I got a problem installing Asterisk

Hi , doing ‘make’ after ‘make menuselect’ i get that trace :
chan_oss.o:/home/experience/Documentos/asterisk-11.15.1/include/asterisk/strings.h:941: primero se definió aquí
collect2: error: ld returned 1 exit status
/home/experience/Documentos/asterisk-11.15.1/Makefile.rules:138: fallo en las instrucciones para el objetivo 'chan_oss.so’
make[1]: *** [chan_oss.so] Error 1
Makefile:387: fallo en las instrucciones para el objetivo 'channels’
make: *** [channels] Error 2

I don’t know what error is . And I dont know how to proceed . Can you help me pls ?

Asterisk 11.15.1 is 3 years old. I’d suggest you try a current supported version instead as the old version may not build on recent versions of Linux.
