HandBrakeCLI @0.10.0_0: cannot link to libiconv

[stanimura]

HandBrake 0.9.8 would not be built on MacPorts 2.1.2 and MacOSX 10.7.5. It seems a problem involved in linker command.

This is usually due to using the headers from the MacPorts version of libiconv and the library from the system version, or vice versa.

comment:ticket:37434:6 states that upgrading to Xcode 4.5.2 fixes this problem. Can anyone here confirm? Be sure to also upgrade the version of the command line tools; to do that, open Xcode app, go to the Preferences window, and go to the Downloads section. Before you do so, please tell us what version of Xcode you had before that would not build HandBrake.

I have XCode 4.2.1 build 4D502 and have the linking problem. I will update XCode and let you know if it helps.

[ryandesign (Ryan Carsten Schmidt)]

Knowing the version of clang you're seeing the problem with (run "clang -v") would be even more helpful than the Xcode version; I should have asked for that before.

I activated XCode Version 4.5.2 (4G2008a) and removed 4.2.1, but this did not help.

[ryandesign (Ryan Carsten Schmidt)]

And you updated the command line tools and now have a newer version of clang? And you cleaned the HandBrake port before trying again?

I did clean the HandBrake port before trying again but had not updated the command line tools.

So after installing the XCode command line tools (OS X Lion) for XCode - November 2012 (xcode452cltools10_76938212a.dmg):

So it seems the linking error with libiconv has disapeeared indeed. I'll have to investigate why it is still failing. Thanks for the help.

After r132827, this is only a problem with HandBrakeCLI on Snow Leopard. (HandBrake cannot build on Snow Leopard at all.) Leaving this open until I fix it or give up.

** BUILD FAILED **

this error on 10.6.8 occurs because xcodebuild is trying link against the libiconv.dylib in the SDK

$ nm libiconv.dylib | grep close
                 U _fclose
000000000000bd17 T _iconv_close

instead of the one in `/opt/local/lib'

$ nm libiconv.dylib | grep close
000000000000c927 T _libiconv_close

So xcodebuild has to be forced to use the link libraries in /opt/local/lib preferentially, and fall back to the SDK.
