"expected a NativePointer object" #111

Closed bannsec closed 5 years ago

bannsec commented 5 years ago

In playing with r2frida and following the r2con talk about it, i was trying the \dxc command. Unfortunately, it only errors out for me with this error:

[0x00000000]> \dxc main
expected a NativePointer object

[0x00000000]> \dmas "Hello world"
0x7f6ca2357a60

[0x00000000]> \dxc main 0x7f6ca2357a60
expected a NativePointer object

I'm using the pip version of r2rfrida and this r2:

radare2 3.4.0-git 1 @ linux-x86-64 git.3.4.0-git

probably main is not a symbol, try to see what symbols you get with \is and if main is among them, and/or use the address instead of the name if you know it

Even if the symbol name is not there i agree that the error message should be more friendly

Typically this means Module.findExportByName() is used instead of Module.getExportByName().
