Errors in compiling Octave 4.2.0

[Cui, Shengting]

Hi,

I recently tried to install Octave 4.2.0 using intel compiler intel/xe_2016_update3 on a linux computer. My configuration line was:

./configure --prefix=/data/kamiak/shengting.cui/SourceCodes/octave-4.2-install --with-blas="-lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread" --with-lapack="-lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread" --with-fftw3="-lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm" --with-fftw3f="-lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm" CC=icc CXX=icpc F77=ifort --enable-fortran-calling-convention=f2c CFLAGS="-O3 -ipo -xAVX -fPIC -DMKL_LP64 -DM_PI=3.1415926535897932384" CPPFLAGS="-I$MKLROOT/include -I$MKLROOT/include/fftw" LDFLAGS="-L$MKLROOT/lib/intel64 -L$MKLROOT/../compiler/lib/intel64" JAVA_HOME=/opt/apps/java/oracle_1.8.0_92/

The MKLROOT variable was exported. The configuration went ok. But the compiling step failed at linking stage, giving the following errors:

icpc: command line warning #10006: ignoring unknown option '-Wold-style-cast'

icpc: command line warning #10006: ignoring unknown option '-Wcast-align'

liboctave/.libs/liboctave.so: undefined reference to `__builtin_add_overflow'

liboctave/.libs/liboctave.so: undefined reference to `__builtin_mul_overflow'

liboctave/.libs/liboctave.so: undefined reference to `__builtin_sub_overflow'

make[2]: *** [src/octave-cli] Error 1

make[2]: Leaving directory `/data/kamiak/shengting.cui/SourceCodes/octave-4.2.0'

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/data/kamiak/shengting.cui/SourceCodes/octave-4.2.0'

make: *** [all] Error 2

I searched on the internet and there are people seem to suggest that Intel compiler does not support `__builtin_add_overflow', `__builtin_mul_overflow', and `__builtin_sub_overflow' functions. Do you know if this is a fact? If yes, is there a way to get around it?

Thank you very much in advance for your help.
