Some notes on building talos-op-build

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
sys-libs/zlib[static-libs]

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

Broken hcode reference

The Makefile for the hcode package (openpower/package/hcode/hcode.mk) specifies 37069e1756e2b8e70e8e185d28609414033dbc02 as the version to checkout. However, no such commit exists in the git repo (https://scm.raptorcs.com/scm/git/talos-hcode). Current master is at e45e1293f43a534fc180133ec588733035cd2dc8. Maybe Raptor forgot to push something?

As a workaround, change the value of HCODE_VERSION in the Makefile from 37069e1756e2b8e70e8e185d28609414033dbc02 to e45e1293f43a534fc180133ec588733035cd2dc8.

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

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:
