Add port for liblightgrep

[jessekornblum@…]

liblightgrep is a library for searching data using regular expressions as defined in Unicode Technical Standard #18. There are lots of details, including a handy cheat sheet, at the project's homepage, ​http://www.lightboxtechnologies.com/lightgrep-engine.

I am willing to be the maintainer of this port.

First thing I notice: you should probably be using compiler.blacklist and compiler.whitelist instead of manually setting CC and CXX in the build environment.

Can you please point me to the documentation for specifying the compiler to use? I'm having trouble finding it. The library requires gcc 4.6 or later. How do I force the configure command to use the latest version of gcc/g++ above 4.6?

thanks!

Replying to jessekornblum@…:

There… uh… really isn’t any. There are a couple of wiki pages:

• PortfileRecipes#compiler
• UsingTheRightCompiler

The recipe is outdated; MacPorts 2.2 automatically adds the necessary dependencies for compilers.

The library requires gcc 4.6 or later. How do I force the configure command to use the latest version of gcc/g++ above 4.6?

Remove the build dependency on port:gcc48 and add this:

compiler.whitelist  macports-gcc-4.8 \
                    macports-gcc-4.7 \
                    macports-gcc-4.6

configure.args      CC=${configure.cc} \
                    CXX=${configure.cxx}

Also disable the universal variant, since you’re using FSF GCC:

universal_variant   no

(Unless you feel like adding the muniversal-1.0 PortGroup and hacking together a universal build manually.)
