我已下载PHP 5.4.0源代码，将其解压缩并移至源文件夹中。
我使用以下命令配置：
./configure --build=x86_64-unknown-linux-gnu --host=arm-linux-uclibcgnueabi --prefix=/usr/arm/www CC="arm-linux-uclibcgnueabi-gcc --sysroot=/toolchains/gnu_cortex-a9_tools/" --disable-libxml --disable-dom --without-iconv --without-openssl --disable-simplexml --disable-xml --disable-xmlreader --disable-xmlwriter --without-pear --without-sqlite3 --disable-pdo --without-pdo-sqlite --disable-phar --with-config-file-path=/etc/
其次是
make
没有错误，一切都运行良好。 接下来我做一个make install。
make install
一切都运行良好。 我将它移动到目标平台并运行
/usr/arm/www/bin/php -v
PHP 5.4.0 (cli) (built: Aug 15 2012 16:07:41)
Copyright (c) 1997-2012 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies
我用我的网络服务器和php直接测试一个简单的主页。
<?php echo "hello" ?>
# php index.php
hello
它按预期工作。 接下来我测试：
<?php
$output = shell_exec('ls -lart');
echo "<pre>$output</pre>";
?>
哦，不！〜
# php shell.php
Segmentation fault
我设定了另一个剧本：
#!/bin/php
<?php
echo "hello";
$handle = fopen("info.txt", "r");
echo $handle;
?>
结果相同：
# php index.php
helloSegmentation fault
我有php.ini吗？
# /usr/arm/www/bin/php --ini
Configuration File (php.ini) Path: /etc/
Loaded Configuration File: /etc/php.ini
是的，没有禁用的功能。 测试strace / usr / arm / www / bin / php index.php
lstat("/srv/www/info.txt", {st_mode=S_IFREG|0644, st_size=20, ...}) = 0
open("/srv/www/info.txt", O_RDONLY) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=20, ...}) = 0
lseek(3, 10, SEEK_CUR) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
文件info.txt存在，并且它已经预先读取/写入它。
测试strace / usr / arm / www / bin / php shell.php
fcntl64(3, F_GETFL) = 0 (flags O_RDONLY)
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, 0x7e31fddc) = -1 EINVAL (Invalid argument)
vfork() = 3324
close(4) = 0
fstat(3, {st_mode=S_IFIFO|0600, st_size=0, ...}) = 0
read(3, "total 24\n-rw-rw-r-- 1 1001 "..., 8192) = 468
read(3, ""..., 8192) = 0
--- SIGCHLD (Child exited) @ 0 (0) ---
close(3) = 0
wait4(3324, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 3324
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
如果我通过gdb运行index.php，它会给我：
Starting program: /usr/arm/www/bin/php index.php
hello
Program received signal SIGSEGV, Segmentation fault.
zend_do_fcall_common_helper_SPEC (execute_data=0x2ac7a040) at /home/maiden/Downloads/php-5.4.0/Zend/zend.h:391
391 /home/maiden/Downloads/php-5.4.0/Zend/zend.h: No such file or directory.
in /home/maiden/Downloads/php-5.4.0/Zend/zend.h
gdb从shell.php给我这个 启动程序：/ usr / arm / www / bin / php shell.php
Program received signal SIGSEGV, Segmentation fault.
zend_do_fcall_common_helper_SPEC (execute_data=0x2ab76040) at /home/maiden/Downloads/php-5.4.0/Zend/zend.h:391
391 in /home/maiden/Downloads/php-5.4.0/Zend/zend.h
zend.h位于/ usr / arm / www / include / php / Zend / 显然在交叉编译过程中出了问题。我错过了什么？我没有找到任何配置标志来纠正这一点，并创建一个符号链接到所需的位置删除gdb输出，但PHP仍然是段错误。
感谢您的帮助！

UPDATE2
使用memcheck重新运行valgrind，获得与之前相同的输出，但这是新的：
php: can't resolve symbol '__libc_freeres'
UPDATE3
虽然valgrind让我失望，但我继续使用gdb，我在目标系统上创建了文件夹/home/maiden/..etc并复制了我的php / include文件夹的内容并重新运行gdb。现在我收到此错误消息：
(gdb) run index.php
Starting program: /bin/php index.php
hello
Program received signal SIGSEGV, Segmentation fault.

这与sixeightzero在昨天的评论中所写的非常相似。 我现在尝试了PHP版本5.3.5,5.4.0,5.4.5相同的错误。
