调试两例

1.gdb

Program received signal SIG32, Real-time event 32

【转】出现“Program received signal SIG32, Real-time event 32”的解决方法

出现此警告的原因是开发板端/lib下的libthread_db.*(我的是libthread_db.1.0.so）文件不包含debug信息，可在host端使用file命令来查看libthread_db.1.0.so文件是否包debug信息

我的开发板原来的libthread_db.1.0.so使用file命令查看显示为：

libthread_db-1.0.so: ELF 32-bit LSB shared object, ARM, version 1, for GNU/Linux 2.2.5, stripped

handle SIG32 pass noprint nostop

2.valgrind 

# /opt/vg/bin/valgrind  --trace-syscalls=yes ./maintest
