Compilare Apache Portable Runtime su iPhone

Question

Questo è il seguito di una domanda precedente sulla compilazione incrociata per iPhone:
Librerie basate su autotools cross-compilation per iPhone SDK ufficiale

Fondamentalmente, sto cercando di compilare Apache Portable Runtime (APR) versione 1.3.8 (più recente) per iPhone. Attualmente sto riscontrando il 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 " configura " script tramite " iphone3.1-configure --disable-dso --enable-thread " ;, dove " iphone3.1-configure " è il seguente script che ho preparato per invocare " configura " script:

#! /bin/bash

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

#            containing an autotools "configure" script. Once you run this,

./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 configura mi sta dando non è la prima volta che ricevo un messaggio lungo le righe di "impossibile eseguire il programma di test durante la compilazione incrociata". In effetti, il " ac_cv_file__dev_zero = no " e " ac_cv_func_setpgrp_void = yes " elementi in " iphone3.1-configure " lo script causa il bypass di due test similmente non riusciti. Il problema che sto riscontrando è che non so come bypassare questo controllo - ovvero, non so quale variabile (e) impostare per bypassare questo test e tutti i test aggiuntivi che provano a eseguire eseguibili creati per la destinazione piattaforma. Sono stato in grado di aggirare i precedenti due test simili semplicemente perché sono stato 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 sai semplicemente come sopprimere questo controllo specifico, sarei molto grato. Mille Grazie.

Answer 1

È necessario impostare le seguenti variabili:

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

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

#! /bin/bash

#
# Program  : iphone3.1-configure
# Authors  : Michael Aaron Safyan (michaelsafyan@gmail.com)
# Synopsis :
#            This program runs the "configure" script generated by the

#            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 \

Usa " iphone3.1-configure --disable-dso --enable-thread & amp; & amp; make " ;, quindi " sudo make install " ;.
