libevent failed

[zshliao]

Hi I was following your instruction but it keeps failing when I tried to make install libevent (type.h was missing).. Is there any good instructions on how to install libevent? Also I'm wondering if you are willing to share the shrpx binary file?

[zshliao]

when I ran ./android-make i got following errors:

/home/zisheng/toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: error: http-parser/http_parser.o: incompatible target
/home/zisheng/toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: spdycat.o: in function spdylay::update_html_parser(spdylay::SpdySession_, spdylay::Request_, unsigned char const_, unsigned int, int):spdycat.cc:407: error: undefined reference to 'http_parser_parse_url'

It looks like http_parser.o was compiled targeted for unexpected architecture.
Please first run make clean and re-run ./android-make again.

Thank you so much for the reply now the compilation works.. But I did not see the shrpx binary under src folder, did i miss something there?

Iibevent may not be detected by configure script (./android-config for NDK).
Configuring libevent is very similar to spdylay since libevent uses autotools too. I think following would work for libevent:

$ ./configure
    --disable-shared \
    --host=arm-linux-androideabi \
    --prefix=$ANDROID_HOME/usr/local
    CPPFLAGS="-I$ANDROID_HOME/usr/local/include" \
    LDFLAGS="-L$ANDROID_HOME/usr/local/lib"

And build libevent:

$ PATH=$ANDROID_HOME/toolchain/bin:$PATH make

[zshliao]

Thanks for the reply..
I used your command to configure the build system for libevent however it does not recognize the siable-shared option
./libevent.sh: 4: ./libevent.sh: --disable-shared: not found
We are using the source from http://libevent.org/ libevent-2.0.21-stable
Any help on how to solve this issue would be greatly appreciated..
Thanks

Some formatting mistake in configure cmd line. It should be read as:

$ ./configure \
    --disable-shared \
    --host=arm-linux-androideabi \
    --prefix=$ANDROID_HOME/usr/local \
    CPPFLAGS="-I$ANDROID_HOME/usr/local/include" \
    LDFLAGS="-L$ANDROID_HOME/usr/local/lib"

[zshliao]

Awesome! Thank you so much for that now libevent is built and detected by ./android-config

but running ./android-make still gives one erorr:

/home/zisheng/toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: error: cannot find -lrt
collect2: ld returned 1 exit status

make: *** [all] Error 2

This is the summary of configuration:

Not sure what I missed at this point.

Thank you very much in advance.

We use android NDK r9d gcc 4.8 and it compiles spdylay fine. No error related to -lrt.
