Questão Como construir e instalar o mais recente SimpleScreenRecorder do git?


Eu quero instalar o SimpleScreenRecorder (SSR) do git como recomendado pelo desenvolvedor. A versão binária falha e é possível que a versão do git já tenha as correções para o meu problema de travamento.

Página principal - SimpleScreenRecorder - Website de Maarten Baert

Infelizmente, não consigo obter a versão git atual / mais recente para construir no Ubuntu. As instruções são encontradas aqui: https://github.com/MaartenBaert/ssr

Nessas instruções, o dev diz: "Se a compilação de 32 bits falhar porque faltam bibliotecas, mas o 64-bit funciona bem, leia as instruções acima novamente :)". Esse parece ser o meu problema, mas ler as instruções novamente não esclareceu meu problema. Então estou perguntando aqui.

Instruções:

sudo apt-get install build-essential pkg-config qt4-qmake libqt4-dev libavformat-dev libavcodec-dev libavutil-dev libswscale-dev libasound2-dev libpulse-dev libgl1-mesa-dev libx11-dev libxext-dev libxfixes-dev g++-multilib ia32-libs

Se a versão de 32 bits de alguma biblioteca não for encontrada, mas o 64-bit funcionar bem, tente o seguinte:

cd /usr/lib/i386-linux-gnu/
sudo ln -s libGL.so.1 mesa/libGL.so
sudo ln -s mesa/libGL.so libGL.so
sudo ln -s libGLU.so.1 libGLU.so
sudo ln -s libX11.so.6 libX11.so
sudo ln -s libXext.so.6 libXext.so
sudo ln -s libXfixes.so.3 libXfixes.so
sudo ldconfig

O dev diz:

Eu não sei se este é o caminho certo para fazê-lo, mas funciona para   mim. Se você estiver usando um driver proprietário, a localização da libGL   ser diferente. Nesse caso, use 'libGL.so' em vez de 'mesa / libGL.so'.   Compilando e Instalando

NOTA: Eu tenho um driver de vídeo proprietário (fglrx). Eu acho que pode ser encontrado aqui (baseado no que eu vejo no xorg.log):

/usr/lib/xorg/modules/drivers/fglrx_drv.so

No entanto, preciso de ajuda específica nesta etapa!

Se você instalou SimpleScreenRecorder como um pacote de um   repositório, você deve desinstalar essa versão primeiro para evitar   conflitos. Se você não fizer isso, as duas versões podem sobrescrever cada   outro ou use a versão errada da biblioteca GLInject.

A maneira mais simples de compilar e instalar tudo é rodar:

./simple-build-and-install

Isto irá compilar o programa principal e biblioteca de 64 bits, e então   Biblioteca de 32 bits. Se a compilação de 32 bits falhar porque as bibliotecas são   faltando, mas 64-bit funciona bem, leia as instruções acima novamente   :)

Esse parece ser o meu principal problema. O erro que vejo é:

configure: error: biblioteca obrigatória ausente

No entanto, também vejo isso:

Detecting ffmpeg/libav ...
Detected ffmpeg.

Isso me preocupa porque o ffmpeg é uma versão compilada customizada e duvido que tenha as opções necessárias ... embora eu tenha ativado a libx264 e talvez isso seja suficiente. Eu não sei. Aqui está a informação relevante do ffmpeg:

Respostas:


Eu tenho esse trabalho com alguma ajuda do desenvolvedor. Primeiro, o dev disse que minha versão do ffmpeg estava boa. Ele também esclareceu que se a saída de simple-build-and-install inclui 'Configurando a biblioteca GLInject de 32 bits' (ou seja, se você conseguir chegar a esse ponto no processo de compilação), isso significa que a parte de compilação de 64 bits está OK. Isso significa que a solução é usar sua solução alternativa de link simbólico.

Abaixo estão os meus passos exatos.

Note que eu pulei um passo recomendado pelo desenvolvedor. Eu pulei porque o link de destino já existia e queria testá-lo sem alterar esse link. (Funcionou.)

sudo apt-get install build-essential pkg-config qt4-qmake libqt4-dev libavformat-dev libavcodec-dev libavutil-dev libswscale-dev libasound2-dev libpulse-dev libgl1-mesa-dev libx11-dev libxext-dev libxfixes-dev g++-multilib ia32-libs
cd /workspaces/ (or any path you choose - see note below)
git clone https://github.com/MaartenBaert/ssr.git (in my case the project path is /workspaces/ssr/)
sudo mkdir /usr/lib32/fglrx/
cd /usr/lib/i386-linux-gnu/
sudo ln -s libGL.so.1 /usr/lib32/fglrx/libGL.so  # only for proprietary AMD drivers!
# SKIP: sudo ln -s fglrx/libGL.so /usr/lib32/libGL.so    # only for proprietary AMD drivers!
sudo ln -s libGLU.so.1 libGLU.so
sudo ln -s libX11.so.6 libX11.so
sudo ln -s libXext.so.6 libXext.so
sudo ln -s libXfixes.so.3 libXfixes.so
sudo ldconfig
cd /path/to/ssr (will be the ssr directory under `/workspaces/` in my example)
$ ./simple-build-and-install 

O resultado final:

Running post-install script ...
Done.

Então eu corri e não caiu! :-) Essa foi a primeira grande mudança.

Então eu testei. Eu usei todas as configurações padrão. E o screencast gravado parecia muito bom !!! Estou extremamente satisfeito. O software é fácil de usar e funciona muito bem.
