It seems that you only downloaded the library, but not the header files. Depending on the Linux distro you are using, you could download the development header files separately to the binaries/libraries, e.g. on Ubuntu andi@roma:~$ apt-cache search libosip libosip2-3deb - Session Initiation Protocol (SIP) library libosip2-dev - development files for the SIP library Hope that helps, Andi jay wrote: > Hello > I have download libosip2-3.3.0 , but when I to compile sip_reg.c using "gcc > sip_reg.c -o sip_reg -leXosip -L/usr/local/lib -I../../include/ > -DHAVE_STRUCT_TIMEVAL -losipparser2" > ,I got some error msg : > sip_reg.c:55:28: error: eXosip2/eXosip.h: No such file or directory > sip_reg.c: In function 'main': > sip_reg.c:336: error: 'osip_message_t' undeclared (first use in this > function) > sip_reg.c:336: error: (Each undeclared identifier is reported only once > sip_reg.c:336: error: for each function it appears in.) > sip_reg.c:336: error: 'reg' undeclared (first use in this function) > sip_reg.c:366: error: 'eXosip_event_t' undeclared (first use in this > function) > sip_reg.c:366: error: 'event' undeclared (first use in this function) > sip_reg.c:385: error: 'EXOSIP_REGISTRATION_NEW' undeclared (first use in > this function) > sip_reg.c:388: error: 'EXOSIP_REGISTRATION_SUCCESS' undeclared (first use in > this function) > sip_reg.c:391: error: 'EXOSIP_REGISTRATION_FAILURE' undeclared (first use in > this function) > sip_reg.c:394: error: 'EXOSIP_REGISTRATION_TERMINATED' undeclared (first use > in this function) > > > > how can I overcome the problem ? > > cheers, > jay > > >
