Cross-compilação Apache portátil Runtime para o iPhone

StackOverflow https://stackoverflow.com/questions/1604470

Pergunta

Esta é uma continuação a uma pergunta anterior sobre compilação cruzada para o iPhone:
bibliotecas baseados em Autotools Cross-compilação para Oficial iPhone SDK

Basicamente, eu estou tentando compilar o portátil Runtime (APR) versão Apache 1.3.8 (última) para o iPhone. Atualmente, estou correndo para o seguinte erro durante a etapa de configuração: 

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.

Eu estou chamando o script "configure" via "iphone3.1-configure --disable-DSO --enable-threads", onde "iphone3.1-configure" é o seguinte script que eu tenho cozido-up para invocar o script "configure": 

#! /bin/bash

#
# Program  : iphone3.1-configure
# Authors  : Michael Aaron Safyan (michaelsafyan@gmail.com)
# Synopsis :
#            This program runs the "configure" script generated by the
#            GNU Autotools in order to cross-compile thirdparty libraries
#            for the iPhone 3.1 SDK. Run this script while in a directory
#            containing an autotools "configure" script. Once you run this,
#            you can use "make" and "sudo make install" to build the library.
#            An install prefix of "/opt/iphone-3.1/" is used.

./configure --prefix="$PREFIX" --build="i386-apple-darwin$BUILD_DARWIN_VER" --host="arm-apple-darwin9" --enable-static --disable-shared ac_cv_file__dev_zero=no ac_cv_func_setpgrp_void=yes $@

O erro que configure está me dando não é a primeira vez que recebi uma mensagem ao longo das linhas de "não pode executar o programa de teste enquanto compilação cruzada". Na verdade, o "ac_cv_file__dev_zero = no" elementos e "ac_cv_func_setpgrp_void = yes" no script "iphone3.1-configure" causam dois testes semelhante deixando de ser contornado. O problema que estou tendo é que eu não sei como contornar este cheque - ou seja, eu não sei o que variável (s) para definir a ignorar este teste e quaisquer análises adicionais que tentam executar arquivos executáveis ??construídos para o alvo plataforma. Eu era capaz de ignorar os dois testes semelhantes anteriores, simplesmente porque eu era capaz de localizar a solução alternativa no Google ... Alguém sabe o que variáveis ??para definir ou outra maneira de contornar essa verificação?

Se alguém sabe uma maneira de suprimir todos os testes que não podem ser executadas quando compilação cruzada, ou se você só sabe como suprimir esta verificação específica, eu ficaria muito grato. Muito obrigado.

Foi útil?

Solução

As seguintes variáveis ??precisam ser definidas:

  • ac_cv_file__dev_zero = "yes"
  • ac_cv_func_setpgrp_void = "yes"
  • apr_cv_process_shared_works = "yes"
  • apr_cv_mutex_robust_shared = "no"
  • apr_cv_tcp_nodelay_with_cork = "yes"
  • ac_cv_sizeof_struct_iovec = "8"
  • apr_cv_mutex_recursive = "yes"

Use a seguinte atualização "iphone3.1-configure" script para configurar o programa: 

#! /bin/bash

./configure \

Use "iphone3.1-configure --disable-dso --enable-threads && make", depois "sudo make install".
