[WINDOWS] r2frida not working (KNOWN BUG)

[Abdelrahmanamhawy]

Here is the installation process :

Although i didn't use the VC compiler as written in the instructions . When i write r2 in cmd it 's fine and no errors,but when i write "r2 'frida://0'" i get an error saying "ERROR: Cannot open ''frida://0''" Anybody knows how to solve this ? Also, i downloaded the r2frida-5.7.8-w64 from release ,and put the io-frida.dll file in the radare2 's bin folder,but still the error is there . Any help with this ?

Looks like you dont have the radare2\ directory in the source directory. also radare2.exe must be in path, see errors in the output. btw if you can improve the .bat files it will be good.

Use r2 -L | grep frida to check if its loaded or not

you can enable R2_DEBUG=1 env var to get the reason why the plugin is not loaded .

also the io-frida.dll must be copied into the plugins directory not the bin directory.

Okay so i played a little with the build.bat file . I copied the io_frida.dll to the plugins folder for radare2 . Where do i enable r2_debug =1 env var ?

I edited the build.bat file , but still i get this error . I tried "r2 -L" to see if the plugin is in the list but it's not . Any solutions?

I tried to install it on kali linux vm using r2pm ci-r2frida

But i got this log :

Which version of r2 do you have in kali?

[Abdelrahmanamhawy]

radare2 5.0.0 0 @ linux-x86-64 git.5.0.0

[Abdelrahmanamhawy]

Okay so i updated R2 and it now works . But still i get this error : Module version mismatch /home/kali/.local/share/radare2/plugins/io_frida.so (5.7.9) vs (5.0.0) r2pm -ci r2frida [r] Cannot open 'frida://?'

I think that Radare2 and r2frida have different versions,but the problem is that there is no version 5.7.9 for radare2,the last one is 5.7.8 ,i think i will uninstall and download the 5.7.8 version from r2frida .

[trufae]

5.7.9 is the version from git, and its ok to use it. Remove that file and r2pm -ci r2frida should be rebuilding the plugin and the warning may go away
