Bibliotecas baseados em Autotools cross-compilação para Oficial iPhone SDK

Eu estou escrevendo um programa que tem como alvo vários telefones diferentes, incluindo o iPhone. O programa depende de várias bibliotecas de terceiros. Estou tendo dificuldade-cross compilação destas de terceiros bibliotecas para o simulador de iPhone e iPhone. As bibliotecas incluem o tempo de execução Apache portátil e GNUTLS, bem como suas dependências. Eu gostaria que as bibliotecas construídas para acabar no prefixos "/opt/iphone-3.1", "/opt/iphone-3.0", "/opt/iphone-2.2.1", "/opt/iphone-simulator-3.1 ", e "/opt/iphone-simulator-3.0", respectivamente.
A fim de tornar o processo de cross-compilação facilmente reproduzível, eu estou criando scripts para chamar o script "configure" para cada uma das plataformas de destino ( "iphone3.1-configure", "iphone3.0-configure", " iphone2.2.1-configure", "iphonesim3.1-configure", e "iphonesim3.0-configure"). Aqui é onde eu estou tendo problemas.
Eu estou usando um Mac OS X 10.6 computador Snow Leopard com o Xcode 3.2 oficial + iPhone SDK 3.1.

Actualmente tenho o seguinte "iphone3.1-configure" script:

Na pasta "apr-1.3.8", eu estou correndo "iphone3.1-configure --disable-dso", e estou recebendo:

Pergunta ??h2>
Como faço para corrigir o "iphone3.1-configure" script? Obrigado.
Solução
Ok. Isto ainda não construir, mas torna-se muito mais ...
- O pré-processador C não pode tomar uma arquitetura.
- O pré-processador C não aceita --sysroot ou -isystem (é só usar '-i').
- Use "CPP" em vez de "CPP-4.2" (a versão 4.2 estiver com defeito, e uma vez que é o pré-processador, não importa qual versão você usa, de qualquer maneira, então você pode muito bem usar o que funciona .)
A versão atualizada do script iphone3.1-configurar é:

Além disso, eu estou chamando com "--enable-threads --disable-DSO", não apenas "--disable-dso". Isso ainda não funciona ... ele está falhando com:
checking for PTHREAD_PROCESS_SHARED in pthread.h... yes checking for pthread_mutexattr_setpshared... yes checking for working PROCESS_SHARED locks... configure: error: in `/Users/michaelsafyan/Downloads/apr-1.3.8': configure: error: cannot run test program while cross compiling See `config.log' for more details.
No entanto, este pode ser um problema com testes específicos de APR. Estou postando um acompanhamento questão à ligação.

Eu tenho desde uma solução mais completa em Cross-compilar o Apache Portable Runtime para o iPhone .
Outras dicas
Obrigado por seu script. Ele me ajudou muito. Embora eu tive que fazer algumas alterações para que a arquitetura do meu lib construído é arm
e não i386
.
Em primeiro lugar, eu tive que mudar o compilador:
# export CC="$DEVROOT/usr/bin/gcc-4.2"
export CC="$DEVROOT/usr/bin/arm-apple-darwin10-gcc-4.2.1"
Então eu removi a opção -arch armv6
, pois isso compilador não entendê-lo, de CFLAGS, CXXFLAGS, LDFLAGS
Atualizado a versão SDKVER e gcc e funcionou!
