What do I need to do to link with xlib?

问题

I am using GCC, what switches do I need to add to link with Xlib? After searching, all I could find was -lX11, but that gave me ld: library not found for -lX11

I am using a mac (10.6), but I would not like anything that is Mac specific.

回答1:

You can usually use pkg-config to determine the flags you need to pass:

gcc my-program.c $(pkg-config --cflags --libs x11) -o my-program

回答2:

$ locate libX11
/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib/libX11.6.2.dylib
/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib/libX11.6.dylib
/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib/libX11.a
/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib/libX11.dylib
/Developer/SDKs/MacOSX10.5.sdk/usr/X11/lib/libX11.6.2.0.dylib
/Developer/SDKs/MacOSX10.5.sdk/usr/X11/lib/libX11.6.dylib
/Developer/SDKs/MacOSX10.5.sdk/usr/X11/lib/libX11.dylib
/usr/X11/lib/libX11.6.2.0.dylib
/usr/X11/lib/libX11.6.dylib
/usr/X11/lib/libX11.dylib
/usr/X11/lib/libX11.la

I'd try

gcc [...] -L/usr/X11/lib -lX11 [...]

to set the search path for libraries.

回答3:

You'd be surprised, but sometimes -L/usr/X11R6/lib -lX11 is the answer -_-.

回答4:

You also need -L/usr/X11/lib. It's not exactly Mac-specific, but you will find that the location of these libs will vary a bit from system to system.

回答5:

Ubuntu 12.10 (And probably others) require sudo apt-get install libx11-dev.
