The same issue happens to me (amd64 debian testing) without trying parallel build.
I think there is something wrong with the awk script, or maybe even with mawk in debian testing? Generated sip_extra.h starts like that: --------------------------------------------------- /**< SIP, SIPS or TEL URL */ }; typedef struct sip_p_preferred_identity_s sip_p_preferred_identity_t; /**@ingrourl_t paid_url[1]; /**< SIP, SIPS or TEL URL */ }; typedef struct sip_p_preferred_identity_s sip_p_preferred_identity_t; /**@ingrourl_t paid_url[1]; /**< SIP, SIPS or TEL URL */ }; ... --------------------------------------------------- Thanks, Yamato.
