gcc ------ 编译与链接选项及CFLAGS、LDFLAGS、LIBS - 流水灯
2020年4月24日 · LDFLAGS告诉链接器从哪里寻找库文件，LIBS告诉链接器要链接哪些库文件。 例子如下： LDFLAGS = -L/var/xxx/lib -L/opt/mysql/lib. LIBS = -lmysqlclient -liconv. LDFLAGS指定-L虽然能让链接器找到库进行链接，但是运行时链接器却找不到这个库，如果要让软件运行时库文件的路径也得到扩展，那么我们需要增加这两个库给"-Wl,R" LDFLAGS = -L/var/xxx/lib -L/opt/mysql/lib -Wl,R/var/xxx/lib -Wl,R/opt/mysql/lib.
Link Options (Using the GNU Compiler Collection (GCC))
On some targets this option also sets flags for the preprocessor, so it should be used consistently for both compilation and linking. -r ¶ Produce a relocatable object as output. This is also known as partial linking. -rdynamic ¶ Pass the flag -export-dynamic to the ELF linker, on targets that support it. This instructs the linker to add all ...

Search the library named library when linking. (The second alternative with the library as a separate argument is only for POSIX compliance and is not recommended.) The -l option is passed directly to the linker by GCC .
target_link_libraries — CMake 3.31.1 Documentation
Specify libraries or flags to use when linking a given target and/or its dependents. Usage requirements from linked library targets will be propagated. Usage requirements of a target's dependencies affect compilation of its own sources. This command has several signatures as detailed in subsections below. All of them have the general form.
