vaucanson: rename to vcsn and update to 2.1

[akimd (Akim Demaille)]

Hi,

Vcsn 2.1 was released. The package used to be named Vaucanson, it has been renamed as Vcsn, but I don't know how portfiles can reflect this...

Thanks. I assume you are the maintainer of this port? Your email address in this Trac ticket does not match the one listed in the portfile.

MacPorts can accommodate renamed ports. See PortfileRecipes#replaced-by.

You added a library dependency on lib:libltdl:libport but we have no port called "libport". libltdl is part of the libtool port; is that what you meant? If so, it should be written "port:libtool". "lib:"-style dependencies are only used when it is desired to allow non-MacPorts software to satisfy the dependency, and usually we do not desire that.

You added a runtime dependency on port:ccache. Usually ccache is used at build time, at the discretion of the user and their macports.conf settings. Is ccache really needed at runtime? If so, the dependency should be written "path:bin/ccache:ccache" to allow the ccache-devel port to satisfy the dependency.

Some of the compilers you've blacklisted don't exist anymore, for example "*clang-2.*". The oldest clang we have in MacPorts today is clang-3.3.

Since this project requires C++11, it should probably start by using the cxx11 1.0 portgroup, which sets some blacklisting and other necessary options. The blacklist can then be augmented if the project has compiler restrictions above and beyond the need for C++11.

Hi Ryan! Thanks for taking care of this.

I'm the maintainer of Vcsn. Yes, I'm akim@….

OK. I don't know where I took this line from. Note that there is

depends_run         path:lib/libltdl.a:libtool

provided as an example there: ​https://guide.macports.org/chunked/reference.dependencies.html

If so, the dependency should be written "path:bin/ccache:ccache" to allow the ccache-devel port to satisfy the dependency.

OK, I fixed that. Yes, vcsn runs compilation at runtime, and uses ccache to ensure that modules that were previously compiled will no longer be recompiled.

Some of the compilers you've blacklisted don't exist anymore, for example "*clang-2.*". The oldest clang we have in MacPorts today is clang-3.3.

Good to know, thanks!

I have attached two Portfiles: one for vcsn, another for obsoleting Vaucanson. I have also added a new diff from the previous vaucanson Portfile to the new vcsn Port file. Thanks again!

Hi,

Is there something I can/should do to help?

[kurthindenburg (Kurt Hindenburg)]

Cc Me!

Akim, I added this in r144823

I had to make a lot of changes - can you test and let me know if there are any issues? When it works, I'll obsolete the other port.

You can use 'sudo port -t install' which adds --trace which will find dependencies that are needed

also 'sudo port -v test'

Hi!

First, sorry for not being more responsive, I've been too busy lately :(

Thanks *a lot*! This is brilliant! I tried it, and it works perfectly. There are issues for the test suite though, related to missing permissions for ccache. I'll post details later.

I see that you removed the -O3. Actually, the style used to implement Vcsn is very demanding on the compiler to get rid of the abstraction penalty, and -O3 is related needed to get the expected performances.

(EDIT: and now I see that -O3 is still there, together with -DNDEBUG, which is excellent... Sorry for not paying attention...)

Thanks again! It's great news!

Hi!

Vcsn 2.2 was released.

I attached the updated Portfile, and the diff.

Cheers!
