/usr/bin/ld:编译-ldb时找不到iproute2

Question

我试图在Fedora 19上编译iucute2-3-12-0，我已经安装了BerkeleyDB，ls -la /usr/lib/libdb*命令给出了以下结果：

-rwxr-xr-x 1 root root 1847852 May 16  2013 /usr/lib/libdb-5.3.so
lrwxrwxrwx 1 root root      12 Sep 18 20:15 /usr/lib/libdb-5.so -> libdb-5.3.so
lrwxrwxrwx 1 root root      18 Jan  4 12:57 /usr/lib/libdbus-1.so.3 -> libdbus-1.so.3.7.4
-rwxr-xr-x 1 root root  317720 Nov 11 19:24 /usr/lib/libdbus-1.so.3.7.4

我有最新版本的Bison和Flex。我使用内核: 3.12.8-200.fc19.x86_64。我在/usr/lib and /usr/lib64有ldb。不过，我没有在LDFLAGS中找到任何Makefile。

我收到一个错误：

ssfilter.y: conflicts: 27 shift/reduce
/usr/bin/ld: cannot find -ldb
collect2: error: ld returned 1 exit status
make[1]: *** [arpd] Error 1
make: *** [all] Error 2

仔细看一看make日志的末尾就会发现：

我怎样才能让ld找到libdb？

Answer 1

lib将包含32位库和lib64 64位。我假设您的gcc正在生成64位二进制文件。因此，/lib64 (/usr/lib64)需要有正确的数据库库。您可以使用--verbose手动运行gcc命令，查看它所做的一切。(即它正在运行的ld命令)
