botan +universal: build failure

[TheLastLovemark]

Initial port -v -d install libkdcraw +docs +universal build failed, cleaned botan and tried to rebuild botan only. That failed too.

botan log file attached.

[kencu (Ken)]

what is your exact current SDK setup, please?

[kencu (Ken)]

$ port -v installed botan
The following ports are currently installed:
  botan @2.10.0_1+universal (active) platform='darwin 17' archs='i386 x86_64' date='2020-01-11T07:47:34-0800'

[TheLastLovemark]

I have SDK 10.13.4 and 10.14

10.14 = the default SDK installed with XCode 10.1/CLT for XCode 10.1

[TheLastLovemark]

does the build look for all available SDKs? or does it start on the first one it finds?

[kencu (Ken)]

Did you undo all that sdk renaming you did?

[jmroot (Joshua Root)]

:info:build ld: warning: ignoring file /opt/local/lib/libbotan-2.dylib, file was built for x86_64 which is not the architecture being linked (i386): /opt/local/lib/libbotan-2.dylib

Nothing to do with SDKs, it's incorrecty linking against an already-installed non-universal version of itself.

[TheLastLovemark]

@Ken: Yes.

MacOSX10.14.sdk <--- default symlink name

MacOSX.sdk <--- actual 10.14 SDK files

MacOSX10.13.sdk <--- 10.13 SDK files extracted from the official 9.4.1 CLT pkg file

@Joshua Root: How do I fix?

[kencu (Ken)]

ok. Just uninstall or deactivate the previous non-universal botan then pls, and you should be ok.

[TheLastLovemark]

botan +universal successfully installed after uninstalling botan.

attempting install of libkdcraw again

[kencu (Ken)]

not sure what Josh & Ryan might want to do with this ticket. Ideally Botan would not link against the already-installed version, but lots of ports have this issue...

Replying to kencu:

I got botan installed, but still having problems with libkdcraw. I'm fine with this ticked being closed as the botan issue is resolved.

[jmroot (Joshua Root)]

Really don't like closing these kinds of issues without doing anything, because they will just crop up again and again. Even adding a new symbol to the library and using it in the executable will cause the build to fail in the not-uncommon event that the old version is installed while building. The build system is broken and at minimum upstream should be notified.

[kencu (Ken)]

a potential universal fix, that works with arm64/x86_64 at least:

​https://github.com/macports/macports-ports/pull/17135

not tested to see if it fixes the situation where an older or different botan library is already installed, but wouldn't expect it to, if that is still an issue.
