It caused by oprofile-0.9.3 is depend on the version of the library it used. I think it is better to add comment of the version gcc, binutils etc that oprofile depend on. thanks. ---------------------------------------------------------------------- Comment By: mao ZhongRu (mzr1) Date: 2008-03-22 11:10 Message: Logged In: YES user_id=2042160 Originator: YES -bash-3.00# find / -name bfd.h ./usr/include/bfd.h -bash-3.00# ldd /usr/local/bin/opreport linux-gate.so.1 => (0xffffe000) libpopt.so.0 => /usr/lib/libpopt.so.0 (0xb7ef5000) libbfd-2.15.94.0.2.2.so => /usr/lib/libbfd-2.15.94.0.2.2.so (0xb7e79000) libdl.so.2 => /lib/libdl.so.2 (0xb7e75000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7da4000) libm.so.6 => /lib/libm.so.6 (0xb7d81000) libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xb7d78000) libc.so.6 => /lib/libc.so.6 (0xb7c5d000) /lib/ld-linux.so.2 (0xb7f02000) So i think the header file bfd.h and bfd library are right.

Like a bfd.h in /usr/local/include but linking is done with /usr/lib/libbfd[...].so ---------------------------------------------------------------------- Comment By: mao ZhongRu (mzr1) Date: 2008-03-21 16:16 Message: Logged In: YES user_id=2042160 Originator: YES -bash-3.00# opreport -l --verbose=all /lib/libc-2.3.4.so /lib/libc-2.3.4.so Archive: Matched sample files: 1 /var/lib/oprofile/samples/current/{root}/a10/bin/rimacli/{dep}/{root}/lib/libc-2.3.4.so/GLOBAL_POWER_EVENTS.100000.1.26298.26298.all profile_classes: event: cpuinfo: CPU: P4 / Xeon with 2 hyper-threads, speed 2992.68 MHz (estimated) class #0: name: GLOBAL_POWER_EVENTS:100000 longname: Counted GLOBAL_POWER_EVENTS events (time during which processor is not stopped) with a unit mask of 0x01 (mandatory) count 100000 ptemplate: event: GLOBAL_POWER_EVENTS count: 100000 unitmask: 1 tgid: 26298 tid: 26298 cpu: all profiles_set #0: image: /a10/bin/rimacli profile_dep_set #0: lib_image: /lib/libc-2.3.4.so profile_sample_files #0: sample_filename: /var/lib/oprofile/samples/current/{root}/a10/bin/rimacli/{dep}/{root}/lib/libc-2.3.4.so/GLOBAL_POWER_EVENTS.100000.1.26298.26298.all callgraph filenames: CPU: P4 / Xeon with 2 hyper-threads, speed 2992.68 MHz (estimated) Counted GLOBAL_POWER_EVENTS events (time during which processor is not stopped) with a unit mask of 0x01 (mandatory) count 100000 op_bfd ctor for /lib/libc-2.3.4.so Segmentation fault -bash-3.00# gdb opreport -l /lib/libc-2.3.4.so Program received signal SIGSEGV, Segmentation fault. 0x080c61f9 in op_bfd (this=0xbfabe7b0, archive=@0x43, fname=@0x43, symbol_filter=@0x43, ok=@0xbfabe70f) at op_bfd.cpp:138 138 if (sect->flags & SEC_CODE) { 133 goto out_fail; 134 } 135 136 // find .text and use it 137 for (sect = ibfd.abfd->sections; sect; sect = sect->next) { 138 if (sect->flags & SEC_CODE) { 139 if (filepos_map[sect->name] != 0) { 140 cerr << "Found section \"" << sect->name 141 << "\" twice for " << get_filename() 142 << endl; ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=116191&aid=1921984&group_id=16191 |
