Solution: Will be fixed in version 1.4. Meanwhile try to replace in tools/cloud.c, line 960:

  out->nreff  = calloc (nlambda, sizeof(int));

by

  out->nreff  = calloc (nlambda, sizeof(size_t));

and recompile uvspec.

Some users of 64bit machines or in particular Macintosh with OSX reported problems when running sdisort (“bus error”).

Solution: Will be fixed in version 1.4. Meanwhile please replace src_f/dpsdisort.f with dpsdisort.f.

Solution: When compiling uvspec, please make sure that you have all required compilers and tools installed, see Download. For the newer versions of Linux, some of the standard tools are no longer installed by default (as modern users don't want to fiddle around with such ugly things as compilers etc). One particular example is Flex - The Fast Lexical Analyzer. Is usually available for all flavours of Linux, under Mac, and for cygwin, but not necessarily installed by default. You may have to select installation of flex manually. If you have tried compiling uvspec without having flex installed, you may need to remove tools/*_lex.c.

In principle flex shouldn't be needed to compile uvspec, but in release 1.3 we forgot to include uvspec_lex.c. You may download it here and copy to the tools directory. Then uvspec should compile even if you don't have flex installed.
