I have poked around in the log file, but have not seen anything obvious. I can upload the log file if you wish.

Yes please, the log file would be useful

Build Log File

Taking another look at the log file, I see that a number of tests failed during the configuration stage.

Replying to josephsacco:

Taking another look at the log file, I see that a number of tests failed during the configuration stage.

Specifically?

The configuration process determines the capabilities of your system. It is normal for some tests to report that things are not found.

It is also possible that some configuration tests are making incorrect determinations due to implicit declaration of functions, but we would not be able to know whether that is so without looking at the config.log. Or you could upgrade to MacPorts 2.7.0-beta2 which will print a message at the end of the configure phase if this problem occurs.

The problem I see in the log is:

version:1:1: error: expected unqualified-id

This means you are using a C++20-capable compiler and the VERSION file included in the source is conflicting with the version header of your compiler because you are on a case-insensitive filesystem. See ​https://bugs.llvm.org/show_bug.cgi?id=42540. The consensus seems to be that the correct fix is for the build system not to add the root directory (the one containing the VERSION file) as an include path, but I don't know whether that is easy or hard to do in the MySQL build system.

Is there a specific reason why you need mysql57, which is old? The current version is mysql8.

[josephsacco]

Our "friends" at BlueHost are still using mysql57, at least on shared server accounts. So... I am stuck with version 5.7 for now.

I recently upgraded the operating system and associated Xcode tools and CommandLine tools on my iMac to 11.3. I wonder if the 11.3 upgrade is causing the mischief.

[ryandesign (Ryan Carsten Schmidt)]

Likely, the Xcode upgrade has given you a C++20-capable compiler where you did not have one before.

Finally, this will show up in xcode builds now, and be fixed broadly.

up to now, only 10.6.8 and other systems forced to clang-9.0 were seeing this error all the time.

We have fixed it properly here and there, or sometimes (like some of the mysql ports) just forced it build with an older macports-clang (5-7) that doesn't have this <version> header that causes the conflict.

[ostefano (Stefano Ortolani)]

I can confirm this bug, and indeed it happens only on 11.3. Is there any workaround besides upgrading mysql?

[landabaso]

Same here. We still need to maintain mysql 5.7 and it is now not possible to do so with BigSur. Besides, it's not possible to force compiling with clang below 9 on BigSur either.

Please, could you share any workaround while this is being fixed?

Thanks

In e88dc2b57f85b54b0c02b434576bc11e40cf9aae/macports-ports (master):

mysql57: avoid collision with C++17 header <version>

Fixes #62784
No revbump since port either builds correctly or not at all.
