libsdl @1.2.15_2 +universal build failure - clang segfault

[bs1464@…]

I have libsdl 1.2.15_0 and I have tried everything that was advised on the ticket guide, but no luck.

It fails during build. It cannot do some changig directory(?) according to the log. (Error: org.macports.build for port libsdl returned: command execution failed)

My aim is to install vxl, not libsdl, so if I could just skip upgrading libsdl, that would be the best for me. Cheers.

Please ​clean libsdl and try again. Also let us know what version of Xcode and clang you have. Find the Xcode version by getting info on the Xcode application; find the clang version by running "clang -v".

And check if you have a crash report in /Library/Logs/DiagnosticReports that you can attach.

[bs1464@…]

Thank you for looking into my problem!

clang -v returned:

clang version 3.1 (branches/release_31) Target: x86_64-apple-darwin11.4.2 Thread model: posix

my XCode version is 4.5.2 (4G2008a)

I have tried to clean libsdl and update many times, did not work. Is it normal that clang -v returned 3.1 while I normally compile with Apple LLVM 4.1?

[bs1464@…]

Today for some reason now the following lines seemed to work:

cv /Library/Logs/DiagnosticReports
sudo port install libsdl
port clean libsdl
sudo port clean libsdl
sudo port install libsdl

After the last command I saw the following feedback:

I have tried exactly the same two days ago and it did not work. Im not sure what made the difference. From my side you can close the ticket, I attach a chrashreport here if you wish to do further investigation.

Thanx Barna. :)

Your port didn't compile this time around; it fetched an archive and installed directly. Also note that it installed libsdl +x11, not libsdl +x11+universal.

clang -v returned:

clang version 3.1 (branches/release_31)
Target: x86_64-apple-darwin11.4.2
Thread model: posix

my XCode version is 4.5.2 (4G2008a)

I have tried to clean libsdl and update many times, did not work. Is it normal that clang -v returned 3.1 while I normally compile with Apple LLVM 4.1?

That doesn't look like Apple's clang. Can you run /usr/bin/clang -v?

[bs1464@…]

Hang on, I must have used clang_select a while ago.
How can I change settings back to default? It seems to be the root cause of the problem, now vxl building also crashes.

btw. /usr/bin/clang -v reports:

Apple clang version 3.0 (tags/Apple/clang-211.12) (based on LLVM 3.0svn) Target: x86_64-apple-darwin11.4.2 Thread model: posix

[jmroot (Joshua Root)]

That's a much older version than the one that comes with Xcode 4.5.2. Update your Command Line Tools via the Xcode preferences.

[bs1464@…]

Yes, I did so. Now, my clang -v is

Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.4.2
Thread model: posix

and got rid of clang ports+system restart.

sudo port clean vxl
sudo port install vxl

aand... no luck, still crashing at the middle of vxl build... :( Should I rather open a new ticket for vxl? I attach here the log. Should I open a new ticket for vxl? I'll attach here the crash log.

[jmroot (Joshua Root)]

Yes, please open a separate ticket for vxl. The log you just attached seems to be incomplete and doesn't show any crash, BTW.

Replying to jmr@…:

Yes, please open a separate ticket for vxl.

The vxl ticket is #37547.
