postgresql - Deployment issues of Psycopg2 Python App -


i have created application in python tested , runs on computer (mac osx 10.8.3 python2.7.3 postgresql9.2.4 psycopg2-2.5). app compiled using py2app, , can see build included packages/modules application contents folder.

psycopg2 imports correctly on machine, , app runs fine, when application runs on computer (i've tried 4 different computers...), fails open, , console message reads importerror: dlopen(/applications/app.app/contents/resources/lib/python2.7/psycopg2/_psycopg.so, 2): library not loaded: libpq.5.dylib

i have searched , modified code extensively through s.o. , google no avail. psycopg2 links not address issue. http://initd.org/psycopg/articles/2010/11/11/links-about-building-psycopg-mac-os-x/

i have removed , reinstalled psycopg2 & postgresql numerous times, building source, macports, homebrew, etc. current environment listed above, postgresql 9.2.4 installed homebrew, , psycopg2-2.5 installed source while explicitly linking pg_config location in setup.cfg

when run otool -l on _psycopg.so, following

/usr/lib/libpq.5.dylib (compatibility version 5.0.0, current version 5.4.0) /usr/lib/libssl.0.9.8.dylib (compatibility version 0.9.8, current version 47.0.0) /usr/lib/libcrypto.0.9.8.dylib (compatibility version 0.9.8, current version 47.0.0) /usr/lib/libsystem.b.dylib (compatibility version 1.0.0, current version 169.3.0)

how can built application include (or point target user files if available) these files? correct approach? py2app of course not include system files /usr/lib/ in "frameworks" option.

your copy of _psycopg.so linked system installation of libpq, not libpq home-brew build of postgresql 9.2.4.

because of application work on systems running osx 10.8.

the solution rebuild psycopg2 , make sure linked home-brew build of postgresql.

note py2app not copy files /usr/lib application bundles, when explicitly told include shared library, because assumes files in /usr system files , redistributing @ best dodgy w.r.t. licenses.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
