Basic string support in Cint

ROOT
1

Hello

Is there any type of string support built into Cint which allows you to easily concatenate strings together such as with the basic_string type ??

Hi,

Just include the string header and you can use std::string:cint.exe> { #include <string> } cint.exe> { std::string s; }

Cheers,
Philippe.

Yes it works after you rebuild the support dll’s.

Hello

Is it possible to add functions to the dictionary which say return a std::string or can you only use the std::string type in a script ??

I seem to be having trouble adding a function to the dictionary which returns a std::string type.

Hi,

Yes, it should be possible. Can you provide a running example showing your issue?

Cheers,
Philippe.

Hello Phillipe

This is what I added to UserMain.h

When I run setupbc.bat I get the following. The problem stems from the fact that it has not included in G__cpp_UserMain.h

Where is G__setup_cpp_environmentXXX() ?? I can’t seem to find it anywhere.

Hi,

You just need to include string directly for UserMain.h :slight_smile:

Cheers,

I did but for some reason it is not picking it up :frowning:

Also my UserMain directory is not in the Cint branch. I am building it somewhere else on the disk. Could that be the problem ??

Do you have a complete running example showing your problem?

Hello Phillipe

I found the problem :wink:

In my UserMain include file I needed to specify “using namespace std” otherwise the std on the std::string doesn’t get carried through when makecint builds the cpp files.

Thanks for your help. It works really well :wink:
