gtk_entry_set_input_purpose not recognized

Question

I found in the doc the function : gtk_entry_set_input_purpose() to set the input-method of a gtkentry, but when using it, gcc didn't recognize it, it gives me this error

implicit declaration of function ‘gtk_entry_set_input_purpose’ [-Wimplicit-function-declaration]
undefined reference to `gtk_entry_set_input_purpose'

where is the problem?

Answer 1

i think it was a linking problem , compiled successfully with windows after linking all libs ,
