Patch for build gmagick on mac osx 10.6(snow leopard)
在mac osx 10.6.2(snow leopard)编译gmagick失败. 错误如下:
ld: duplicate symbol _php_gmagick_sc_entry in .libs/gmagick_methods.o and .libs/gmagick_helpers.o
collect2: ld returned 1 exit status
make: *** [gmagick.la] Error 1
感觉很奇怪,因为在centos上没问题. 检查了下gmagick_methods.c和gmagic_helpers.c 也没有重复定义啊.
$ nm .libs/gmagick_methods.o |grep _php_gmagick_sc_entry
000000000000f570 S _php_gmagick_sc_entry
$ nm .libs/gmagick_helpers.o |grep _php_gmagick_sc_entry
00000000000034b8 S _php_gmagick_sc_entry
Oh, ld没错, 的确是重复定义了,由于类型是S,那么还是php_gmagick_sc_entry的声明有问题.
再仔细查看了一下,果然. 由于php_gmagick_sc_entry是在php_gmagick.h中声明,而在gmagick_methods.c
和gmagic_helpers.c中都include了这个文件. 由于没有显示声明为exten导致了问题. 重新加入exten修饰符,
ok.

UPDATE: 作者Vito回信很迅速啊, 他只使用Linux,patch已经被采纳了.
解决GraphicsMagick 和 ImageMagick冲突(PHP imagick and gmagick extension)
发现PHP imagick or magickwand无法正确加载. 经过测试发现是由于和gmagick冲突. 解决, 在编译GraphicsMagick时候加入:
–enable-symbol-prefix
重新编译后正常.
