Use of gzip about bh

[eddelbuettel]

I can take a look but note first that you do not need Boost to open gzip'ed file. R already does it via all of read.table() and variants, and you can also do it in plain C/C++ code via gzopen() -- which should also "just work" because R is always built wiith that library.

As for "I can solve it this" that is indeed correct, but your package now becomes less portable as all users would have to have these libraries available "and visible". Unlikely on Windows. In short, this is the difference between using Boost as header-only (as BH) or using Boost full-fledged with linking. Some libraries and components only work in the latter way. It is up to you balance those costs and benefits.

I didn't know about gzopen(). I'm going to change my code in order to use it. Thank you. Please let me know if you find the reason of the error.

Yes, gzopen() is gold. Been using it for decades (!!).

I told you the error. The way Boost implements this requires linking with Boost.
