erro depois. Por isso precisamos ver o início dos erros como o AlexBR mencionou.

De qualquer forma, além do libsdl1.2-dev você também precisa dos pacotes libsdl-image1.2-dev e libsdl-mixer1.2-dev

Talvez também precise dos pacotes libsdl-net1.2-dev, libsdl-sound1.2-dev, libsdl-ttf1.2-dev ou libsdl-ttf2.0-dev.

[Natureba]

Ok... mas o único meio de pegar o começo dos erros mesmo é mandar o terminal salvar o log dos erros em um arquivo, pois os erros aparecem muito rapido e nao da tempo de um ctrl+c ...
eu nao lembro o comando para o terminal salvar a saída de um comando em um arquivo txt... alguem sabe como eu faço???
acho que era alguma coisa a ver com a inclusão de um "> log.txt" no comando, mas nao tenho certeza...

Abraços.

[e.daniel-ct]

pelo q eu entendi ai a bibilhoteca sdl ainda nao esta instalada, falo isso pq tive o mesmo problema aki so q eu peguei essa bibilhoteca no tar.gz e compilei, nao lembro nem o jogo q eu tava tentando instala mais sei q depois de muito tenta cabei desistindo, se vc consgui resolve o problema eu também agradeço valeu

[Darcamo]

A SDL tem nos repositórios. Então é muito mais fácil instalar por eles do que compilar.
Quanto a jogar os erros no arquivo de texto acho que é só colocar depois do comando
>> log.txt

[e.daniel-ct]

É mais aki estamos falando da lib sdl q como vc pode ver é indicado entre os erros a falta de funções q tem exatamente o nome iniciando com essa lib pra ser mais exato a ki eu compilei foi a SDL-1.2.11.tar.gz, blz
