Some notes on building talos-op-build
Contents
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
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**)’: ../../import/chips/p9/procedures/ppe/tools/ppetracepp//ppetracepp.C:1097:36: err or: ignoring return value of ‘char* fgets(char*, int, FILE*)’, declared with att ribute warn_unused_result [-Werror=unused-result] fgets(buf, MAX_BUFFER, PWD); ^ cc1plus: all warnings being treated as errors
To fix, place the following patch in openpower/package/hcode/fgets.patch:

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:
