Hi, I've the same problem here on Gentoo Linux. gcc version 4.4.4 (Gentoo 4.4.4-r2 p1.2, pie-0.4.5) flex 2.5.35
Fresh chckout: ./autogen.sh ./configure make ... cc1: warnings being treated as errors text_import_scanner.c: In function ‘text_importlex’: text_import_scanner.l:97: error: ignoring return value of ‘fwrite’, declared with attribute warn_unused_result text_import_scanner.c: In function ‘yy_get_next_buffer’: text_import_scanner.c:1121: error: comparison between signed and unsigned integer expressions make[2]: *** [text_import_scanner.o] Error 1 make[2]: *** Waiting for unfinished jobs.... mv -f .deps/wsp_stat.Tpo .deps/wsp_stat.Po make[2]: Leaving directory `/home/gergap/work/wireshark/gtk' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/gergap/work/wireshark' make: *** [all] Error 2 Then I copied the configure line from buildbot where it works. ./configure --prefix=/home/<user>/tmp/wireshark --enable-extra-gcc-checks make and it works. I also think it's this "treat warning as errors" setting. The option --enable-extra-gcc-checks seems to set it correct. Maybe this info helps you.
