c++ - Qt creator cannot find dependent library when running the app -

-

i have qt application project depends on qt library project. have following in application pro file include library.

win32:config(release, debug|release): libs += -l$$pwd/../../commonlibs/build/debug/mylib/release/ -lmylib else:win32:config(debug, debug|release): libs += -l$$pwd/../../commonlibs/build/debug/mylib/debug/ -lmylib else:unix: libs += -l$$pwd/../../commonlibs/build/debug/mylib/ -lmylib  includepath += $$pwd/../../commonlibs/mylib dependpath += $$pwd/../../commonlibs/mylib

until today, application compiled , run, debug application through qtcreator. suddenly, though can compile application, cannot run through qtcreator. when try run it, qtcreator reports application exited if put breakpoint in main(), doesn't hit.

if manually copy dependent library dll file directory application exe exists, can run through qtcreator.

i checked build environment project setting in qtcreator , lib path exists in path variable.

i cannot remember significant action did have created issue.

can give me solution?

the issue library library mentioned in question depends on. have newly created library , made mentioned library depend on it.

to able run application, had add dependency of new library application .pro file. then, worked fine.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
