Some notes on building talos-op-build.

NB: A complete build takes quite a lot of time and space. On my AmigaOne X5000 (dual core e5500 @ 2GHz) the build took about 15 hours. The final size of the build tree was 18 GB.

Required packages on gentoo

When building on gentoo, the following packages need to be installed: 

dev-perl/XML-Simple
dev-perl/XML-LibXML
dev-util/cscope
dev-util/ctags
dev-libs/expat
dev-libs/libxslt
sys-libs/zlib[static-libs]
sys-devel/bc

host-libopenssl-1.0.2m builds in 32-bit mode

If a compilation error complaining about the lack of <gnu/stubs-32.h> appears, this is because the libopenssl package is trying to compile in 32-bit mode and no 32-bit CRT is installed.

To fix, set the environment variable KERNEL_BITS to force a 64-bit build: 

export KERNEL_BITS=64
rm -rf output/build/host-libopenssl-1.0.2m
op-build

FTBFS in hcode

Compiling the current master of hcode (e45e1293f43a534fc180133ec588733035cd2dc8), the following fatal error is generated: 

../../import/chips/p9/procedures/ppe/tools/ppetracepp//ppetracepp.C: In function
 ‘int main(int, char**)’:

                                    ^

FTBFS in host-squashfs

There is a missing #include directive in the squashfs sources used, which leads to compilation errors such as these: 

mksquashfs.c: In function ‘create_inode’:
mksquashfs.c:991:24: error: called object ‘major’ is not a function or function 
pointer
   unsigned int major = major(buf->st_rdev);

sbe fails to build with python 3

This package uses the command "python" to launch scripts containing legacy constructs which are only valid Python 2, not Python 3. Thus, if "python" invokes a Python 3 interpreter they will fail. To fix, place the following patch in openpower/package/sbe/python.patch:
