静态链接 log4c-1.2.1 与 Fedora 12 和 Eclipse 3.5.1

Question

我们正在构建一个需要以静态模式链接 log4c 的项目，以下是正在生成的链接器错误的一部分。

/usr/local/lib/liblog4c.a(domnode-expat.o): In function `sd_domnode_read':
/log4c-1.2.1/src/sd/domnode-expat.c:316: undefined reference to `XML_ParserCreate'
/log4c-1.2.1/src/sd/domnode-expat.c:324: undefined reference to `XML_SetCommentHandler'
/log4c-1.2.1/src/sd/domnode-expat.c:325: undefined reference to `XML_SetUserData'
/log4c-1.2.1/src/sd/domnode-expat.c:327: undefined reference to `XML_Parse'
/log4c-1.2.1/src/sd/domnode-expat.c:355: undefined reference to `XML_ParserFree'
/log4c-1.2.1/src/sd/domnode-expat.c:328: undefined reference to `XML_GetErrorCode'
/log4c-1.2.1/src/sd/domnode-expat.c:328: undefined reference to `XML_ErrorString'
/usr/local/lib/liblog4c.a(domnode-expat.o): In function `sd_domnode_fread':

/log4c-1.2.1/src/sd/domnode-expat.c:251: undefined reference to `XML_SetUserData'
/log4c-1.2.1/src/sd/domnode-expat.c:258: undefined reference to `XML_GetBuffer'
/log4c-1.2.1/src/sd/domnode-expat.c:268: undefined reference to `XML_ParseBuffer'

/log4c-1.2.1/src/sd/domnode-expat.c:269: undefined reference to `XML_ErrorString'
collect2: ld returned 1 exit status

乍一看，它似乎缺少 libexpat.a，但 libexpat.a 位于构建机器上，并且 Eclipse 已配置为可以找到它。我们使用 --disable-shared 参数构建了 libexpat.a 到 ./configure，但没有成功。

有什么想法吗？

静态链接问题的解决方案是设置库到其他库的链接顺序

• log4c
• expat
• pthread

这应该允许 log4c 以静态模式链接。
