C / How to get the width of sfText in pixel?

« on: June 13, 2012, 05:22:55 pm »

Hello,

how can I get the width of a sfText in pixels? In another topic (C++), someone refers to text.GetRect().getWidth(), but there's no sfText_getRect() function in the C binding.

(Edit: I'm using CSFML-2.0-rc)

I'm thankful for any reply.

C / Re: Problems builind an application with sfml2

CSFML depends on SFML, did you install it first?

You're so right! I read over the "c" in libcsfml-graphics.so.2 and thought they're the required libraries. I really didn't notice that I need other ones.   

Thanks for your help.

Hello again,

I also tried to compile my main.c test without IDE (I think it's easier to solve the problem this way, but I still dunno what to do), following this tutorial (just with gcc instead of g++).  My file, main.c, is located in CSFML-2.0-rc, so it's in the same folder as include, lib and share are.

Compile:

$ gcc -c main.c -Iinclude

Build executable:

$ gcc main.o -o sfml-app -Llib -lcsfml-graphics

/usr/bin/ld: warning: libsfml-graphics.so.2, needed by lib/libcsfml-graphics.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libsfml-window.so.2, needed by lib/libcsfml-graphics.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libsfml-system.so.2, needed by lib/libcsfml-graphics.so, not found (try using -rpath or -rpath-link)
lib/libcsfml-graphics.so: undefined reference to `sf::Window::getPosition() const'
lib/libcsfml-graphics.so: undefined reference to `sf::String::toAnsiString(std::locale const&) const'
...

So it's the same result, just without the overhead from the IDE.

The error message tells me to use the -rpath option, but I neither know how to use it nor what exactly the option does. Since the error is not related to runtime (isn't it?), why must I set the "runtime" path?

EDIT: I tried to involve the -rpath option this way:

daniel@daniel-desktop:~/CSFML-2.0-rc$ gcc main.o -o sfml-app -Llib -lcsfml-graphics -Wl,-rpath /home/daniel/CSFML-2.0-rc/lib

But it's still the same error.

Hello,

I think this problem is not related to the library itself, but I'm hoping to get some support here anyway. I got the RC (C-binding) from the download section and copied the folder to my project location. After I included the libraries and include directory to my project properties in Netbeans, it now generates following gcc call to compile the application:

gcc -o dist/Debug/GNU-Linux-x86/netspace build/Debug/GNU-Linux-x86/main.o -Lsfml/lib -Wl,-rpath sfml/lib -lcsfml-audio -lcsfml-graphics -lcsfml-network -lcsfml-system -lcsfml-window

ld's response is this:

/usr/bin/ld: warning: libsfml-graphics.so.2, needed by sfml/lib/libcsfml-graphics.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libsfml-window.so.2, needed by sfml/lib/libcsfml-graphics.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libsfml-system.so.2, needed by sfml/lib/libcsfml-graphics.so, not found (try using -rpath or -rpath-link)

And tons of undefined reference, like

sfml/lib/libcsfml-graphics.so: undefined reference to `sf::Window::getPosition() const'

How to solve this? The -rpath option is set to sfml/lib, the location of all *.so and *.so.2 files (so they're in the -rpath). Why doesn't ld find those libraries?

Thanks for any response
