还好我们有gdb,下面就 通过4步搞定php c extension的调试。 if test -z "$PHP_DEBUG"; then AC_ARG_ENABLE(debug, [ --enable-debug compile with debugging symbols ],[ PHP_DEBUG=$enableval ],[ PHP_DEBUG=no ]) fi ./configure –enable-debug --enable-yourmodule//和调试c程序的-g是一样的效...
In the symbol file (vmlinux, an elf file), the symbols before __primary_switched are all mapped at virtual addresses (starting with 0xffffffc0... high addresses) but the gdb could follow the source even when the PC value was using physical address. (The PC was initially loaded with ph...
