c++ - extern "C" with const -

c++ - extern "C" with const -

We have a piece of c-code in our system that includes some of the arrays with Global Access:

source.h

External Contint Magic [5];

source.c:

  const int magic [] = {1, 2, 3, 4, 5}; Someone decided that it would be a good idea to convert it to C ++ and  extern "c"  block: 
 P> Source.h: 
   extract "c" {concrete magic [5]; }  
  source.cc: 
   extern "c" {const int magic [=] {1, 2, 3, 4, 5}; }  
  It is compiled without a thing with GCC-VALIDITY 
  It was not until someone tried to use that array Who has discovered the problem for us. Inside an  extern "c"  inside an  const , no external symbol is generated, it happens with the GCC, Sun Workshop and IBM Compiler. 
  I am about to some degree of damage that it is expected behavior, given that GCC does not warn you that you are doing something strange. 
  Is this behavior to be specified by the standard, or is this a comprehensive bug?

  
  
   const  variable has an internal relationship (as declared  constant ) Unless you use  extern  to specify external linkage if you want to define it in a source file and get it from other people, then you External relation will be required. 
  To specify this language linkage,  extern "C" . 
   Extra "C" {External Contint Magic [5]; }  
  Your announcement is correctly specified external link; But when you turned to C ++, you deleted it.

    Then I have changed cells.js database on mangodeb server with local discount and all my ids have changed to a uuid id . General ID is very easy and cleaner. How can I change my ID again as integer ID?   What are the benefits of using btw UUID?

From the MongoDB site:  "Documents stored in a collection require a unique _id field which acts as the primary key. Since ObjectIds are small, most likely is unique, and Fast to generate "    The primary key and probably some other data are related to them.   If you want to keep the id like 1,2,3,4,5 ... you have to set u...






openstack - How to install packages in cirros OS -



    How to install a package in Cyrus image?   I do not have any installer available in the Siros image that comes with devstack installation.      As @Harik Krishnan commented, cirros does not include a package manager in cirros More useful for the fact that the clouds are working correctly, that VMs are being started properly and things like network, security groups and key pairs are working relatively well.   If you are a package manager Want a Linux VM with, you should see a different distribution . Ubuntu is a good place to start the cloud image -
