[BRLTTY] building brlapi for Android (ARM processor)

[Shiri Azenkot]

Hi Dave,

Not quite as simple for me. I got a Java exception when doing the make.


 What version of the jdk do you have? You need JDK 5.0; java 6 is not
supported.

Yes, the toolchain is prebuilt, but you'll need to build the bionic libc.
This is a modified libc for Android. I just built the whole source tree
since there were no instructions on how to built only bionic.

 Yes, I got this error at some point too. crt0.o is part of the C standard
libraries, so after you build bionic and include them properly in the build
this should hopefully go away.

tools. I changed it so now it uses the 4.4.0 tools. I'm getting the same
error, but at least now we're using the correct version.

It prints the cflags for building libraries with bionic and the Android
prebuilt toolchain. It includes a bunch of paths from the Android source
including the bionic libraries. When trying to build brltty, I executed the
following command:

$ CFLAGS=`./printcflags` ./configure --host arm-eabi


Hope this helps. Let me know what happens!
