Compiling under windows

[q8ing]

Hello,

When I tried to compile it under windows, I got the following error:

C:>cd r2dec-js

C:\r2dec-js>make -C p The system cannot find the path specified. The system cannot find the path specified. The system cannot find the path specified. The system cannot find the path specified. The system cannot find the path specified. The system cannot find the path specified. make: Entering directory C:/r2dec-js/p' 'rm' is not recognized as an internal or external command, operable program or batch file. 'sleep' is not recognized as an internal or external command, operable program or batch file. make: *** [clean] Error 1 make: Leaving directoryC:/r2dec-js/p'

Any solution, please?

[wargio]

oh, please use meson under windows or a unix shell like cygwin or msys2 to build.

[Maijin]

Maybe update this @wargio - https://github.com/wargio/r2dec-js#windows-users-only

[wargio]

yes, you are right. i'd like to have a confirmation from @q8ing

[q8ing]

Thank you for your replay. At the beginning I thought I could compile It using make on windows OS, because the instructions didn't mention anything about meson. I tried meson, but I got the following error:

I don't know how to modify include path, because windows doesn't allow me to create a directory with (. ) as a name.

[wargio]

the . directory is the same directory.

[xarkes]

I think there's a mistake with the include directory. I don't know where/how it's introduced, but you could try to copy it in your bin folder.

[q8ing]

Yeah, I copied it to the directory and It solved the problem, But I got another problem, I think it is related to the compiler. I am using the latest version of mingw32 gcc compiler. Any help is appreciated.

I used the 64 bit version of Mingw and I have compiled it successfully. I tried pdd? But it is not decompiling the file.

Any help is appreciated.

You have to move the pdd .dll file inside your radare2 plugins folder.

[pelijah]

And set R2DEC_HOME env variable or copy whole r2dec-js dir to %R2_RDATAHOME%\r2pm\git\ where %R2_RDATAHOME% is path returned by radare2.exe -H R2_RDATAHOME.

[q8ing]

Thank you guys for helping me. I did everything you told me. I used "radare2 -H" to get plugins directory path and after I moved .dll and .lib files to plugins directory, I got this error when i ran radare2

I have no idea how to solve it.

[pelijah]

You can upload an image right here.

[xarkes]

I think you should not copy the lib, only the dll.

[q8ing]

I think you should not copy the lib, only the dll.

I had already done that before and radare2 crashed when I used "pdd" plugin. Here is an image to show you what I mean:

@q8ing Can you paste the output of radare2 -v and radare2 -V ?

So do you want to use 32-bit dll with 64-bit app?

[q8ing]

So do you want to use 32-bit dll with 64-bit app?

How can I build r2dec-js for 64 bit version? could you help me, please?

[pelijah]

Maybe MinGW64? You can also get core_pdd.dll from a Cutter dist https://github.com/radareorg/cutter/releases (goto radare2\lib\plugins\ subdir).

I had already compiled it using Mingw64 version. I tried "core_pdd.dll" from Cutter and it worked without any problems.

I have no idea why the compiled version is not working!!!

Thank you for your help.

[pelijah]

Well, sorry, I didn't notice your comments about MinGW64 and working pdd? command. In fine, r2 loads and initializes r2dec plugin, but plugin crashes when you call pdd. So you can try to debug it.

[q8ing]

I'll close this issue and I wish the developers will solve the problem related to .dll. Also, It would be better If the instructions for compiling under Windows are updated.

Thank you very much guys.

[wargio]

fixed instructions on how to build it on windows. thanks for the issue :)

[q8ing]

You are always welcome my friend :)))
