Maybe it's the same as: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31490 I have narrowed it down to the following code snippet. But now the complain are for a different parameter. But do not have time to persuade it further. Do you have time to simplify the code snippet and persuade the gcc people? PS. cc: rth as he are in both camps. Sam The following code result in: alpha.c:45: error: __param_resolution causes a section type conflict With gcc: alpha-unknown-linux-gnu-gcc (GCC) 4.2.1 It was build using Dan Kegel's crosstool so I dunno about the exact configure options used. gcc (GCC) 4.1.2 20070502 (Red Hat 4.1.2-12) on x86_64 does not issue this error on the same code snippet. sam-gcc (GCC) 4.2.1 on x86_64 does neither issue same error. sam-gcc I did built myself with: configure --prefix=/home/sam/usr/local --program-prefix=sam- --target=alpha-linux struct kernel_param; typedef int (*param_set_fn)(const char *val, struct kernel_param *kp); typedef int (*param_get_fn)(char *buffer, struct kernel_param *kp); struct kernel_param { const char *name; unsigned int perm; param_set_fn set; param_get_fn get; void *arg; }; extern int param_set_uint(const char *val, struct kernel_param *kp); extern int param_get_uint(char *buffer, struct kernel_param *kp); static const char __mod_author35[] __attribute__((__used__)) __attribute__((section(".modinfo"),unused)) = "author" "=" "Vojtech Pavlik <[EMAIL PROTECTED]>"; static const char __mod_description36[] __attribute__((__used__)) __attribute__((section(".modinfo"),unused)) = "description" "=" "PS/2 mouse driver"; static const char __mod_license37[] __attribute__((__used__)) __attribute__((section(".modinfo"),unused)) = "license" "=" "GPL"; static unsigned int psmouse_max_proto = 1; static int psmouse_set_maxproto(const char *val, struct kernel_param *kp) {}; static int psmouse_get_maxproto(char *buffer, struct kernel_param *kp) {}; static inline unsigned int *__check_proto(void) { return(&(psmouse_max_proto)); }; static int __param_perm_check_proto __attribute__((unused)) = (sizeof(char[1 - 2 * !!((0644) < 0 || (0644) > 0777 || ((0644) & 2))]) - 1); static char __param_str_proto[] = "proto"; static struct kernel_param const __param_proto __attribute__((__used__)) __attribute__ ((unused,__section__ ("__param"),aligned(sizeof(void *)))) = { __param_str_proto, 0644, psmouse_set_maxproto, psmouse_get_maxproto, &psmouse_max_proto }; static const char __mod_prototype45[] __attribute__((__used__)) __attribute__((section(".modinfo"),unused)) = "parmtype" "=" "proto" ":" "proto_abbrev"; static const char __mod_proto46[] __attribute__((__used__)) __attribute__((section(".modinfo"),unused)) = "parm" "=" "proto" ":" "Highest protocol extension to probe (bare, imps, exps, any).
