From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: I have gcc-3.4.2-6.fc3 and downloaded the Fedora Core 3 dhcp sources from http://download.fedora.redhat.com/pub/fedora/linux/core/3/SRPMS/dhcp-3.0.1-11.src.rpm Now I do rpmbuild --rebuild dhcp-3.0.1-11.src.rpm I get a lot of messages regarding the build process (all fine) until I get: Making all in common make[2]: Entering directory `/usr/src/redhat/BUILD/dhcp-3.0.1/work.linux-2.2/common' cc -g -I/usr/src/redhat/BUILD/dhcp-3.0.1 -I/usr/src/redhat/BUILD/dhcp-3.0.1/includes -DLINUX_MAJOR=2 -DLINUX_MINOR=6 -O2 -g -pipe -m32 -march=i386 -mtune=pentium4 -fpic -c -o raw.o raw.c In file included from raw.c:53: /usr/src/redhat/BUILD/dhcp-3.0.1/includes/dhcpd.h:309: error: mode `byte' applied to inappropriate type /usr/src/redhat/BUILD/dhcp-3.0.1/includes/dhcpd.h:310: error: mode `byte' applied to inappropriate type /usr/src/redhat/BUILD/dhcp-3.0.1/includes/dhcpd.h:311: error: mode `byte' applied to inappropriate type make[2]: *** [raw.o] Error 1 make[2]: Leaving directory `/usr/src/redhat/BUILD/dhcp-3.0.1/work.linux-2.2/common' make[1]: *** [all] Error 1 make[1]: Leaving directory `/usr/src/redhat/BUILD/dhcp-3.0.1/work.linux-2.2' make: *** [all] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.35487 (%build) After searching the internet for what might cause this I found this: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18282 The strange thing is that according to this bug report it should not occur in gcc 3.4.2 (which I have), then again I don't know what patches have been included in the FC3 specific release of gcc-3.4.2. Version-Release number of selected component (if applicable): gcc-3.4.2-6.fc3 How reproducible: Always Steps to Reproduce: As described above. Actual Results: error: mode `byte' applied to inappropriate type Expected Results: No errors. Additional info: I also downloaded the vanilla ftp://ftp.isc.org/isc/dhcp/dhcp-3.0.1.tar.gz and the error message is the same when I try to compile that.
