Is it possible to merge the fix to the version provided via pip? test version is working fine, but if you install from pip on macos, it still fails

thanks for the library and mutli OS support

Ok, I've merged the necessary changes into the "test" branch. I've also added a patch that re-enables Net-SNMP 5.6.2.1 support on macOS. You can choose to use the Brew Net-SNMP or system-included Net-SNMP library. (If you need modern SSL cipher support, go with Brew).

Unfortunately, the project looks like it has been abandoned. I wonder if there are any alternatives (other than the abandoned PySNMP)?

Looks like you're experiencing an issue with library resolution due to how the old method of extracting info from brew was being performed.

Please try the following and report back on whether or not it installs correctly:

pip install https://github.com/easysnmp/easysnmp/archive/testing.zip

I have net-snmp installed without using homebrew.

That's correct; sorry for the bad URL.

Brew is certainly installed. The keg Net-SNMP does not appear to be.

> snmpbulkwalk --version

NET-SNMP version: 5.6.2.1

Are you using the system-included Net-SNMP binaries/library? If so, we highly recommend using the Homebrew package instead as this will include some memory leak fixes and newer OpenSSL support. brew update && brew install net-snmp is all you'd need to run before trying to install EasySNMP again.

If you cannot install Net-SNMP via brew for some reason (security restrictions, explicit Net-SNMP library version required, etc), please let us know why.

Ah ok, I missed an important detail from your output after installing Net-SNMP via Brew.

error: /Library/Developer/CommandLineTools/usr/bin/otool-classic: can't open file: build/lib.macosx-10.9-universal2-3.10/easysnmp/interface.cpython-310-darwin.so (No such file or directory)

I'm able to replicate this on my 12.5 VM. I'll dive into it.

kamakazikamikaze avatar kamakazikamikaze commented on June 4, 2024

Looks like the issue is due to pip running the egg_info command and the setup.py script performing a library link regardless of what command is passed in. I'll probably need to look into extending the build_ext/build commands so that this step only occurs when the C extension is built. Hopefully I can have it patched by Monday.

Now the installation (from test) runs correctly. Thank you very much!
