我正在尝试自己编译PHP,因为我想使用PHPBrew在多个版本的PHP之间切换.
我已经在这个过程中解决了很多问题,但是对于这个问题,我无法进一步解决.我在make过程中收到此错误消息：
/usr/bin/ld: /usr/libpcre.a(pcre_exec.o): relocation R_X86_64_32S against `_pcre_ucd_stage1' can not be used when making a shared object; recompile with -fPIC
/usr/libpcre.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
make: *** [libPHP5.5.5.la] Fehler 1
Error
我需要从/usr/libpcre.a添加一个符号链接 – > /usr/lib/x86_64-linux-gnu/libpcre.a之前,否则他会抱怨找不到libpcre.a.
我还尝试添加“EXTRACFLAGS = -fPIC”来制作,但它不会改变任何东西.这是我第一次编译某些东西,所以我甚至不确定我是否掌握了正确的基础知识.
这是在Ubuntu 13.10下(在12.04没有看到相同的问题).这是我的PHPBrew命令：
PHPbrew install 5.5.5 +default+MysqL+pdo+apxs2
这将导致生成以下配置选项：
./configure ‘–prefix=/home/malte/.PHPbrew/PHP/PHP-5.5.5’
‘–with-config-file-path=/home/malte/.PHPbrew/PHP/PHP-5.5.5/etc’

/home/malte/.PHPbrew/build/PHP-5.5.5/build.log
我想我已经安装了所有相关的软件包：
dpkg --get-selections | grep pcre
libpcre++0:amd64 install
libpcre3:amd64 install
libpcre3:i386 install
libpcre3-dev:amd64 install
libpcrecpp0:amd64 install
任何帮助真的很感激！
解决方法:
您需要使用与位置无关的代码重建libpcre.直接的方法是构建或安装使用-fPIC构建的libpcre共享对象(例如libpcre.so).
由于库存档位于/usr/lib / x86_64-linux-gnu中,因此共享对象也可能存在.尝试将-L /usr/lib / x86_64-linux-gnu添加到PHP的LDFLAGS.这也将使您免于符号链接到/ usr.
