It should follow the same convention as the system directories. For instance, if I use CPATH=/home/vlefevre/include then it should add: /home/vlefevre/include/x86_64-linux-gnu /home/vlefevre/include for x86_64 compilation, and /home/vlefevre/include/i386-linux-gnu /home/vlefevre/include for i386 compilation (i.e. with -m32). -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
