zlib destroot fails with cp usage message when Xcode is too old

[trichard@…]

Hello,

i just set up a new imac with all up to date Apple software (10.6.3, Macports 1.8.2) and tried to install mysql on the system.

I received the following error:

--->  Computing dependencies for mysql5
--->  Staging zlib into destroot
Error: Target org.macports.destroot returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_archivers_zlib/work/zlib-1.2.5" && /usr/bin/make install prefix=/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_archivers_zlib/work/destroot/opt/local " returned error 2

make: *** [install-libs] Error 64

Error: The following dependencies failed to build: openssl zlib readline
Error: Status 1 encountered during processing.
Before reporting a bug, first run the command again with the -d flag to get complete output.

then I tried to install ffmpeg or ImageMagick and i allways encountered the same message.

so i tried to install zlib... same message.

I've checked the permissions in /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_archivers_zlib/work/zlib-1.2.5 and /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_archivers_zlib/work/destroot/opt/local

everything seems to be ok.

What's going wrong with the zlib installation?

Thanks in advance

Thomas

Please remember WikiFormatting and to Cc the port's maintainers.

It looks like while it's having no trouble with the static library, it's having problems installing the shared library; looks like the Makefile variable SHAREDLIBV is empty for some reason.

Please clean and try again and use the debug switch:

sudo port clean zlib
sudo port -d install zlib 2>&1 | tee ~/Desktop/zlib.txt

Assuming it fails again, please attach the file zlib.txt from your desktop to this ticket so I can see everything that's going on.

Replying to ryandesign@…:

Please clean and try again and use the debug switch:

sudo port clean zlib

That was the solution.

Don't know where it lost the variable

Thanks a lot, ticket can be closed.

Ok, glad you got it working.

This problem was also reported in #24896.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #25125.

[ryandesign (Ryan Carsten Schmidt)]

Through discussion in #25125 I believe this problem occurs when users try installing zlib while a too-old version of Xcode is installed (e.g. Xcode < 3.2 on Snow Leopard), then upgrade Xcode, then continue trying to install zlib without first cleaning zlib.

[ryandesign (Ryan Carsten Schmidt)]

Fixed in r68569 by checking that a valid Xcode version is installed. MacPorts 1.9.0 will also fix this problem because it has such checks built in for all ports.
