python - make some modules from global site-packages available in virtualenv -


i want use default (no site packages) of virtualenv.

but modules difficult install in virtualenv (for example gtk). "difficult" mean need have lot of c-header files installed , lot of stuff needs compiled.

i know can solve not installing these packages pip, create symlinks make modules available global site-packages directory.

but right direction?

is there way create symlinks pip or virtualenv?

update

in 2013 wanted modules psycopg2, gtk, python-ldap , other installed on linux server via rpm/dpkg in virtualenv.

the symlinking or other work-arounds did make things more complicated, not simpler. use option today (2017)

--system-site-packages

give virtual environment access global site-packages.

i'd yeah, that's right direction.

your questions sounds similar dealt with: installing opencv virtualenv. problem opencv wasn't available via pip (python package index). ended doing querying system-wide global python installation module in question, , copy-ing .so virtualenv.

the whole process, including boilerplate makefile used, captured here: https://stackoverflow.com/a/19213369/1510289

you similar sym-linking instead of copying. reason ended copying library because use make, , make doesn't handle dependencies symbolic links in way needed (as explained in url above.)

hope helps...

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...
