ghostscript 9.19 build fails

[bruce-r-sutherland]

ghostscript 9.19 fails to build for me with MacPorts 2.3.5 on MacOS Sierra desktop computer. I have uninstalled and reinstalled, clean all ports, etc but the problem persists. From the main.log file, the problem is a percieved error with line 423 in /usr/include/pthread.h.

Key lines in main.log are:

:info:build In file included from ./base/gp_psync.c:21:
:info:build /usr/include/pthread.h:423:25: error: expected parameter declarator
:info:build __SWIFT_UNAVAILABLE_MSG("Use lazily initialized globals instead")
:info:build                         ^
:info:build /usr/include/pthread.h:423:25: error: expected ')'
:info:build /usr/include/pthread.h:423:24: note: to match this '('
:info:build __SWIFT_UNAVAILABLE_MSG("Use lazily initialized globals instead")
:info:build                        ^
:info:build /usr/include/pthread.h:424:51: error: expected ';' after top level declarator
:info:build __OSX_AVAILABLE_STARTING(__MAC_10_4, __IPHONE_2_0)

Strangely, I do not have a problem compiling the save version of ghostscript on my laptop even though the pthread.h file is identical.

Help would be appreciated. Full main.log file is attached

What is the output of these three commands?

xcode-select -print-path
xcodebuild -version
/usr/bin/clang -v

Try reinstalling the latest version of the command line tools (which is what provides the files in /usr/include).

Unfortunately, this did not work. I uninstalled command line tools using sudo rm -rf /Library/Developer/CommandLineTools, then reinstalled using sudo xcode-select --install. Then I tried once more to install ghostscript having previously uninstalled and cleaned the port: sudo port install ghostscript. I get the same error in main.log with pthread.h as reported above.

Hi Bruce, Did you ever resolve this? I can't confirm 100% because I did this seredipitously, but I believe I had old copies of /usr/include/Availability*.h in /opt/local/include. Removing them seems to have allowed a bunch of builds to proceed. I haven't gotten to ghostscript yet, though.

What I did exactly:

Read https://trac.macports.org/ticket/48471. As suggested there
Copy /usr/include/Availability.h to /opt/local/include.
Try to edit them but this didn't work because the configuration of bad #ifdefs in
    48471 wasn't present.
Deleted them because it's unclean to have them around.
"Oh! Maybe I had wrong ones there!", retry the upgrades and voilà! compile happened.

[bruce-r-sutherland]

Thanks for the suggestion. In the end I took the drastic step of deleting all my ports (effectively uninstalling MacPorts) and reinstalling everything. This did the trick.
