Hi, Which version of gcc you using? Regards, - AG ----- Original Message ---- From: zhengda <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Sent: Thursday, 5 June, 2008 4:46:12 AM Subject: glibc in Hurd
Hi, I have some troubles with glibc. First, I'm not sure I get the right source code of glibc for Hurd. I download glibc from cvs -d:pserver:[EMAIL PROTECTED]:/cvs/glibc co -r glibc-2_7-branch glibc, and patched it with the patches in http://www.schwinge.homeip.net/~thomas/tmp/glibc-patches/ but I still cannot compile it. I got the error like: /root/storage/glibc_build/rt/librt_pic.a(clock_settime.os): In function `clock_ settime': /root/storage/glibc-2_7-branch/rt/../sysdeps/unix/clock_settime.c:113: undefine d reference to `CPUCLOCK_WHICH' /root/storage/glibc-2_7-branch/rt/../sysdeps/unix/clock_settime.c:113: undefine d reference to `CPUCLOCK_WHICH' Do I use the right patches? So I just simply comment the code as follow: if (CPUCLOCK_WHICH (clock_id) == CLOCK_PROCESS_CPUTIME_ID || CPUCLOCK_WHICH (clock_id) == CLOCK_THREAD_CPUTIME_ID) retval = hp_timing_settime (clock_id, tp); else Now I can compile the source code. My goal is to modify the code of glibc, and to allows the user specify the pfinet server with the environment variable. I modified _hurd_socket_server() and my code is like this: if (domain > max_domain || servers[domain] == MACH_PORT_NULL) { char *sock_serv_path=NULL; int len; char *name=NULL; char *np=NULL; sock_serv_path=getenv("SOCK_SERV_PATH"); if(sock_serv_path == NULL){ sock_serv_path=_SERVERS_SOCKET; } len=strlen(sock_serv_path); name=(char *)malloc(len+100); np=&name[len+100]; *--np = '\0'; np = _itoa (domain, np, 10, 0); *--np = '/'; np -= len; memcpy (np, sock_serv_path , len); printf("socket path: %s\n" , np); server = __file_name_lookup (np, 0, 0); if (domain <= max_domain) servers[domain] = server; free(name); } I want to try the modified glibc. I compile it again, but I don't want to install it in my system directly. I write a very simple test program which only calls socket(). I want to compile the test program with the modified glibc. but I don't know exactly how to do it. What I did is as follow: #gcc -o test test.c # ld -o test glibc_build/csu/crt0.o glibc_build/csu/init-first.o test.o -lc -Lglibc_build but I got the error: /lib/ld.so.1:(.data+0x590): multiple definition of `__hurd_threadvar_stack_offset@@GLIBC_2.2.6' ld: /lib/ld.so.1: indirect symbol `__hurd_threadvar_stack_offset' to `__hurd_threadvar_stack_offset@@GLIBC_2..2.6' is a loop /lib/ld.so.1: could not read symbols: Invalid operation I don't understand why there are multiple definition of __hurd_threadvar_stack_offset? Do I still link to the glibc in my system? Best, Zheng Da Check out the all-new face of Yahoo! India. Go to http://in.yahoo.com/
