[Cppcms-users] undefined reference to `cppcms::widgets::text::size(int)'

[augustin <aug...@ov...>]

Hello,

In the example:
cppcms/examples/forms/
in info_form::info_form(), calling name.size(int n); does not work.
I get the compile error:
 undefined reference to `cppcms::widgets::text::size(int)'

yet the function is defined here:

http://art-blog.no-
ip.info/cppcms_ref_v0_99/classcppcms_1_1widgets_1_1text.html#cdd6d081d3f17291ba374e75cf812e7b
void cppcms::widgets::text::size   (  int   n    ) 
 Set html attribute size of the widget

The following works, however:
name.attributes_string("size='20'")

See the attached patch.

I am not sure if it's a bug in cppcms, or me who does things wrong.


Cheers,

Augustin.

Hello,

Thanks for the report.
Fixed in changeset 1374,
I had added an implementation of the missing function

Hello Arytom,

Thanks for the quick fix. 

However, I did:
 
$ svn update                           
U    src/form.cpp                                                                   
Updated to revision 1375.                      
$ cd build/
$ make
$ sudo make install

As before I added the following line to your form example:
	name.size(20);
The code compiles, now, but the application crashes when I browse it:

cppcms/examples/forms$ ./hello -c config.js
./hello: symbol lookup error: ./hello: undefined symbol: 
_ZN6cppcms7widgets4text4sizeEi


Augustin.

Are you sure you installed this correctly?

Because it seems that hello loads an old shared object instead of new one, 
othewise
you would get a error on linking stage.

Ok. I deleted the whole cppcms build directory, and re-compiled and installed 
everything.
The problem went away.

Thanks for the fix and the help. :)
