I just ran cabal install Shake to install the latest release.

What I get is:

cabal: Error: some packages failed to install:

Does anyone has an Idea?

Kind regards

I had to install a newer version of ghc in order to update unordered-containers to 0.2.9 (0.2.8 was not enogh)

[Neil Mitchell]

Hi Lukas,

Sorry for the issue!

Which version of GHC were you previously on? What was the failure when
building with 0.2.8? I just checked the dependency information and
came to the conclusion that 0.2.7 should be sufficient.

Thanks, Neil

[Neil Mitchell]

Hi Lukas,

I was able to build with 0.2.7, so I'm pretty sure that's the minimum
lower bound. I have revised shake-0.16.1, and also pushed out
shake-0.16.2 with the fix properly committed.

Thanks for letting me know, most appreciated!

Thanks, Neil

[Lukas]

Sorry accidentally I did not answer to the mailing list first.

Yes you are right, at that time I had two versions and I took an incorrect version 0.2.8-version. I was first using a pretty old pre-installed version (I think it was a 7.6.3 version). Thanks a lot for the update.

I have now tested shake with my project (using build.ninja as a start). Unfortunately it did not work with those targets generated with CMAKE_AUTORCC. For all those targets, I get the following error:

> shake -VV
# Project
# CMakeFiles/Project.dir/CMakeFiles/Project.dir/qrc_resources.cpp.o
# CMakeFiles/Project.dir/qrc_resources.cpp
# CMakeFiles/Project_automoc CMakeFiles/Project.dir/qrc_resources.cpp

shake: Error when running Shake build system:
* Project
* CMakeFiles/Project.dir/CMakeFiles/Project.dir/qrc_resources.cpp.o
* CMakeFiles/Project.dir/qrc_resources.cpp
Prelude.!!: index too large

I have reduced the problem to the following simple standalone build.ninja:

ninja_required_version = 1.5
build test : phony a b
rule CUSTOM_COMMAND
command = $COMMAND
build a b : CUSTOM_COMMAND
COMMAND = cd

With ninja, this works without an error. With shake I get:

# cd (for a b)
shake: Error when running Shake build system:
* b
Prelude.!!: index too large

This is caused by Internal/Rules/Files.hs, Line 187. I have no idea what to change.

Best, Lukas

Hi Lukas,

Thanks for the test case - that's awesome! I'll take a closer look.
I've raised a bug at https://github.com/ndmitchell/shake/issues/565,
partly so that any updates etc as a result are recorded in one central
place.

Thanks, Neil

[Neil Mitchell]

Hi Lukas,

The issue is now solved, and I've updated the ticket. The problem is
that Ninja rules don't have to create their contents - so even though
build a b says it creates a and b, it actually doesn't. Shake on the
other hand demands that files are created. There is a flag for Shake
to have Ninja compatible behaviour, but I had messed it up in relation
to multi-file rules, and since it's only used through the Ninja
pieces, I hadn't noticed.

Given you are using Shake for the Ninja stuff, would it be convenient
if I uploaded shake.exe binaries to github? Then you could avoid
compiling Shake yourself.

Thanks, Neil

Hi Neil,

Thanks for solving the issue! I also detected this such my horrible but quick workaround was to just create these files (CMake generates a ninja-rule CUSTOM_COMMAND with "command = $command", which I then extended to command = touch $out; $command). I will try the new version tomorrow, but I am quite certain that everything works great by now.

I think given that many people will not have a preinstalled ghc, providing the executables would lower the hurden a lot to just give shake a try. Additionally, your ninja-backend has the benefit of quite useful report that is generated, which is a great argument for your build system.

Therefore, I think there is nothing against uploading a compiled version for the common operating systems.

Best, Lukas
