BISON=$(which bison) FLEX=$(which flex) CURL=$(which curl-config) XML=$(which xml2-config) ./configure ________________________________ De : zhihao wang À : xen-devel@lists.xen.org Cc : Ian.Campbell@citrix.com Envoyé le : Jeudi 12 avril 2012 13h12 Objet : [Xen-devel] fatal error if Flex and Bison is not configured Hi all, I try to build xen 4.2( revision number: 25161) on Ubuntu 11.10_amd64, Mac pro. After running ./configure and make. I got the following fatal error: libxlu_cfg_y.y:22:26: fatal error: libxlu_cfg_l.h: No such file or directory compilation terminated. So the original libxlu_cfg_l.h is deleted when making, and should be regenerated but it is not.  I find the path of flex and bison is not set.  When I add the correct path of flex and bison in tools.mk manually, This error is fixed. So, Is there anything in build scripts to modify to avoid this error ?
