However, my experiment even doesn't work because of relocation problem in crtbeginS.o My Source file: t.c #include <stdio.h> extern int foo(int argc, char **argv); void *pv1[1024]={(void*)foo,}; char aaaaa[2147483658] = {1, 2 }; char bbbbb[2147483658] = {2, 3 }; void *pv2[1024]={(void*)foo,}; int foo(int argc, char **argv) { printf("%d", aaaaa[2147483657]); printf("%d", bbbbb[2147483657]); return 0; } Command line: gcc -mcmodel=large -fPIC -shared t.c -o t.so Error: /gcc4.5.1/lib/gcc/x86_64-unknown-linux-gnu/4.5.1/crtbeginS.o: In function `__do_global_dtors_aux': crtstuff.c:(.text+0x3): relocation truncated to fit: R_X86_64_PC32 against `.bss' crtstuff.c:(.text+0x37): relocation truncated to fit: R_X86_64_PC32 against `.bss' crtstuff.c:(.text+0x57): relocation truncated to fit: R_X86_64_PC32 against `.bss' crtstuff.c:(.text+0x62): relocation truncated to fit: R_X86_64_PC32 against `.bss' crtstuff.c:(.text+0x6d): relocation truncated to fit: R_X86_64_PC32 against `.bss' Could someone help me figure out the problem? I am using RH5 64bit. My gcc is compiled with all default configuration. Thanks, Wei ^ permalink raw reply [flat|nested] 4+ messages in thread

Can someone add a link to the thread? I have googled for it but this bug report keeps on coming up. I am not too familiar with gcc development so don't know which list is being talked about. I too have a program which requires > 2GB of compiled code on x86-64 and get the errors from "crtstuff.c". But where is it, how do I recompile it? ^ permalink raw reply [flat|nested] 4+ messages in thread
