For default-lib-dir, pre-install expects a list of "path" objects

[pcoutin]

I got the following message while trying to raco install:

raco setup: pre-installing: <pkgs>/racket-zmq
path-list-string->path-list: contract violation
  expected: (listof path?)
  given: '(".")
  context...:
   path-list-string->path-list
   /usr/share/racket/racket/pkgs/make/setup-extension.rkt:101:0: 

It'd make more sense for it to be in "/usr/lib64" for me (since I'm on Slackware 64)

For whatever reason, "." (corresponding to the default-lib-dir on the pre-install function) was making it break somehow, in code that only runs when the PLT_EXTENSION_LIB_PATHS variable is defined.

Oh. So (path?) only returns true for something like (path? (string->path "/")), not (path? "/") in Racket 6.2. Wha.

I just set it to (string->path "/usr/lib64"), it could be set to (string->path ".").

I still had this error

raco setup:   extension-installer: can't find needed include files and/or library; try setting the environment variable PLT_EXTENSION_LIB_PATHS
raco setup: error: during making for <pkgs>/racket-zmq
raco setup:   racket-zmq/unsafe/define.rkt:7:9: cannot open module file
raco setup:     module path: zmq/ext

raco setup:     system error: No such file or directory; errno=2
raco setup:     compiling: <pkgs>/racket-zmq/unsafe/define.rkt

even after settting PLT_EXTENSION_LIB_PATHS and LD_LIBRARY_PATH to /usr/lib64 The only thing that worked so far was cp /usr/lib64/libzmq.so.1.1 /usr/lib/libzmq.so more messages of it 'working'

The compiled extension finds libzmq on /usr/lib64, that's good

[dedbox]

So default-lib-dir is a path-string?, which means the string->path conversion should be automatic. Sounds like a bug in the make/setup-extension module.

Did you try changing "." to "/usr/lib64" directly?

[pcoutin]

Yeah Tried both racket 6.2 and 6.2.1 Maybe PLT_EXTENSION_LIB_PATHS should've started with ":"? (like the instructions say for PLTCOLLECTS) I just moved libzmq.so to /usr/lib, compiled and removed it, it's fine now... ...
