inkscape: gcc >= 3.0 is needed to compile inkscape

[fbartolom@…]

When I try to upgrade or reinstall Inkscape I get the following error:

$ sudo port install inkscape
Warning: No port atlas found in the index.

Please remember to use WikiFormatting and to Cc the maintainer of the affected port.

What version of Xcode is installed? Try reinstalling the latest version of Xcode for your OS version.

I confirmed this problem on Xcode 4.2 GM/Lion.

So I guess the original reporter was using clang 3.0 as a compiler.

$ clang --version
Apple clang version 3.0 (tags/Apple/clang-211.10.1) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin11.1.0
Thread model: posix

Although I don't have Lion installed, I was able to confirm the problem on XCode 4.1/SL as well by setting

configure.compiler clang

The gcc version check in configure fails, not because the clang version is 3.0 or less (2.1 in XCode 4.1) but because the check is looking for a line with the string 'gcc version' in the output of 'clang -v' which it never finds. This sets results in the extracted major version being set to 0.

I tried disabling this check in the case where clang is the compiler and configure completed successfully, but the build phase fails miserably using clang.

Attached is a patch for the port file that sets the compiler to llvm-gcc-4.2 if the selected compiler is clang. This works for me but needs to be tested on Lion.

Please let me know if this works on Lion or if not what modifications to make.

Thanks

Patch to use llvm-gcc-4.2 instead of clang

Patch to use llvm-gcc-4.2 instead of clang

It works fine on Xcode 4.2/Lion. :-)

Fix committed in r85061, thanks.
