Build error on openSUSE 15.3 #65

Closed drmpjz closed 3 years ago

drmpjz commented 3 years ago

Build environment:

openSUSE 15.3

ocaml 4.05.0 ocamlbuild 0.14.0

hevea 2.35 source code

make builds a long list of modules (so in principle build environemnt seems to be sane :-) ) , but eventually fails with

/usr/bin/ocamlopt.opt -c -w +a-3-4-9-41-45-67 -annot -safe-string -o length.cmx length.ml File "length.mll", line 67, characters 41-52: Error: Unbound module Float Command exited with code 2. make: *** [Makefile:57: ocb-opt] Error 10

Any hints how to fix this would be appreciated.

OCaml 4.05 has no Float module (and no round function either).

You could ...

upgrade your OCaml system,
write your own round function, or
in this particular case, i.e. Hevea module Length, you could get away with simply removing the calls to Float.round.

Thanks a lot! That was exactly what I needed. I checked the rolling-release version of openSUSE (Tumbleweed), looks like an upgrade to ocaml 4.12 is in the works there. With this version hevea 2.35 completes the compile (albeit with a few warnings). Short term workaround (remove Float.round) applied and build completes without issues on my main system(s).
