Hi,

To investigate further my issue, I ran all iostream unit tests on Android, and found 5 tests to fail (even though there seem to be a duplicate). Other tests, including "gzip_test", are okay. Results follow.

I'm willing to help & debug, but I have now clue about where to start from. Anyone has one (clue, of course)? Thanks.

Objet: Boost.iostreams on Android - Fails on multichar input filters

Hi,

I found iostreams "filtering_stream_test" to fail under Android (32 bits, gcc 4.6, boost 1.52.0) :
"
Running 18 test cases...
read_input_filter_test.hpp(88): error in "read_input_filter_test": failed reading from a filtering_istream in chars with a multichar input filter
read_input_filter_test.hpp(101): error in "read_input_filter_test": failed reading from a filtering_istream in chunks with a multichar input filter
"

Note : I ran some tests by compiling on the host machine (64-bits Linux), then manually copying/running on the (emulator) device (using "adb push" / "adb shell").

I know Android is not actively maintained, but I need multichar filters (gzip_compressor & gzip_decompressor are multichar and thus fail). And I wonder why this test fails.
I could not run the regression test on iOS, but my original code (using gzip_decompressor) works as expected under iOS, and Windows, and MacOSX.

I have no clue about how to solve the issue. Any idea?

Thank you.
Cheers,

Sukender
