Question

我已按照此处的指南：debugging pintool guide，但我无法让GDB找到针对我的pintool的调试符号。首先，我使用调试信息编译了我的pintool

lotus@c02-0:~/PerforceArch/home/Shadi/HLS/pin/source/tools/lotusTools$ make DEBUG=1 obj-intel64/dst7.so
g++ -shared -Wl,--hash-style=sysv -Wl,-Bsymbolic -Wl,--version-script=../../../source/include/pin/pintool.ver  -g  -o obj-intel64/dst7.so obj-intel64/dst7.o  -L../../../intel64/lib -L../../../intel64/lib-ext -L../../../intel64/runtime/glibc -L../../../extras/xed-intel64/lib -lpin -lxed -lpindwarf -ldl

在两个不同的终端窗口中，我执行了以下操作：

在第一个窗口中：

lotus@c02-0:~/PerforceArch/home/Shadi/HLS/pin/source/tools/lotusTools$ ~/PerforceArch/home/Shadi/HLS/pin/intel64/bin/pinbin -pause_tool 10 -t obj-intel64/dst7.so -- ls
Pausing for 10 seconds to attach to process with pid 2214
To load the tool's debug info to gdb use:
   add-symbol-file /home/lotus/PerforceArch/home/Shadi/HLS/pin/source/tools/lotusTools/obj-intel64/dst7.so 0x7fa8952e44c0 -s .data 0x7fa895c0f720 -s .bss 0x7fa895c10c40

在第二个窗口中：

问题是在第二个窗口的最后一行，它表示没有找到调试符号。

Answer 1

在我使用调试符号编译之前，我已经编译了调试符号。在使用调试符号重新编译之前，我删除了.so文件，但没有删除.o文件。删除旧的.o文件，然后再打开调试符号，修复问题。

找不到pintool的调试符号
