cannot build

[giuliomoro]

Just now I cannot build. All the object files are generated, but both sclang and scsynth fail to link properly. I followed the instructions in the README, anything else I should do?

I am on 2bbfa5f21e406388fc40e14274214bed29635231

scsynth fails to link as follows:

Hmm... this is strange... I have for sure built that version and tested (although it was a rebuilt, not a fresh one). Are you sure it is not trying to link to an older library (like one preinstalled on the image)?

Fixed: I think something went wrong while during the build, so server/scsynth/libscsynth.a existed but was empty. So that was considered up-to-date by make, but then it would not be able to find any symbols in it when using it for linking. I deleted it and now it works!
