gzip error: unspecified iostream_category error

[david-hoze]

Hi, great work guys! I'm actually using one of your forks (https://github.com/dec1/Boost-for-Android), and getting this error:

gzip error: unspecified iostream_category error

I'm guessing this is because Boost is not being compiled with zlib. I know that zlib is natively supported in Android NDK, so I tried to add it to the ./b2 command (this is the command my fork uses, instead of ./bjam like you use) like so:

    run ./b2 -d+2 -q -j$NUM_JOBS \
        variant=release \
        ...
        ...
	-sZLIB_INCLUDE=$ANDROID_NDK_ROOT/sysroot/usr/include \
	-sZLIB_LIBPATH=$ANDROID_NDK_ROOT/sysroot/usr/lib/$TCPREFIX \
        install \

It does not work, and I'm even getting zlib: no in the build output. Have you had any experience with compiling Boost with zlib for android? If so, can you guide as to how to accomplish that?

Thanks in advance.

I was dealing with support for zlib in equalitie/Boost-for-Android fork of this project, in this 67ed5c6e86 commit in particular. Unfortunately I had been lazy to push it to the upstream. You could try to cherry pick that commit. If it works for you, it would be awesome if you could create a PR.

zlib is detected properly with NDK r19, libboost_iostreams library links to zlib. NDK r19 has built-in standalone toolchain, which makes all things much simpler.

Thanks, working with NDK r19 :+1:
