No tup entry for config/macosx

[hoosierEE]

System is: Mac OSX 10.11.2

Note that I installed tup via Homebrew, which required two steps due to some kext permission thing:

$ brew install Caskroom/cask/osxfuse
$ brew install homebrew/fuse/tup

Here is the full output:

$ tup

Tried on the develop branch to be thorough; same error:

Ah well I now have a very rudimentary understanding of Tup and this error is simply saying that we haven't yet made a config/macosx file for Tup to read.

That's right, we need to make a config/macosx file. I imagine it should be very similar to the linux file. If you want to try it out, copy the linux file, then I can help you fix any issues if you paste the output here.

[hoosierEE]

Maybe making progress, not sure yet.

Merely changing the *.so into *.dylib is not sufficient to produce a working executable on OSX.

One issue I noticed so far:

In the file hostdefs.sym the line <pcreposix.h> should be "pcreposix.h" because it's a local include. This requires a change to sym2ijs.ijs because it's currently only looking for header files wrapped in angle brackets <likethis.h>.

I'll give it a go tomorrow if I have time.

[iocane]

I had the same problem with the sym2ijs script. Instead of changing it, I just added -an I option to gcc to tell it to search for headers in that directory. Maybe it's not being picked up properly or is more strict on Mac. Which compiler are you using?

[hoosierEE]

I have both clang and gcc on that system so I'm not 100% sure, but the Tupfile tests for the presence of clang first so probably clang. Will test tomorrow.

[iocane]

Actually, after looking again I see that I did not add -Isrc/libj/defs to the compile command. I don't know why it works in Linux but the OSX compiler probably treats it differently than gcc on Linux. Try this when you get a chance: change this

: foreach $(defdir)/*.c |> ^ CC %f^ $(CC) %f -o %o |> bin/%B {defs}

to:

: foreach $(defdir)/*.c |> ^ CC %f^ $(CC) -Isrc/libj/defs %f -o %o |> bin/%B {defs}
