Cannot build site - Make fails

[amirmc]

I'm not sure if this is an OPAM-related issue or just some quirk on my machine but running make fails.

amir$ make VERBOSE=1
ocaml setup.ml -configure 
Cannot find file topfind.
Unknown directive `require'.
make: *** [setup.data] Error 2
amir$ 

I have all the dependencies as listed in the readme (specifically: oasis, weberizer, Ocamlnet and OCamlRSS).

I'm using the master branch of the ocaml.org repo and am on a Mac 10.8.4

Did you run the following command before running make?

eval `opam config env`

[amirmc]

Interesting. I ran make in a completely new shell and that's where I got the output above. When I run the eval command and try again I get a different error.

amir$ eval `opam config env`
amir$ make
ocaml setup.ml -configure 
ocamlfind: Package `rss' not found
W: Field 'pkg_rss_version_ge_2_2_0' is not set: Command ''/Users/amir/.opam/4.01.0dev+trunk/bin/ocamlfind' query -format %v rss > '/var/folders/gd/bdnlf1ld21g4ynlctmqgml5h0000gn/T/oasis-7ac3a1.txt'' terminated with error code 2

After some hunting, I've also found my way to https://github.com/OCamlPro/opam-repository/issues/34 which seems relevant.

PS: note that it's looking in a different switch (4.01.0dev+trunk). Something didn't work right so this is partially an opam issue.

[pw374]

It's because you're not using opam if you haven't run that eval command. Then, you need ocamlrss : opam install ocamlrss (And then, you might need more packages but let's go step by step...)

[amirmc]

I have all the required packages and I should be on the system switch (see below)

you still have a stale setup.data file that is pointing to the wrong compiler.

you are on the system compiler here:

system C system System compiler (4.00.1) 4.01.0dev+trunk I 4.01.0dev+trunk latest snapshot of the 4.1 branch and then your actual error points to the 4.01 compiler ocamlfind: Package `rss' not found W: Field 'pkg_rss_version_ge_2_2_0' is not set: Command ''/Users/amir/.opam/4.01.0dev+trunk/bin/ocamlfind' query -format %v rss > '/var/folders/gd/bdnlf1ld21g4ynlctmqgml5h0000gn/T/oasis-7ac3a1.txt'' terminated with error code 2

So if you

$ rm setup.data $ make clean $ make

it should rerun configure and point to the right area.
