[Paraview-developers] SuperBuild on Linux: Numpy fails to build with "(.text+0xa): undefined reference to `MAIN__'"

[Peter Schmitt]

Hi,

I am building the ParaView SuperBuild on my Linux box.  The build fails
while building Numpy:


/usr/bin/gfortran -Wall
-L/hao/tyr1/schmitt/paraview/opt/ParaView-3.98.1-Linux-x86_64/install/lib

I found this same issue in the Numpy bug tracker:
http://projects.scipy.org/numpy/ticket/182  The fix on the Numpy bug
tracker: don't modify LDFLAGS prior to building Numpy.
 However, pv-numpy-build.cmake does modify LDFLAGS accordingly:

 LDFLAGS=-L/hao/tyr1/schmitt/paraview/opt/ParaView-3.98.1-Linux-x86_64/install/lib

Any idea of what I should do?

System details:
