c++ - Using defined value in include -

-

i have #include file structures following:

#include <core/mod1/file1.hpp> #include <core/mod1/file2.hpp> #include <core/mod1/mod2/.../modn/filen.hpp>

and there such includes in each file. example, in file core/mod1/file1.hpp there might #include <core/mod3/file5.hpp>. here core name of library. want use core_new instead of core in entire project, without modifying files (actually lot). have tried add #define core core_new, hoping kind of substitute need:

#define core core_new #include <core/mod1/file1.hpp> #include <core/mod1/file2.hpp> #include <core/mod1/mod2/.../modn/filen.hpp>

but not it: core/mod1/file1.hpp being included instead of core_new/mod1/file1.hpp. there way achieve it?

you want use file system, not c++ compiler. make new directory , copy/link source files on there. change -i option in compiler to use new directory. of course, have new files in the new core directory. way don't need edit single source/header file.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
