mongodb @4.4.1_0 mongod: cannot execute binary file on macOS 10.15

[ValeryKV]

I have upgraded macOS to 10.15 and installed Xcode 12.2, then I followed "Migration procedure" and reinstalled all ports. After that mongod failed to start. I uninstalled mongodb and reinstalled it again, but it did not help. Most possible it was built as 32 bit. Here are some outputs:

api:~ valery$ mongo
-bash: /opt/local/bin/mongo: cannot execute binary file

api:~ valery$ file /opt/local/bin/mongo
/opt/local/bin/mongo: data

api:~ valery$ ls -al /opt/local/bin/mongo*
-rwxr-xr-x  1 macports  admin  51098720 Nov 14 22:45 /opt/local/bin/mongo
-rwxr-xr-x  1 macports  admin  85955312 Nov 14 22:45 /opt/local/bin/mongod

Replying to ValeryKV:

Most possible it was built as 32 bit.

That should be impossible, since the port was built on Catalina and it is not possible to build 32-bit software on Catalina.

[ryandesign (Ryan Carsten Schmidt)]

And if it were 32-bit, running file on it would have said that it was a 32-bit Mach-O file, but it said it was "data", which means file couldn't identify what it was, which is strange.

Make sure that you have installed both Xcode 12.2 and the Xcode 12.2 version of the command line tools.

Try rebuilding mongodb one more time, this time using the -k flag to tell MacPorts to keep the work directory and log:

sudo port clean mongodb
sudo port -nsk upgrade --force mongodb

Assuming the mongo program still doesn't work after that rebuild, please show us the build log.

The log file will be at the location printed by the command:

port logfile mongodb

Compress this file and attach it to the ticket so that we can see what happened.

Also, maybe show us the first few bytes of the mongo file by running:

$ hexdump -n 128 /opt/local/bin/mongo

Here is what that looks like on the file that was built by our Catalina buildbot worker:

I installed Command Line Tools for Xcode 12, not 12.2, because they tell the version 12.2 is pre-release software.

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 12.0.0.0.1.1599194153
volume: /

Must I use the Xcode 12.2 version of the command line tools?

If version 12.0 is OK, I will try to rebuild with -k flag.

[ryandesign (Ryan Carsten Schmidt)]

You should always use a matched set of Xcode and the Xcode command line tools. Xcode 12.2 is not prerelease software anymore. The final version of both Xcode 12.2 and the Xcode 12.2 version of the command line tools were released on November 12. Doesn't matter what versions you use, as long as they're compatible with your OS and are a matched set.

Don't know why your files start with zeroes like that, but that's definitely unusable, so get a matched set of Xcode and CLT and then rebuild mongodb per my previous instructions and show us the log if it builds wrong again.

logfile

[ValeryKV]

I installed the command line tools for Xcode 12.2.

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
version: 12.2.0.0.1.1604628099

Then I rebuilt mongodb

$ sudo port clean mongodb
$ sudo port -nsk upgrade --force mongodb
$ /opt/local/bin/mongo
-bash: /opt/local/bin/mongo: cannot execute binary file
$ file /opt/local/bin/mongo
/opt/local/bin/mongo: data

The log file is attached to the ticket.

[ryandesign (Ryan Carsten Schmidt)]

So far I don't see anything unusual in your log to explain this.

Do you see this problem only with mongodb or also with files installed by other ports?

Is your disk ok? Try running First Aid in Disk Utility.

[ValeryKV]

Php, python, perl, nginx and other ports work great. I will try First Aid later. After that I installed mongo via brew to /usr/local/opt/mongodb-community@4.0/bin/mongod . It works. I may try to reinstall mongodb v4.0. What command to run?

[ryandesign (Ryan Carsten Schmidt)]

We only offer one version of mongodb in MacPorts—the one in the mongodb port.

If you're adventurous you can try installing an older version of the port.

[ryandesign (Ryan Carsten Schmidt)]

Note that having software installed with Homebrew can interfere with MacPorts being able to build software properly, and vice versa. If you had software installed with Homebrew when you built mongodb, that could have caused the problem, and you might try building again after removing Homebrew. See wiki:FAQ#usrlocal.

[ValeryKV]

I never used Homebrew before. I needed working version of mongodb. After MacPort version failed for me, I installed mongodb 4.0 with Homebrew. The last try I rebuilt mongodb with command line tools v 12.2 after I installed mongodb v 4.0 with Homebrew. Because I the only one person who faced with the issue, you probably may close the ticket until someone reproduce it.
