Dear gcc-help team, thank you very much for your support! After installation of glibc with the missing stubs-32.h, gcc built successfully, apparently allowing both -m32 and -m64. One suggestion though: When i'm installing software, i'm used to read README, but here it just said that "The directory INSTALL contains copies of the installation information as HTML and plain text." (which is not true!), and also points to gcc/doc/install.texi, but i don't know what to do with a .texi-file (my lack of experience, i know...). INSTALL/README is the next thing that i would read, but it mainly tells me "This directory has been obsoleted for GCC snapshots and CVS access." I would find it helpful to find the full installation instruction as plain text in README or INSTALL/README or something called INSTALL.txt, together with a link to http://gcc.gnu.org/install/ Yours sincerely Simon
