python - Emacs & Anaconda. Linking problems -


i have problem where:

  • in order run anaconda, need unset ld_library_path
  • in order run emacs (as other programs), need set ld_library_path

if try run emacs while unsetting ld_library_path run linking problems, e.g. 

symbol lookup error: /usr/lib64/libpangocairo-1.0.so.0: undefined symbol: cairo_ft_font_options_substitute

and run same problem if try load gedit or other programs. given this, unable use anaconda , emacs in same environment.

this prevents me using emacs packages such emacs-jedi (a great package editing , debugging python code) require functioning python environment (specifically emacs-jedi requires epc).

any ideas on how circumvent problem? (note: don't have root access)

update:

  • i have tried prepending $anaconda/lib current ld_library_path, also results in symbol errors described above.

  • i have tried updating $path , $ld_library_path on .emacs file, putting @ top no luck:

    (setenv "path" (concat "/home/josh/installs/conda/1.7.0/bin/:" (getenv "path"))) (setenv "ld_library_path" (concat "/home/josh/installs/conda/1.7.0/lib/:" (getenv "ld_library_path")))

  • here thread explains in more detail errors : linking problems anaconda when using ld_library_path

there several ways fix it, easiest (untested).

(defadvice jedi:start-server (around my-jedi:start-server-ld-library-path-hack                                      activate)   "unset ld_library_path when starting jedi server."   (let ((process-environment (mapcar #'identity process-environment)))     (setenv "ld_library_path")          ; unset $ld_library_path     ad-do-it))

if works, maybe better idea have in jedi.el. can imagine useful change ld_library_path project project.

one of other ways fix run jedi epc server outside of emacs (e.g., in terminal). way, can control environment variables. starter, see: http://tkf.github.io/emacs-jedi/latest/#jedi:toggle-debug-server

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
