Interesting, the error does not see ln at a glance related to the MATLAB version. Can you provide more info on:

• Distro/os version used
• PKG manager used to install dependencies (if conda, report also conda list)
• anything that may be strange in your setup

[EhsanRanjbari]

• Distro/os version used

Ubuntu 22.04.3 LTS.

• PKG manager used to install dependencies (if conda, report also conda list)

apt (followed https://github.com/robotology/robotology-superbuild?tab=readme-ov-file#source-installation)

• anything that may be strange in your setup

only this error: https://github.com/robotology/yarp/issues/2885#issuecomment-1876782445

The issue https://github.com/robotology/yarp/issues/2885#issuecomment-1876782445 seems to be resolved. But still getting the BlockFactory error mentioned in the first comment.

Interesting, there is indeed a bug, but I do not know how nobody ever noticed this. Can you provide the build/src/blockfactory/CMakeCache.txt file? Perhaps are you using a compiler different from the standard one provided in Ubuntu 22.04?

[traversaro]

@EhsanRanjbari can you test if https://github.com/robotology/blockfactory/pull/72 fixes your problem?

[EhsanRanjbari]

Here is build/src/blockfactory/CMakeCache.txt: CMakeCache.txt.

And #72 fixed the problem. Thanks. I will close the issue shortly.

[traversaro]

Perfect, I releases 0.8.4 with this fix: https://github.com/robotology/blockfactory/releases/tag/v0.8.4 .
