Hello, We have decided to migrate from Solaris to Linux one year ago. Our systems are based on AMD Opteron and it was decided that our Linux distribution (Debian Sarge was chosen) had to be 32bit, except our homebrew applications, which have to be 64bit. That's why we have a 64 bit GCC installation somewhere on our NFS that was tuned to use by default /usr/lib64 instead of /usr/lib, and other workarounds like that. This was done by a kind of Linux guru, who isn't with us anymore. So the knowledge was lost... (Very professional, isn't it?) For my project I need g77 (especially libg2c) in order to use the AMD flavour of LAPACK (ACML). It wasn't included in our installation, that's why I'm trying to compile GCC 4.0.2. I redefined CC in order to refer our custom GCC and tried to launch 'configure' like this: ./configure --prefix=/some/where/ --with-cpu=opteron --with-march=opteron The result is (obviously) an error... /tmp/ccHtARnb.s: Assembler messages: /tmp/ccHtARnb.s:37: Error: `completed.4353(%rip)' is not a valid 32 bit base/index expression /tmp/ccHtARnb.s:38: Error: suffix or operands invalid for `push' /tmp/ccHtARnb.s:39: Error: suffix or operands invalid for `movq' /tmp/ccHtARnb.s:45: Error: `p.4352(%rip)' is not a valid 32 bit base/index expression /tmp/ccHtARnb.s:48: Error: `p.4352(%rip)' is not a valid 32 bit base/index expression /tmp/ccHtARnb.s:49: Error: `(%rax)' is not a valid 32 bit base/index expression /tmp/ccHtARnb.s:58: Error: `completed.4353(%rip)' is not a valid 32 bit base/index expression /tmp/ccHtARnb.s:72: Error: suffix or operands invalid for `push' /tmp/ccHtARnb.s:75: Error: suffix or operands invalid for `movq' /tmp/ccHtARnb.s:81: Error: `__JCR_LIST__(%rip)' is not a valid 32 bit base/index expression /tmp/ccHtARnb.s:87: Error: bad register name `%r11' /tmp/ccHtARnb.s:89: Error: bad register name `%r11' Not really surprising, according that the assembly code is certainly 64bit. As far as I know, my binutils are in 32bit and without any option 'as' and 'ld' will assume that they have to deal with 32bit code. I tried to override LDFLAGS with '-m elf_x86_64' (before configure, like CC), but there isn't any ASFLAGS... Does anyone have an idea? Should I make something like a cross-compilation? Any help will be welcomed...
