compiling error

I have errors in compiling hickit (make gl=1).

pair.c: In function ‘hk_pair2loop’:

make: *** [hickit] Error 1

After I modified the Makefile, the last error about libglut & libX11 is gone while others still exist. How can these errors be corrected? thanks

Others are warnings, not errors.

this line in th Makefile has been modified as follows

LIBS_GL = -Wl,-Bstatic -Wl,-Bdynamic -lglut -lGLU -lGL -lXi

[zhang-jiankun]

but hickit-gl still doesn't work

[lh3]

Makefile doesn't compile hickit-gl. Only hickit.

Problem solved. Thanks again.
