PHP擴展不能在Mac OS上編譯10.6

我試圖在Mac OS 10.6上編譯一個名爲xtree的PHP擴展，但卻遇到了關於丟失符號的幾個錯誤。我已經能夠在運行Debian 4的機器上成功編譯它，而不會丟失符號錯誤。PHP擴展不能在Mac OS上編譯10.6

生成文件顯示爲：

LIBTOOL = /usr/bin/libtool 
INSTALL = /usr/bin/install 

PHPINC := $(shell /opt/local/bin/php-config --includes) 
PHPLIBS := $(shell /opt/local/bin/php-config --libs) 
PHPDEST := $(shell /opt/local/bin/php-config --extension-dir) 

XTREE_LIB = xtree2.so 
OBJS = xtree.lo tree.lo node.lo parser.lo string.lo token.lo xsock.lo xpath.lo buffer.lo 

.SUFFIXES : .lo .c 

all : ${XTREE_LIB} 

clean : 
    rm -f *.o 
    rm -f *.lo 
    rm -f *.so 

.c.lo : 
    gcc -fpic -DHAVE_XTREE -DPIC -DCOMPILE_DL_XTREE ${PHPINC} -c -o [email protected] $< 

${XTREE_LIB} : ${OBJS} 
    gcc -shared -L/usr/local/lib -rdynamic -o ${XTREE_LIB} ${OBJS} 

install : ${XTREE_LIB} 
    $(INSTALL) -c ${XTREE_LIB} ${PHPDEST}/${XTREE_LIB}

下面是在Mac上編譯時我收到了錯誤的樣品。

Undefined symbols: 
    "__php_stream_open_wrapper_ex", referenced from: 
     _tree_load_xdf in tree.lo 
     _tree_save_xdf in tree.lo 
     _tree_cache_control in tree.lo

PHP安裝在本地主機和php-配置正確運行指向了包括庫，擴展-dir的正確位置等

談起我的一些同事，他們建議鏈接器不能動態地正確指向庫。但是，他並不熟悉Mac OS鏈接器以瞭解如何解決此問題。

任何想法？

UPDATE

我也有以下建議我，但沒有運氣之一：

Anyways, here's a few random things you could try: 

- In the linker line of the Makefile (starts with "gcc -shared"), add 
the "-dynamiclib" parameter after "gcc". You may also need to remove 
the "-shared" and/or "-rdynamic" parameters. 

- In the linker line, add "-bundle -flat_namespace -undefined 
suppress". Again, you may need to dump "-shared" and/or "-rdynamic".

仍尋求幫助。謝謝！

做'/選擇/ local/bin目錄/ PHP的配置--libs'與他人合作？另外，我希望'$（PHPLIBS）'可以用在某個地方。 – Wodin 2010-12-20 09:21:58

是的，/ opt/local/bin/php-config --libs和其他工作。 – janiv 2010-12-20 22:42:16

嘗試改變：

${XTREE_LIB} : ${OBJS} 
    gcc -shared -L/usr/local/lib -rdynamic -o ${XTREE_LIB} ${OBJS}

這樣：

${XTREE_LIB} : ${OBJS} 
    gcc -shared -L/usr/local/lib -rdynamic -o ${XTREE_LIB} ${OBJS} $(PHPLIBS)
