My host system has an x-86_64 architecture with ubuntu-18.04 running on
top of it, I have a python2 installed.
Interestingly enough, when I clean up the libbsd directory and try to build
as a super-user, I have two observations:-
1. The build fails with the following error message:-
[1/4] Creating
///h/o/m/e///u/r/1/0///s/a/n/d/b/o/x///r/t/e/m/s/-/l/i/b/b/s/d///b/u/i/l/d///a/r/m/-/r/t/e/m/s/5/-/b/e/a/g/l/e/b/o/n/e/b/l/a/c/k/-/d/e/f/a/u/l/t/build-include/rtems/bsd/modules.h
[2/4] Compiling rtemsbsd/rtems/generate_kvm_symbols
[3/4] Compiling testsuite/include/rtems/bsd/test/network-config.h.in
/bin/sh: 1:
.//home/ur10/sandbox/rtems-libbsd/rtemsbsd/rtems/generate_kvm_symbols: not
found
Now I have checked, and the file in question is present at its location.
2. The traceback of the last calls is something like this:-
File
"/home/ur10/sandbox/rtems-libbsd/.waf-2.0.13-4c5a17779813574907c253ab5418388d/waflib/Build.py",
line 100, in execute_build

line 153, in store

File

line 155, in writef
with open(fname,m)as f:
IOError: [Errno 2] No such file or directory:
u'/home/ur10/sandbox/rtems-libbsd/build/arm-rtems5-beagleboneblack-default/.wafpickle-linux2-34017264-20.tmp'
If I am correct, this is a python exception for invalid file handling.
Since I have already removed the 'build' directory, I suppose the call
should be 'w+' or 'wb+' but this does not seem to be the case. (I am going
out on a limb with this assumption, I may be wrong !)
It would be very helpful if you could provide your views on the problem and
as to how I should proceed to resolve this.
