linux - libcvd - undefined reference to "x..." while compiling c++ -


i trying build libcvd in order use ros (from www.ros.org). problem getting following errors:

make[3]: entering directory `/opt/ros/groovy/stacks/tum_ardrone/thirdparty/libcvd/build' /usr/bin/g++-4.6 -o progs/cvd_display_image progs/cvd_display_image.o -l. -lcvd  -ltiff -ljpeg -lpng -lpng -llapack -lglu -lgl -lrt  -l -lx11 -lxext -pthread  ./libcvd.so: undefined reference `xmovewindow' ./libcvd.so: undefined reference `xcreateglyphcursor' ./libcvd.so: undefined reference `xstorename' ./libcvd.so: undefined reference `xlookupstring' ./libcvd.so: undefined reference `xfreefont' ./libcvd.so: undefined reference `xsetclasshint' ./libcvd.so: undefined reference `xcreatewindow' ./libcvd.so: undefined reference `xcreatecolormap' ./libcvd.so: undefined reference `xopendisplay' ./libcvd.so: undefined reference `xdestroywindow' ./libcvd.so: undefined reference `xclosedisplay' ./libcvd.so: undefined reference `xunmapwindow' ./libcvd.so: undefined reference `xnextevent' ./libcvd.so: undefined reference `xsetwmprotocols' ./libcvd.so: undefined reference `xresizewindow' ./libcvd.so: undefined reference `xmapwindow' ./libcvd.so: undefined reference `xselectinput' ./libcvd.so: undefined reference `xflush' ./libcvd.so: undefined reference `xwarppointer' ./libcvd.so: undefined reference `xloadqueryfont' ./libcvd.so: undefined reference `xdefinecursor' ./libcvd.so: undefined reference `xinternatom' ./libcvd.so: undefined reference `xquerypointer' ./libcvd.so: undefined reference `xundefinecursor' ./libcvd.so: undefined reference `xgetwindowattributes' ./libcvd.so: undefined reference `xpending' collect2: ld returned 1 exit status make[3]: *** [progs/cvd_display_image] error 1 make[3]: leaving directory `/opt/ros/groovy/stacks/tum_ardrone/thirdparty/libcvd/build' make[2]: *** [libcvd_built] error 2

there other stackoverflow question similar errors (undefined reference error while compiling libcvd).

i tried suggested there find out why there no path given second -l option. ended in projects configure.in file, believe error happens. have no experience build system, great.

the configure.in file available under https://dl.dropboxusercontent.com/u/16804463/configure.in

thanks in advance.

the chosen solution in other question not right. right solution 1 that's not chosen: error have missing path in link line. link line contains: -l -lx11. there should pathname after -l. since there isn't, linker assumes pathname next argument, -lx11. means linker doesn't link actual libx11.so library because it's treating library reference path instead.

you need @ makefile , find rule link cvd_display_image.o target, , see going on here. mentioned in other answer, you'll find link line -l$(some_variable) , variable empty. need set variable value, perhaps running make some_variable=. or make some_variable=/usr/lib or whatever.

seeing configure.in file not useful: important part makefile.

in event should report maintainers of software can fix it: have real error here multiple people running it.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
