Before releasing ADMB-IDE, we try to make sure that all components work
smoothly together. The lag between the last IDE release and more recent
versions of ADMB is mainly due to a new generation of user compilation
scripts (where safe compilation will be the default) that are taking shape
Like you, we have seen strange error messages with some GCC distributions.
Based on extensive tests last summer, our conclusion is the same as yours:
to make life easier for everyone, we intend to release the next ADMB-IDE
with the GCC compiler that comes with Rtools, and recommend that for
building ADMB from sources.
Building ADMB from sources on Windows has always been a challenge and
continues to be so. As you point out, it's a complex interplay between
installing programs like GCC and make, disabling PATH directories that
might interfere (sometimes sh.exe must be excluded), testing what works to
build ADMB, and finally updating the documentation (in several places,
It's a topic almost worth its own mailing list, but
developers at admb-project.org is probably better than users at . Anyone can
subscribe to developers@ and the discussion is readable and searchable on
Lately, this aspect of ADMB development has mainly involved Johnoel
Ancheta making changes to the makefile tree, while Chris Grandin and I try
building with different setups. This process can be time-consuming and
give strange results, so if you can lend a hand and test whether Rtools
can build ADMB that would be excellent.
All the best,
