Solution to import error of Pbds in windows
By Noob-ita-coder, history, 7 years ago, In English

If any like me get this error while importing the Pbds in #includes..

I got error importing this -> #include<ext/pb_ds/assoc_container.hpp> Error was "cannot open source file hash_standard_resize_policy_imp.hpp ".

Fix go to the dir -> C:\MinGW\lib\gcc\mingw32\8.2.0\include\c++\ext\pb_ds\detail\resize_policy

There u will see a file similar to -> "hash_standard_resize_policy_imp.hpp0000644"

Rename it to hash_standard_resize_policy_imp.hpp

and now it worked for me .

I don't know the real reason why the file was weirdly name before if someone knows plz comment down below and tell.

Hope this helps.

I had been avoiding the hassle of trying to get pbds to work, but it seems like it's this simple! Yay!

Yes it is certainly weird given the fact that they didn't rectified this error for i don't know how long , seems like every version of gcc comes with file like this, or maybe it's not an error at all :|

Probably the most useful post i've read in a while on codeforces!

Thank you, now i don't have to use the custom invocation tab whenever i use pb_ds.

It is not working in windows 10. Is there any other solution for this.

Hey, Can anyone clear my doubt please. If I use my pbds as a mutliset and I want to find the number of elements which are smaller than than any element, is it possible to solve this using pbds?

      I tried it order of key but it gives me the total number of distinct elements less than a element but I want to find the total number of elements smaller than my number. For example, in the pbds with elements 1 2 2 2 4, If I use order of key for element 4, it will give an output of 2 but I want to find a way so that the output would be 4.

        for set:- #define order_set tree<int, null_type,less, rb_tree_tag,tree_order_statistics_node_update>

        for multiset:- #define order_set tree<int, null_type,less_equal, rb_tree_tag,tree_order_statistics_node_update>

        you have to use less_equal instead of less in syntax to make it work as a multiset. order_of_key will give correct in the second case
