[Octave-bug-tracker] [bug #41699] imformats causes a segmentation fault on Windows when Octave exits

[Rik]

Follow-up Comment #69, bug #41699 (project octave):

@Mike: The problem seems to be the test compilation program which does
#include <omp.h>.


configure:12529: checking for OpenMP flag of C compiler
configure:12571: i686-w64-mingw32-gcc -o conftest.exe -g -O2 -pthread -fopenmp

Does this mean that the host machine needs omp.h installed?  I did find omp.h
on my host system.

The cross compiler environment in MXE alread seems to have omp.h installed.


find . -name 'omp.h'
./usr/home/rik/wip/Projects_Mine/mxe-octave/usr/i686-w64-mingw32/lib/gcc/i686-w64-mingw32/4.9.2/include/omp.h
./usr/i686-w64-mingw32/lib/gcc/i686-w64-mingw32/4.9.2/include/omp.h


Maybe the -I flags are not getting set correctly for cross-compilation of
configure test files.
