error: pathspec 'r2-5.3.1' did not match any file(s) known to git

[APIPLM]

Following the steps:

1. yum install radare2
2. r2pm -i rlang-python

error: pathspec 'r2-5.3.1' did not match any file(s) known to git

Then cd ./radare2/r2pm/git/radare2-rlang , then ./configure

Using PKGCONFIG: /usr/bin/pkg-config
checking pkg-config flags for r_core... no
This package is required

I am on Centos 7

This is a warning you can ignore. Its just trying to fetch a commit that works for such an old version of r2. But as long as there’s no issue it just pulls master.

the second error is because you dont have:

• pkgconfig installed
• The development package of radare2

I would suggest you to install r2 from git or ping the maintainer to get it updated to .5.5.4

[APIPLM]

Thanks. It should update to the latest version of radareorg/radare2. There are two compilation errors during compiling radareorg/radare2-rlang/python with version 5.3.1. But on my site, clone https:// take for a while or even get blocked. The installation scripts in repo radareorg/radare2 mostly have to clone its dependencies project from the github , then it can go forward.

And also in the archive repo , in both CensOS 7 and CensOS 8 Linux platform , the only available version is 5.3.1, is there any place to download the version 5.5.4 of radare2-devel? Or I have to git clone the version 5.5.4 of radareorg/radare2 to build because the radareorg/radare2-rlang dependence on the the radare2-devel 5.5.4?

i have been digging around to fix checking pkg-config flags for r_core... no
any idea how to ? for someone not that experience in deep solving codes and strange tools
i never used pkg-config tool before
i just need to fix that to be able to proceed learning binary exploits

[APIPLM]

I have not investigated this yet. But as I talked with people about pkg-config, It is a standard tool in some of Lunix distribution like freedesktop.org

One more thing I found out is the pkg-config tool like Work with the meta infomation of building the installed package,which is the *.pc file.

i fixed it by sudo apt-get install libxxhash-dev
