Hi libvirt-list, I run into the same build problem with version libvirt version 0.2.1, 0.2.2 and the latest cvs-version. In libvirt directory I did the following (for cvs version) ./autogen.sh --disable-shared --disable-QEMU I'd like to disable shared libraries and QEMU support (I have only installed xen 3.0.3 envrionment). The make process breaks while building in [/opt/test/libvirt/qemud], while doing the following: <make output> if gcc -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/include/libxml2 -I../ include -I../include -I/usr/include/libxml2 -Wp,-D_FORTIFY_SOURCE=2 - fexceptions -fasynchronous-unwind-tables -Wall -Wmissing-prototypes - Wnested-externs -Wpointer-arith -Wextra -Wshadow -Wcast-align -Wwrite- strings -Waggregate-return -Wstrict-prototypes -Winline -Wredundant- decls -Wno-sign-compare -DLOCAL_STATE_DIR="\"/usr/local/var\"" - DSYSCONF_DIR="\"/usr/local/etc\"" -DQEMUD_PID_FILE="\"/usr/local/var/ run/libvirt_qemud.pid\"" -g -O2 -MT libvirt_qemud-bridge.o -MD -MP - MF ".deps/libvirt_qemud-bridge.Tpo" -c -o libvirt_qemud-bridge.o `test -f 'bridge.c' || echo './'`bridge.c; \ then mv -f ".deps/libvirt_qemud-bridge.Tpo" ".deps/libvirt_qemud- bridge.Po"; else rm -f ".deps/libvirt_qemud-bridge.Tpo"; exit 1; fi bridge.c: In function `brAddBridge': bridge.c:130: error: `SIOCBRADDBR' undeclared (first use in this function) bridge.c:130: error: (Each undeclared identifier is reported only once bridge.c:130: error: for each function it appears in.) bridge.c: In function `brDeleteBridge': bridge.c:148: error: `SIOCBRDELBR' undeclared (first use in this function) bridge.c: In function `brAddInterface': bridge.c:182: error: `SIOCBRADDIF' undeclared (first use in this function) bridge.c: In function `brDeleteInterface': bridge.c:190: error: `SIOCBRDELIF' undeclared (first use in this function) bridge.c: In function `brSetForwardDelay': bridge.c:481: error: `SYSFS_BRIDGE_ATTR' undeclared (first use in this function) bridge.c:481: error: syntax error before string constant bridge.c:481: warning: empty body in an if-statement bridge.c: In function `brGetForwardDelay': bridge.c:503: error: `SYSFS_BRIDGE_ATTR' undeclared (first use in this function) bridge.c:503: error: syntax error before string constant bridge.c:503: warning: empty body in an if-statement bridge.c: In function `brSetEnableSTP': bridge.c:531: error: `SYSFS_BRIDGE_ATTR' undeclared (first use in this function) bridge.c:531: error: syntax error before string constant bridge.c:531: warning: empty body in an if-statement bridge.c: In function `brGetEnableSTP': bridge.c:553: error: `SYSFS_BRIDGE_ATTR' undeclared (first use in this function) bridge.c:553: error: syntax error before string constant bridge.c:553: warning: empty body in an if-statement </make output> I get the same even on the older versions 0.2.2 and 0.2.1. Can you please help me to solve this compilation error? Many thanks in advance, Jan Michael
