zlib: can't build with Xcode 4.3

[webmaster@…]

Hi,

I just bought a new MacBook Air with Mac OS Lion running (v10.7.3). I have installed XCode, xcode-select -version shows v2307, and also installed MacPorts. Then I ran the selfupdate command to update the port tree.

When I try to install apache2, the build fails when building the zlib dependency. Below is the output:

$ sudo port install -d zlib
--->  Fetching archive for zlib
--->  Attempting to fetch zlib-1.2.6_0.darwin_11.x86_64.tbz2 from http://packages.macports.org/zlib

Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

The zlib log file says:

:info:build shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_archivers_zlib/zlib/work/zlib-1.2.6" && /usr/bin/make -j4 -w all " returned error 2

Any hints for helping me please?

None of the output you showed is helpful for determining what happened. Attach the main.log file.

What version of Xcode are you using? If 4.3, I recommend you downgrade to 4.2.1 until we have time to fix various things in MacPorts that make it currently problematic to use 4.3.

Hi,

I had Xcode version 4.3, so I downgraded to 4.2.1 and the problem still occurs.

The mail log says that:

"command_exec build"
    (procedure "portbuild::build_main" line 8)
    invoked from within
"$procedure $targetname"
:info:build Warning: the following items did not execute (for zlib): org.macports.activate org.macports.build org.macports.destroot org.macports.install
:error:build Failed to install zlib
:debug:build could not read "/opt/local/lib/pkgconfig/apr-util-1.pc": no such file or directory
    while executing

:notice:build Log for zlib is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_archivers_zlib/zlib/main.log

Any ideas? (I use Mac OS X 10.7.3 by the way)

[mkhalil.sarah@…]

*main.log, not mail, sorry.

[ryandesign (Ryan Carsten Schmidt)]

I have a feeling the real error is earlier than that in the main.log. But probably the problem is you did not clean after downgrading Xcode. Try:

sudo port clean zlib

Then try again.

[mkhalil.sarah@…]

It works perfectly! Thank you very much :)

[ryandesign (Ryan Carsten Schmidt)]

Great, glad you got it working.

[zstefan@…]

I have a similar problem, but sudo port clean zlib / didnt work in my case How to downgrade to xcode 4.2.3?

thats the main.log

Uninstall Xcode 4.3, following whatever instructions Apple provides to do that. Then install Xcode 4.2.1. If you no longer have the Xcode 4.2.1 installer, download it from ​http://connect.apple.com

[sholaykabab@…]

Do this:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

[drkp (Dan Ports)]

Xcode 4.3 should work with MacPorts 2.0.4; make sure you have that installed (and follow any instructions it gives you about running xcode-select if necessary).

[scanner85@…]

For install zlib I seting xcode-select & adding symlink:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer 
cd  /Applications/Xcode.app/Contents/Developer/usr/bin/
ln -s llvm-gcc-4.2 clang
sudo port install -d zlib

And all OK.

May be better set CC=gcc for environment.

Replying to scanner85@…:

For install zlib I seting xcode-select & adding symlink:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer 
cd  /Applications/Xcode.app/Contents/Developer/usr/bin/
ln -s llvm-gcc-4.2 clang
sudo port install -d zlib

Please remove the symlink you created. It does not belong there.

May be better set CC=gcc for environment.

No: On Xcode 4.0 and 4.1 we default to llvm-gcc-4.2. On Xcode 4.2 and up we default to clang. On Xcode 4.2 and up gcc isn't even installed anymore. Individual ports might override that as needed, but to my knowledge, zlib does not need to do so.

This ticket is done; please do not write in it anymore. If you have further questions about how to use MacPorts, please write to the macports-users mailing list.
