Hi, I am not sure if this has been reported upstream but with libpcap 1.9, user mode linux fails to build. The build failure happens with both, 5.2 and 4.19 LTS kernels.
A much detailed report is available at: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=938962 libpcap 1.9 introduces `pcap_open` which is also declared in linux headers in arch/um/drivers/pcap_user.c Thanks, Ritesh On Sat, 2019-09-07 at 17:18 +0200, Romain Francoise wrote: > Hi, > > On Tue, Sep 3, 2019 at 3:21 PM Ritesh Raj Sarraf <r...@debian.org> > wrote: > [...] > > In file included from /usr/include/pcap.h:43, > > from arch/um/drivers/pcap_user.c:7: > > /usr/include/pcap/pcap.h:835:18: note: previous declaration of > > ‘pcap_open’ was here > > PCAP_API pcap_t *pcap_open(const char *source, int snaplen, int > > flags, > > ^~~~~~~~~ > > make[2]: *** [scripts/Makefile.build:309: > > arch/um/drivers/pcap_user.o] Error 1 > > libpcap 1.9 includes support for remote capture, which was originally > a part of WinPcap extensions.
