Drawing UTF-8 string extracted from variable/xml with sf::Text

[bokoblin]

Hello,

I'm trying for some time to draw french text with sf::Text.
This works using setString(L"français");
But it obviously can't work with text contained in variable/parsed from elsewhere
because you can't do
string test = "français";
setString(Ltest); or setString(L\"test\"); or setString(test); (the latter returns strange characters)

I just tried using sf::String but while the official tuto says I can draw this because it is inherited from sf::Drawable, my compiler says that sf::String is not compatible with class sf::Drawable.

So what can I do to draw UTF-8 parsed text ?


I'm on Windows 10 with SFML 2.3.2 on CLion IDE

std::string utf8_string = <extracted from file>;

sf::Text text;
text.setString(sf::String::fromUtf8(utf8_string.begin(), utf8_string.end()));

Merci, ça fonctionne, je commençais à désespérer de trouver une solution !

[Laurent]

In english please

I know, but it was because you are french ^^

Anyway, It works great on Windows, but when I try compiling my project on linux I have the following error :

In member function ‘virtual void Button::sync(DataBase*)’:
158:27: error: ‘fromUtf8’ is not a member of ‘sf::String’
m_label.setString(sf::String::fromUtf8(utf8_string.begin(), utf8_string.end()));
make[2]: *** [CMakeFiles/runner.dir/src/view/Button.cpp.o]
Erreur 1
make[1]: *** [CMakeFiles/runner.dir/all] Erreur 2
make: *** [all] Erreur 2

I'm using SFML 2.3.2, located in <project directory>/libs/SFML-2.3.2

You must include a old header, sf::String::fromUtf8 was added in SFML 2.2.

[bokoblin]

What do you mean by including an old header ? I tried
#include <SFML/System/String.hpp> because it is in this header where fromUtf8 is, but it doesn't work

[Laurent]

What I say is that the version of <SFML/System/String.hpp> that gets included in your code (which is often not the one we expect) is older than SFML 2.2. Make sure that your version is up-to-date, and that you don't have other older versions of SFML installed elsewhere.

[bokoblin]

I had indeed an old version on my system. I understood "you must" as what I should do

[bokoblin]

Cmake is working by replacing :
FIND_PACKAGE(SFML 2 COMPONENTS system window graphics audio REQUIRED )
by
FIND_PACKAGE(SFML 2.3 COMPONENTS system window graphics audio REQUIRED )

but "make" have undefined references for sf::color and sf::renderstate only

here is attached the command that make executes for linking into an executable

The order of the libraries to link is wrong.

FIND_PACKAGE(SFML 2.3 COMPONENTS audio graphics window system REQUIRED )

[bokoblin]

Hello, thanks but same issue with your proposition :/ I did thought about it this afternoon (and had forgotten it just after, though)

[eXpl0it3r]

Make sure you do clean CMake's cache and run CMake again.

[bokoblin]

Yes it's what I do each time by deleting build folder, just checked again and it fails at "linking CXX executable"

[eXpl0it3r]

So what's the exact error message?
