Hi guys- I'm still working on that other issue with winbind, but trying to get a scratch build completed from source in my environment to test the latest version. I've seen someone else run into this before as well, but I'm not entirely sure what the resolution was. Anyone remember this error: Checking for 'xlc' (C compiler) : Traceback (most recent call last): File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Utils.py", line 828, in wrap return cache[k] KeyError: (<samba_waf18.ConfigurationContext object at 0xb050ec2c>,) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Utils.py", line 828, in wrap return cache[k] KeyError: (<samba_waf18.ConfigurationContext object at 0xb050ec2c>,) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Scripting.py", line 159, in waf_entry_point run_commands() File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Scripting.py", line 255, in run_commands ctx = run_command(cmd_name) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Scripting.py", line 239, in run_command ctx.execute() File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Configure.py", line 159, in execute super(ConfigurationContext, self).execute() File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Context.py", line 204, in execute self.recurse([os.path.dirname(g_module.root_path)]) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Context.py", line 286, in recurse user_function(self) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/wscript", line 141, in configure conf.RECURSE('lib/replace') File "./buildtools/wafsamba/samba_utils.py", line 66, in fun return f(*k, **kw) File "./buildtools/wafsamba/samba_utils.py", line 463, in RECURSE return ctx.recurse(relpath) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Context.py", line 286, in recurse user_function(self) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Utils.py", line 830, in wrap ret = fun(*k) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/lib/replace/wscript", line 30, in configure conf.RECURSE('buildtools/wafsamba') File "./buildtools/wafsamba/samba_utils.py", line 66, in fun return f(*k, **kw) File "./buildtools/wafsamba/samba_utils.py", line 463, in RECURSE return ctx.recurse(relpath) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Context.py", line 286, in recurse user_function(self) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Utils.py", line 830, in wrap ret = fun(*k) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/buildtools/wafsamba/wscript", line 243, in configure conf.load('compiler_c') File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Configure.py", line 271, in load func(self) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Tools/compiler_c.py", line 79, in configure conf.load(compiler) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Configure.py", line 271, in load func(self) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Tools/xlc.py", line 59, in configure conf.find_xlc() File "./buildtools/wafsamba/samba_utils.py", line 66, in fun return f(*k, **kw) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Tools/xlc.py", line 17, in find_xlc conf.get_xlc_version(cc) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Configure.py", line 317, in fun return f(*k, **kw) File "/opt/freeware/src/packages/BUILD/samba-4.12.15/third_party/waf/waflib/Tools/c_config.py", line 1097, in get_xlc_version cmd = cc + ['-qversion'] TypeError: unsupported operand type(s) for +: 'NoneType' and 'list' error: Bad exit status from /var/tmp/rpm-tmp.S3Uaab (%build) I'm trying to build it as an RPM, but that shouldn't matter... the error stack comes from the actual sources...
