We need more context. The lines you're quoting are just the tools
reporting that there was a problem. You've excluded the message about
the actual compile error. Running make without the -j option will
probably make it easier to see which part of the log message that
contains the interesting information. You might also want to add
'showcommnads' to you make command to have it echo the exact commands
run for each rule.

Are you in aosp-master branch?

We should use prebuilt gcc in prebuilts/tools/gcc-sdk (which is just a wrapper around some gcc in prebuilts/gcc/linux-86/host) now, 

while your error arose from pthread.h on your host machine /usr/include/pthread.h.

That shouldn't happen unless you don't have prebuilts/tools/gcc-sdk or  prebuilts/gcc/linux-86/host in your source tree.

Hi I tried to build aosp and aokp. Both fail with compile errors.
Here are the outputs:
aokp build: http://pastebin.com/WVkrmJBt

aosp build: http://pastebin.com/jPS0NNGm

If someone could tell me what I am doing wrong, I would be most grateful.
I did follow all instructions and did a lot of reading.
Thanks,

Add "showcommands" to your make command line, so we can look at the gcc command line for the broken file.

Also make sure you have prebuilts/tools/gcc-sdk and  prebuilts/gcc/linux-86/host in your source tree.

Hi yes I am in the master branch I initialised like this

repo init -u https://android.googlesource.com/mirror/manifest --mirror
repo sync
I mirrored the code and then setup a master like this


repo init -u /home/robert/aosp/mirror/platform/manifest.git
repo sync
 
I have even tried installing ubuntu 10.04 but the build fails under that as well.
I have now tried ubuntu 13.04 12.10 12.04 10.04. Build fails under all of them.

For the error message:

How could a target device source file end up including pthread.h on your host machine?

I double-checked there is no problem with the gcc command in your build log.

You can run the same gcc command with "-v" added to see the detailed header search path.

Most likely you have some environment variables set that affect the header file search path.

"man cpp" shows that "CPATH", "C_INCLUDE_PATH", "CPLUS_INCLUDE_PATH" etc are such variables.

Indeed, when I set "CPATH=/usr/include" I got the same error as yours.

Make sure to unset these variables before building Android.

Hi Sorry for providing too little output. I realized showcommands is a modifier.
I checked prebuilts/tools/gcc-sdk and prebuilts/gcc/linux-x86/host
both are there in the source build.

I hope all relevant information is in the output.
I downloaded the source a second time for testing but the build errors remain the same.
Thanks for your replies and patience.
