我想将/opt/vertica/lib64添加到系统库路径中，因此我执行以下步骤:
(1)将/opt/vertica/lib64添加到/etc/ld.so.conf中，然后运行ldconfig，
(2)检查:
bash# ldconfig -p | grep vertica
libverticaodbc.so (libc6,x86-64) => /opt/vertica/lib64/libverticaodbc.so
......
但是当我运行“
ld -lverticaodbc --verbose”命令时:==================================================
attempt to open /usr/x86_64-redhat-linux/lib64/libverticaodbc.so failed
attempt to open /usr/x86_64-redhat-linux/lib64/libverticaodbc.a failed

ld: cannot find -lverticaodbc
ld从verticaodbc中找不到/opt/vertica/lib64。有人可以提供一些线索吗？非常感谢!
最佳答案
ld是静态linker。 ld.so是dynamic linker(而ldconfig和ldd与动态链接器相关)。
您需要在链接时将-L/opt/vertica/lib64/添加到ld参数中(通常应与gcc或g++链接)。实际上，这意味着编辑构建基础架构-例如您的Makefile-添加几十个字符。
参见ld.so(8)，ldd(1)，ld(1)，ldconfig(8)
