Re: [eclipse-clp-users] ECLiPSe 7.0#49 compilation errors on macOS

Hi,

The -mmacosx-version-min=10.5 was indeed the problem. Changing configure to use 10.8 instead resulted in a successful compilation. For reference, I'm running macOS Mojave (10.4.6) with Xcode 10.3:

$ gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/c++/4.2.1
Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.7.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Thanks for all the help.

Cheers,
Paulo
