Hi,
I've got a few problems with Android, hopefully someone can give me some
pointers. I've not done a huge amount of cross-compiling for android, but
have built a few things successfully (libcurl with openSSL & C-ARES). Any
help/pointers appreciated, cheers.
*tl;dr summary*
I can't get libuv compiled using gyp, and I can compile libuv using
autotools, but make check fails and my test program doesn't function
correctly if I use this binary.
*Long version*
I've been doing a bit of prototyping using libuv & libcurl. Thus far, I
have my test program successfully running on iOS and I'm satisfied with it.
I'm now trying to get it running on Android. I've run into problems, though.
*Development environment*
Firstly, my development / compile machine's env:
Mac mini, x86_64, OS X Yosemite 10.10.2
Android NDK r10d, with native platform version=9
*Gyp:*
if I try to go the documented route and use gyp, the make stage fails.

The only modification I've made to the android-configure script is adding
--stl=gnustil, and this is just so that the toolchain mirrors what I've
used to build my other android libs. I've already cross-compiled libcurl &
its dependencies and that's working fine.

After a brief chat on IRC, tjfontaine said it looks like gyp is getting
confused and mixing in compile flags that aren't meant for this type of
cross-compile. He also suggested that gyp sometimes struggles with
cross-compile scenarios, and it would probably be a good bet to go the
autotools route. Given that I know absolutely nothing about gyp, I went
down the autotools route next.
*Autotools:*
When I go the autotools route, make runs without error, but make check
fails and my test program doesn't function correctly.

*$ make check*
lots of warnings like:
test/task.h:80:13: warning: anonymous variadic macros were introduced in
C99 [-Wvariadic-macros] (should I be specifying C99 somewhere?)
then...
*test/test-signal-multiple-loops.c:248: error: undefined reference to
'uv__pthread_sigmask'*
collect2: error: ld returned 1 exit status
make[1]: *** [test/run-tests] Error 1
make: *** [check-am] Error 2
So basically, I'm a bit stumped now. Hopefully I'm just making some sort of
newbie CC error. Any help appreciated.
