samba3 @3.6.25 +openldap: lib/memcache.c:29:2: error: unknown type name 'uint8'; did you mean 'uint'?

This is OS X 10.9.5 running "Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)". I believe the relevant parts of the log starts around:

We have packages of samba3 for all macOS versions on our server, so it built successfully for us. Not sure why it didn't build for you. I see you're using non-default variants, including +openldap. That built OK for me on El Capitan. I didn't test Mavericks yet.

I just updated samba3 to 3.6.25. Please wait an hour, then run sudo port selfupdate to receive that change, then try installing again. If it fails again, please attach the new main.log.

[maverickwoo (Maverick Woo)]

Building 3.6.25 fails with exactly the same problem in my config. I have attached the new log file for future reference.

Thanks to your guidance, I was able to avoid the problem by not building the openldap variant, which fortunately does not affect my usage.

I recognize also my build environment is niche (Mavericks +openldap). If you think it is appropriate, we can perhaps even close the ticket.

Thank you!

[ryandesign (Ryan Carsten Schmidt)]

Thanks for confirming that it's the openldap variant that's provoking the problem. We should keep the ticket open until we've fixed that.

The second error in the log is more helpful:

:info:build lib/memcache.c:33:8: error: redefinition of 'memcache'
:info:build struct memcache {
:info:build        ^
:info:build /opt/local/include/memcache.h:551:8: note: previous definition is here
:info:build struct memcache {
:info:build        ^

/opt/local/include/memcache.h is provided by the libmemcache port; I can reproduce the problem on El Capitan if I use the openldap variant when the libmemcache port is already installed.

Ideally we would fix samba3 so that it does not have this problem. At minimum we can use the conflicts_build portgroup to indicate that samba3 has a build conflict with libmemcache when the openldap variant is used.

Building in trace mode helps get around this error; it also leads to the following access reports:
