gnucash @3.9: Could NOT find Threads (missing: Threads_FOUND)

[hapaguy (Brian Kurt Fujikawa)]

I am using the following:

• macOS 10.15.4
• Xcode 11.4
• MacPorts 2.6.2

The gnucash build fails:

• sudo port -sv upgrade gnucash
• sudo port -sv install gnucash

with missing threads, etc.:

• -- Performing Test HAVE_OFX_BUG_39 - Failed
• -- Performing Test have_stringop_truncation - Failed
• -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed
• -- Looking for pthread_create in pthreads - not found
• -- Looking for pthread_create in pthread - not found

I have attached the main.log.

I agree; here's the ​build failure log from our Catalina buildbot worker. This problem appears to be specific to Catalina.

Could you also attach the CMakeError.log file?

Could you also attach the CMakeError.log file?

done, thanks

Well, I'm pretty confused here because I didn't run into this problem when I originally prepared the gnucash 3.9 update (also on Catalina), but now I'm running into it with gnucash 3.10. I guess this is probably related to some update either to Catalina or to Xcode that happened in the interim??

FWIW, I updated macOS and Xcode on Mar 24 - a week before I ran into problems with the gnucash 3.9 update. I didn't encounter any issues with the gnucash 3.8 update in Jan - so, your guess that the problem is related to the macOS/Xcode update is reasonable.

I notice one pthread.h test fails like this:

error: no previous prototype for function 'test_func' [-Werror,-Wmissing-prototypes]

I'd have to check by comparing to some other compiler's behaviour, but it could be that test used to pass, and now it fails due to a stricter clang syntax check.

With clang-9 on 10.6, I see similar errors, but it succeeds in the end:

-- Checking for GTEST
-- Looking for pthread.h
-- Looking for pthread.h - found
-- Performing Test CMAKE_HAVE_LIBC_PTHREAD
-- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed
-- Check if compiler accepts -pthread
-- Check if compiler accepts -pthread - no
-- Looking for pthread_create in pthreads
-- Looking for pthread_create in pthreads - not found
-- Looking for pthread_create in pthread
-- Looking for pthread_create in pthread - found
-- Found Threads: TRUE  

so it's not that -- too bad, that might have been easy. You may see useful information in CMakeOutput.log to help as well.

I'd appreciate some movement on this one. I've been using direct download of gnucash from the upstream site, but I am experiencing some weird behavior that might be easier to trouble-shoot with Macports-installed gnucash. I googled and tried solutions suggested on these forums/issues:

​https://github.com/fireice-uk/xmr-stak/issues/1597

but no luck. I'm willing to try other things if you have suggestions.
