I'm new to the world of bui开发者_Python百科lding. I've always let my IDE take care of it for me, but now I'm working with autotools and command line.
Could someone explain the difference between gcc's
-l LIBNAME - Search for library LIBNAME
and
-L DIRECTORY - Add DIRECTORY to library search path
Can the same linking be accomplished with either and it's just a style preference which gets used? Or is there actually something seriously different happening?
Thanks,
Andrew
Usually you use both:
- -l libname specifies the libraries you want to link, think single files.
- -L specifies paths where the linker should look for them (in addition to the standard ones), think directories
The -L command adds a path to the list of locations the linker searches to find libraries.
The -l option means it searches for a library by the name you specify
Basically the -l option tells it to look for a library by that name and -L allows you to specify places to look.
