I don't know what happens when there are two version of gcc in your system.
"apt-get install g++ 4.2.4 " doesn't mean to install g++-4.2.4. Instead, it means install two different software: "g++" and "4.2.4". I think if you can find a up-to-date Ubuntu source server with latest version of gcc, the apt will upgrade it for you automatically, so you don't need to remove the old version. eng Rony wrote: > > > > > Eng Rony > > i check the version of g++ in my system, by g++ -v, and i found it gcc > version 4.1.3 > now i will install g++ 4.2.4 by sudo apt-get install g++ 4.2.4 > i have 2 questions:- > 1- do i must remove my old version "gcc 4.1.3"? > 2- if i keep my old version how can i make g++ 4.2.4 my default? > thanks > > > > --- On Sat, 10/11/08, Wang Danqi <[EMAIL PROTECTED]> wrote: > From: Wang Danqi <[EMAIL PROTECTED]> > Subject: Re: [ns] errors when type make > To: ns-users@ISI.EDU > Date: Saturday, October 11, 2008, 6:15 AM > > > It seems your compiler considers the declaration of "char** p_info::name_ > char*" is different from the definition of "p_info::name_ > [59]". > > You may check the version of g++ in your system, by g++ -v > > g++ 4.2.4 works well with ns-allinone-2.33 > > > eng Rony wrote: >> >> >> >> >> Eng Rony >> >> [EMAIL PROTECTED]:~/ns-allinone-2.33/ns-2.33$ make >> >> g++ -c -Wall -DTCP_DELAY_BIND_ALL -DNO_TK -DTCLCL_CLASSINSTVAR -DNDEBUG >> -DL= >> INUX_TCP_HEADER -DUSE_SHM -DHAVE_LIBTCLCL -DHAVE_TCLCL_H >> -DHAVE_LIBOTCL1_13= >> -DHAVE_OTCL_H -DHAVE_LIBTK8_4 -DHAVE_TK_H -DHAVE_LIBTCL8_4 -DHAVE_TCL_H >> -D= >> HAVE_CONFIG_H -DNS_DIFFUSION -DSMAC_NO_SYNC -DCPP_NAMESPACE=3Dstd >> -DUSE_SIN= >> GLE_ADDRESS_SPACE -Drng_test -I. -I. >> -I/home/rania/ns-allinone-2.33/tclcl-1= >> ...19 -I/home/rania/ns-allinone-2.33/otcl >> -I/home/rania/ns-allinone-2.33/inc= >> lude -I/home/rania/ns-allinone-2.33/include -I/usr/include/pcap -I./tcp >> -I.= >> /sctp -I./common -I./link -I./queue -I./adc -I./apps -I./mac -I./mobile >> -I.= >> /trace -I./routing -I./tools -I./classifier -I./mcast >> -I./diffusion3/lib/ma= >> in -I./diffusion3/lib -I./diffusion3/lib/nr -I./diffusion3/ns >> -I./diffusion= >> 3/filter_core -I./asim/ -I./qs -I./diffserv -I./satellite -I./wpan -o >> commo= >> n/packet.o common/packet.cc >> common/packet.cc:44: error: conflicting declaration 'char** > p_info::name_' >> common/packet.h:277: error: 'p_info::name_' has a previous > declaration as >> '= >> char* p_info::name_ [59]' >> common/packet.cc:44: error: declaration of 'char* p_info::name_ > [59]' >> outsi= >> de of class is not definition >> common/packet.cc:45: error: 'unsigned int p_info::nPkt_' is not a > static >> me= >> mber of 'class p_info' >> >> =20 >> common/packet.cc:46: error: expected constructor, destructor, or type >> conve= >> rsion before '*' token >> common/packet.cc:48: error: no 'int p_info::addPacket(char*)' > member >> functi= >> on declared in class 'p_info' >> common/packet.cc: In member function 'int > p_info::addPacket(char*)': >> common/packet.cc:50: error: 'nPkt_' was not declared in this scope >> common/packet.cc:51: error: 'initName' was not declared in this > scope >> common/packet.cc:53: error: 'nPkt_' was not declared in this scope >> common/packet.cc:55: error: 'initName' was not declared in this > scope >> make: *** [common/packet.o] Error 1 >> [EMAIL PROTECTED]:~/ns-allinone-2.33/ns-2.33$ >> >> >> >> >> >> >> > > -- > View this message in context: > http://www.nabble.com/errors-when-type-make-tp19886080p19894159.html > Sent from the ns-users mailing list archive at Nabble.com. > > > > > > > > -- View this message in context: http://www.nabble.com/errors-when-type-make-tp19886080p19938906.html Sent from the ns-users mailing list archive at Nabble.com.
