Can I target older linux with newer gcc/clang? C++ -

-

right compile c++ software on old version of linux (sled 10) using provided gcc , can run on newer versions have newer glibc. problem is, old gcc doesn't support c++11 , i'd use new features.

now have ideas, i'm sure others have same need. what's worked you?

ideas:

  1. build on newer system, static link newer glibc. (not possible, right?)
  2. build on newer system, compile , link against older glibc.
  3. build on older system using updated gcc, link against older glibc.
  4. build on newer system, dynamic link newer glibc, set rpath , provide our glibc installer.

as bonus, software support plugins , has sdk. i'd prefer customers compile against libraries without huge hassle.

thanks in advance. ideas welcome, proven solutions preferred.

build newer gcc. either install new compiler on old machine or comile on new machine , install necessary dynamic libraries on old machine.

note multiple versions of libc (and libstdc++) supported on single machine since typically versioned (i.e. libc.so.5, libc.so.6, etc)

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
