How to reproduce it:
Try building against external tdlib.

Environment:

• Version: nchat 5.15.26, tdlib 1.8.65
• OS / distro: macOS 10.15.8

[barracuda156]

Fails in the same way with clang-22 as well.

FWIW, also same error with gcc-14 and libstdc++:

tdlib 1.8.65 is targetted to be integrated into nchat this coming weekend.

If you'd like something to test with you can apply attached preliminary integration patch.

nchat-tdlib-1.8.65.patch

Btw, would you mind sharing how you built with an external tdlib? I don't recall if there's a straight-forward way to do it (except overwriting the lib/tgchat/ext/td content (using ./utils/tdlib-update for example).

[barracuda156]

tdlib 1.8.65 is targetted to be integrated into nchat this coming weekend.

I think the error is not specific to 1.8.65 (I just meant to say that I did try the latest release). Originally tdlib was merged in v. 1.8.41, and I got the same failure on Catalina. Then I updated tdlib, and it did not solve the issue.
Not sure what goes wrong; it seems you keep tdlib source unpatched? My x86_64 build is also unpatched, powerpc patch is only used on powerpc (but the failure is the same on both archs).

Btw, would you mind sharing how you built with an external tdlib?

I do not know if it will link, because the build fails on either of my systems, but I think it is sufficient to a) not add the directory, b) if needed, set include path (redundant for MacPorts, default path works) and correct lib name for linking, c) do not try to install tdlib from nchat.

This is not in the main branch and just a draft: macos-powerpc/powerpc-ports@fdb7d0f
The relevant part of the patch is minimal (I do not need to do it conditionally, but it is easy to add an option).

Library name is changed because we do not have tdclientshared, in fact the dylib is not installed at all (which is probably tdlib build system bug):

/opt/local/lib/libtdactor.a
/opt/local/lib/libtdapi.a
/opt/local/lib/libtdclient.a

/opt/local/lib/libtdutils.a

(No idea why only json lib has both static and dynamic version: not something me or MacPorts build system forced.)

As I mentioned, this could not be tested yet, so I can only say that it starts compiling against external tdlib. But in any case, it should not be hard to tweak CMakeLists accordingly.

[d99kris]

Haven't had time to look at this, but just wanted to address this questions:

it seems you keep tdlib source unpatched?

nchat applies some small changes to tdlib, you can see them in utils/tdlib-update. The main part is adding the following to lib/tgchat/ext/td/CMakeLists.txt (providing a shared library target):

# nchat additions start
add_library(tdclientshared SHARED td/telegram/Client.cpp td/telegram/Client.h td/telegram/Log.cpp td/telegram/Log.h)
target_include_directories(tdclientshared PUBLIC
  $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}>
 )
target_link_libraries(tdclientshared PUBLIC tdcore)
# nchat additions end

Then there are some build warning fixes via SEDCMD which should have no functional impact.

[barracuda156]

Ok, that explains the name which sounded odd to me, but it won’t impact compilation in a way we observe.
