llvm-3.7: libcompiler_rt.a: No such file or directory

[scottmeup (Andrew Scott)]

Hi, I'm trying to follow the guide listed here: LibcxxOnOlderSystems

At step 7, running the line as written

sudo port -v -n upgrade --force --enforce-variants cctools -llvm34 +llvm39

fails with Error: cctools: Variant llvm39 conflicts with llvm40

running the line modified to include llvm40

sudo port -v -n upgrade --force --enforce-variants cctools -llvm34 +llvm40

gets further but still fails with

In file included from /usr/include/limits.h:64:

/usr/include/machine/limits.h:10:2: error: architecture not supported

#error architecture not supported

and requests that I submit a ticket.

I'm running Snow Leopard 10.6.8 on a Macbook Pro 5,3

The log you attached contains 6 failed build attempts.

The first one failed with these errors:

Build attemps 2 through 6 failed with this error:

:info:build /usr/include/sys/cdefs.h:540:4: error: Unknown architecture

However those build attempt were not clean; they were resuming from the original failed build. As such, I would not pay any attention to the possibly erroneous errors they generated and I would focus on the error generated by the original build attempt.

something is amiss. There is no file with that name in clang-3.7:

I would clean up any partial builds in /opt/local/var/macports/build and then try it again.

[scottmeup (Andrew Scott)]

I cleaned all, and re-installed macports. It seems I have additional problems now:

Step 1

sudo port -v install clang-3.4 ld64 cctools libcxx

[kencu (Ken)]

Yikes. Have to go to baby steps, one thing at a time.

If you can't install clang-3.4, you'll never get anywhere. Clean everything, make sure you start with your macports.conf set to the default values, and try to install clang-3.4. IF that works, then go step by step.

For example, there is no way to proceed on to the next step of anything if the previous step was unsuccessful. You cannot install clang-3.7 without clang-3.4.

[scottmeup (Andrew Scott)]

Here's what I've just run, and the results. Perhaps I'm not entering something correctly?

sudo cp /opt/local/etc/macports/macports.conf.default /opt/local/etc/macports/macports.conf 
sudo port clean --all all

[kencu (Ken)]

Wow. This looks seriously hosed. You could spend a long time fixing this, I guess. I personally would just start over <​https://guide.macports.org/chunked/installing.macports.uninstalling.html> and reinstall MacPorts completely from scratch.

Then install something very simple -- and see if you can get MacPorts working at all.

Unless somebody has a spectacularly better idea...

[scottmeup (Andrew Scott)]

After uninstalling and re-installing MacPorts I've installed a simple port - ircii-classic - without errors. I'll try following the c++11 guide again from this state and post the results.

sudo port -fp uninstall installed

sudo rm -rf \
        /opt/local \
        /Applications/DarwinPorts \
        /Applications/MacPorts \
        /Library/LaunchDaemons/org.macports.* \
        /Library/Receipts/DarwinPorts*.pkg \

        /Library/Tcl/darwinports1.0 \
        /Library/Tcl/macports1.0 \
        ~/.macports

open ~/Downloads/MacPorts-2.5.4-10.6-SnowLeopard.pkg

sudo port selfupdate

port upgrade outdated

sudo port install ircii-classic

main.log from port -v install clang-3.7, run after clean install of macports. 2019-06-19

[scottmeup (Andrew Scott)]

No luck :(

I got up to step 4 without so much as a warning,

Trying to install clang 3.7 ended up spitting out a bunch of architecture errors at the end, I'm not 100% sure where it went wrong. Most recent main.log is attached to this ticket.

The process I most recently ran was:

in terminal

sudo port -fp uninstall installed

sudo rm -rf \
        /opt/local \
        /Applications/DarwinPorts \
        /Applications/MacPorts \
        /Library/LaunchDaemons/org.macports.* \
        /Library/Receipts/DarwinPorts*.pkg \
        /Library/Receipts/MacPorts*.pkg \
        /Library/StartupItems/DarwinPortsStartup \
        /Library/Tcl/darwinports1.0 \
        /Library/Tcl/macports1.0 \
        ~/.macports

open ~/Downloads/MacPorts-2.5.4-10.6-SnowLeopard.pkg

sudo port selfupdate

port upgrade outdated

sudo port -v install libcxx

sudo port -v -f deactivate active
sudo port -v install clang-3.4 ld64 cctools libcxx

Appended the following to /opt/local/etc/macports/macports.conf:

(no uncommented copies of the variables were left in macports.conf)

cxx_stdlib         libc++
buildfromsource    always
default_compilers  macports-clang-3.4 gcc-4.2 apple-gcc-4.2 gcc-4.0
revupgrade_autorun no

then in terminal:

sudo port -v -f uninstall inactive

sudo port -v install clang-3.7

The last command ran for a few hours then exited, giving the log attached.

[kencu (Ken)]

could you give me the output of this command please:

    echo "macOS $(sw_vers -productVersion) $(sw_vers -buildVersion)"; echo "Xcode $(xcodebuild -version | awk '{print $NF}' | tr '\n' ' ')"

macOS 10.6.8 10K549

Xcode 4.2 4C199

[BjarneDMat]

Replying to scottmeup:

Xcode 4.2 4C199 <--- that's the problem !

Xcode 4.2 is seriously hosed when trying to work with MacPorts You'll have to downgrade to Xcode 3.2.6 DevToolsSupport-1806.0 10M2518

I also had Xcode 4.2 installed which gave me lots of problems. Somebody for a long time ago advised me to downgrade to 3.2.6 & since then I've had no problems :-)

[scottmeup (Andrew Scott)]

Thanks @BjarneDMat. successfully completed through step 13 of the guide ​https://trac.macports.org/wiki/LibcxxOnOlderSystems using xcode 3.2.6.

[kencu (Ken)]

Glad you got it working. Must have been something with your setup that was fixed by reinstalling xcode I guess.

BTW, I often use xcode 4.2 on 10.6.8, and never had any issues with it, so I don't personally think it was a problem caused specifically because of xcode 4.2.

closing!

[scottmeup (Andrew Scott)]

Thanks Ken, I'm glad it's working too! I'm not sure about the Xcode situation. All I can tell you is that it was a relatively clean and recent install of 10.6 followed by an update to 10.6.8, followed by an install of Xcode 4.2. I basically dug this machine out of mothballs and wiped it. I hadn't installed any version of Xcode up to the time I was trying to install an IPTV server from source code.
