ANTLR is a parser generator that targets many languages. Some languages, like C++, require a shared or static library to be present when linking the application using the generated files. If possible it seems these should be installed when dev-java/antlr is installed, potentially controlled by USE flags. Use of ANTLR regardless of target language requires Java and dev-java/antlr, at the very least to process the grammar. If they are installed, I was not able to find them. There exist dev-libs/antlr-c and dev-cpp/antlr-cpp - should this bug be a packaging or version update request instead?
Please be clearer. Have you actually tried antlr-c or antlr-cpp? The former certainly does install a shared library. The latter does but only for v2. With v3, there is no library. What version are you interested in? Old dev-java/antlr ebuilds for 2.7.7 used to deal with all the languages in a single ebuild. This made the ebuild hard to use and the code was a mess. I therefore split it up.

The extant packages have not been installed because they are versions I am not interested in.

As far as I can see, there are no C bindings for ANTLR 4. C++ bindings were introduced in 4.6. We currently only have 4.5.3 in the tree. Bug #605036 has been filed to get it bumped. dev-java/antlr is a particularly thorny package so I haven't rushed to bump this, especially as nothing in the tree currently requires the latest version. Java packaging in general has largely stalled. A pull request would be welcome.
Created attachment 541484 [details] antlr-cpp-4.7.1.ebuild This ebuild seems to work fine for me. This is going to be a dependency for mysql-workbench 8.x
