unbound @1.4.2 doesn't configure +universal

[neverpanic (Clemens Lang)]

Unbound doesn't succeed the configure phase when installing with +universal.

Configure fails at finding ldns.h, although it's installed.

config.log showing the error messages causing the problem

[nerdling (Jeremy Lavergne)]

This is the normal test: configure:16789: /Developer/usr/bin/llvm-gcc-4.2 -c -pipe -O2 -arch x86_64 -g -O2 -flto -D_THREAD_SAFE -I/opt/local/include -I/opt/local/include conftest.c >&5

This is the universal test: configure:16789: /Developer/usr/bin/llvm-gcc-4.2 -c -pipe -O2 -arch x86_64 -arch i386 -g -O2 -flto -I/opt/local/include -I/opt/local/include -I/opt/local/include conftest.c >&5

successful build on Snow Leopard with Xcode 3.2.6

[ryandesign (Ryan Carsten Schmidt)]

Interesting: it builds fine universal for me, on Snow Leopard with Xcode 3.2.6.

[ryandesign (Ryan Carsten Schmidt)]

But I am able to reproduce the failure on the same system with configure.compiler=llvm-gcc-4.2.

The relevant lines in config.log seem to be these:

configure:16789: checking for ldns/ldns.h
configure:16789: /Developer/usr/bin/llvm-gcc-4.2 -c -pipe -O2 -arch x86_64 -arch i386 -g -O2 -flto -I/opt/local/include -I/opt/local/include -I/opt/local/include conftest.c >&5

Try using clang; if also fails, use gcc-4.2 / apple-gcc-4.2. If you're sure it works fine with llvm-gcc-4.2 and clang when built non-universal, you could enclose that compiler block in a if {[variant_isset universal]} block, to avoid making people install the apple-gcc42 port unnecessarily if they're not building universal.

[nerdling (Jeremy Lavergne)]

Clang does not appear to work either. Ryan, can you file a radar for this please?

[nerdling (Jeremy Lavergne)]

Apple clang version 2.0 (tags/Apple/clang-139) (based on LLVM 2.9svn)

i686-apple-darwin10-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.9)

ProductName:    Mac OS X Server
ProductVersion: 10.6.8
BuildVersion:   10K549

[nerdling (Jeremy Lavergne)]

+unviersal requires gcc, r87102.

Replying to snc@…:

Ryan, can you file a radar for this please?

I could enter a report at ​http://bugreport.apple.com, but you could too...

[nerdling (Jeremy Lavergne)]

As of r89571 (unbound @1.4.16) llvm and clang work for normal compiling, but only llvm can now handle +universal.

[ryandesign (Ryan Carsten Schmidt)]

unbound 1.4.16 seemed to build fine universal for me on Snow Leopard with Xcode 3.2.6 and therefore gcc-4.2.

[nerdling (Jeremy Lavergne)]

Thanks for the SL input, which indicates no changes needed (clang only being on Lion). I tried all my combinations in a Lion VM.

[ryandesign (Ryan Carsten Schmidt)]

clang would also be used on Snow Leopard if the user had installed Xcode 4.2.

[nerdling (Jeremy Lavergne)]

So Snow Leopard has all three compilers with Xcode 4.2 (clang, llvm, gcc)?

[ryandesign (Ryan Carsten Schmidt)]

Snow Leopard is no different from Lion in that regard. Xcode 4.2 does not include gcc. The different is that on Snow Leopard Xcode 4 is not free; the latest free version is 3.2.6.
