[archimedes-discuss] Undefined symbols for architecture x86_64

[Marius Schamschula]

Hello,

I’m trying to update the MacPorts Portfile for archimedes. I’ve run into an 
error similar to that which has been previously reported on StackOverflow:

https://stackoverflow.com/questions/46954677/gnu-archimedes-fails-to-build-undefined-symbols-for-architecture-even-though

In my case I find

make[2]: Entering directory 
`/opt/local/var/macports/build/_Users_marius_Development_MacPorts_ports_science_archimedes/archimedes/work/archimedes-2.0.1/src'
/usr/bin/clang -DHAVE_CONFIG_H -I. -I..   -I/opt/local/include  -pipe -Os -arch

I’m building under macOS 10.13.6 with the current Xcode developer tool chain:

marius$ /usr/bin/clang --version
Apple LLVM version 10.0.0 (clang-1000.11.45.5)
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: 
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Any ideas would be greatly appreciated!
