One of our Ubuntu 16.04 systems (gcc 5.4.0) is failing a compilation that previously succeeded. The failure is:
$ g++ -c -std=c++14 -Wall -pedantic -m64 -march=native -I../Kernel -I/net/simdata/Hudson_OpenSourceLibs/Boost/ -fpic -O3
../StarLibs/StdStars/ArithmeticCoding.cpp -o _gnuRelease/ArithmeticCoding.o
cc1plus: fatal error:
/net/simdata/Hudson_OpenSourceLibs/Boost/stdc-predef.h: Input/output error
compilation terminated.
If I exclude the -I/net/simdata ... (which is a mounted drive) the compilation succeeds without failure.
For the failure case, the search order is:
ignoring duplicate directory "/usr/include/x86_64-linux-gnu/c++/5"
ignoring nonexistent directory "/usr/local/include/x86_64-linux-gnu"
ignoring nonexistent directory
"/usr/lib/gcc/x86_64-linux-gnu/5/../../../../x86_64-linux-gnu/include"

End of search list.
(shown by adding -v to the gcc command).
The include file in question is not on the mounted drive but is found (as expected) at:
$ ls /usr/include/stdc-predef.h
/usr/include/stdc-predef.h
The mount seems to be working ok:
$ ls /net/simdata/Hudson_OpenSourceLibs/Boost/rel-1.69.0/boost/
accumulators dll.hpp make_unique.hpp random.hpp
align dynamic_bitset math range
etc.
I don't understand why gcc is reporting an i/o failure for the mounted drive and is failing to find the include file in /usr/include.
Can anyone help please?
