You must be logged in as root to perform a system-wide install. Also note that for a GNOME application to use the pixmaps in the project, it must be installed as a system-wide application. Otherwise, when the application is executed in your project, there will be lots of "pixmap not found" errors. You can configure Anjuta to use sudo or su before installing the project in the build preferences.
Root erabiltzaile gisa sartu behar da, sistema osoko instalazio bat egiteko. Kontuan izan, gainera, GNOMEren aplikazioek, proiektuan pixmap-ak erabili ahal izateko, sistema osoko aplikazio gisa instalatua egon behar dutela. Horrela egin ezean, hainbat "pixmap-a ez da aurkitu" errore izango da proiektuan aplikazioa exekutatzean. Proiektua instalatu aurretik sudo edo su erabiltzeko konfigura dezakezu Anjuta (eraikitze-hobespenetan).
