Cross-compilare Apache Portable Runtime per l'iPhone

Question

Si tratta di un follow-up a una precedente interrogazione sul cross-compilazione per l'iPhone:
Cross-compile Autotools-based Libraries for Official iPhone SDK

In sostanza, sto cercando di compilare l'Apache Portable Runtime (APR) versione 1.3.8 (più recente) per l'iPhone. Sono attualmente in esecuzione nel seguente errore durante la fase di configurazione:

 
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. 

sto invocando lo script "configure" tramite "iphone3.1-configure --disable-DSO --enable-threads", dove "iphone3 .1-configure" è il seguente script che ho cucinato-up per invocare la 'configure script':

 
#! /bin/bash

./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 $@ 

l'errore che configurano mi sta dando non è la prima volta che ho ricevuto un messaggio lungo il le righe di "impossibile eseguire il programma di test durante la compilazione incrociata". In effetti, gli elementi "ac_cv_file__dev_zero = no" e "ac_cv_func_setpgrp_void = yes" nello script "iphone3.1-configure" causano l'esclusione di due test analoghi non funzionanti. Il problema che sto avendo è che non so come bypassare questo controllo - cioè, non so quale variabile (s) impostare per bypassare questo test e qualsiasi test aggiuntivo che tenta di eseguire gli eseguibili creati per il target piattaforma. Sono stato in grado di aggirare i primi due test simili semplicemente perché ero in grado di individuare la soluzione alternativa su Google ... qualcuno sa quali variabili impostare o un altro modo per aggirare questo controllo?

Se qualcuno conosce un modo per sopprimere tutti i test che non possono essere eseguiti durante la compilazione incrociata, o se si sa solo come sopprimere questo controllo specifico, sarei molto grato. Grazie mille.

Answer 1

le seguenti variabili devono essere impostati:

• 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 = "si"
• ac_cv_sizeof_struct_iovec = "8"
• apr_cv_mutex_recursive = "yes"

Utilizza il seguente "iphone3.1-configure" script aggiornato per configurare il programma:

 
#! /bin/bash 

# 
# Program : iphone3.1-configure 
# Authors : Michael Aaron Safyan (michaelsafyan@gmail.com)

#   you can use "make" and "sudo make install" to build the library.

./configure \ 
    --prefix="$PREFIX" \ 
    --build="i386-apple-darwin$BUILD_DARWIN_VER" \ 
    --host="arm-apple-darwin9" \

Usa "iphone3.1-configurare --disable-DSO - -enable-threads & & make ", quindi" sudo make install ".
