Unable to install with r2pm - Ubuntu 20.04

[br0kej]

I have been trying to install r2retdec using r2pm and it is currently failing with the following error.

> r2pm -i r2retdec

Install Done For r2retdec
make: *** No rule to make target 'install'.  Stop.

From digging into ~/.local/share/radare2/r2pm/git/r2retdec and executing make - I get the following error:

My google foo suggests its something to do with git references/submodules but am unsure.

r2retdec is not really working on linux nowadays, it somehoe works on mac just because how the runtime linker works. but retdec needs to update their capstone and fix their linkage. but still your error seems unrelated to this and yes the packet seems to pick an unexistent commit hash. you can try building it from git by hand instead of r2pm.

The r2retdec is referencing this commit which seems to be removed from the (thirdparty) retdec repository

deps/retdec/CMakeLists.txt: GIT_TAG 73184b0c17b8790ab691217d2ab4cb6d569495fb

Can you try updating it and make a PR with a working one?

I've just got round to investigating this further and seems to have run into a road block. I haven't been able to get the it to work having played around with several different git commits on Ubuntu 20.04.

I have managed to kinda' get it to work on Mac OS but am running into an odd issue when the CMake build just randomly bugs out with an error 2 - Problem for another day I think.

Want me to close this issue or leave open in case someone else is able to fix?

[trufae]

Uh? After the last release of retdec that should work. Is the problem you are having in retdec or in r2retdec?

I only tested it on macos and it works as expected

[trufae]

Keep the issue open. I will try to find some time in a week or so to check this out
