[openvsp] Segmentation falut export STEP file in OpenVSP

[jrparks9469]

Description When I attempt to export a STEP file, I receive a segmentation fault error regardless of the geometry. This happens both for trimmed and untrimmed STEP files.

Notes It doesn't happen for IGES files, which leads me to believe the error is related stepcode bundled with openvsp. The error doesn't occur when I compile from source on a debian based distribution. Might be able to resolve the problem by building stepcode from source and changing the cmake variables to use that installation rather than the bundled libraries, but I haven't been able to try that.

@jrparks9469 you could try using the system wide stepcode library by setting the -DUSE_SYSTEM_STEPCODE=true in the PKGBUILD however you might encounter some further errors with ambigous definitions of real.

I resolved the issue by building OpenVSP using the following method

# Create directories
mkdir OpenVSP
cd OpenVSP
mkdir repo build buildlibs

# clone repository
git clone https://github.com/OpenVSP/OpenVSP.git

# CMake libraries in Release mode
cd buildlibs
cmake -DCMAKE_BUILD_TYPE=Release \
-DVSP_USE_SYSTEM_CPPTEST=true \
-DVSP_USE_SYSTEM_LIBXML2=true \
-DVSP_USE_SYSTEM_EIGEN=true \
-DVSP_USE_SYSTEM_FLTK=true \
-DVSP_USE_SYSTEM_GLM=true \
-DVSP_USE_SYSTEM_GLEW=true \
-DVSP_USE_SYSTEM_CMINPACK=true \
-DVSP_USE_SYSTEM_CODEELI=true \
-DVSP_USE_SYSTEM_LIBIGES=false \
../repo/Libraries

make -j8

# CMake VSP in Release mode
cd ../build
cmake ../repo/src/ -DVSP_LIBRARY_PATH=/path/to/OpenVSP/buildlibs \
-DCMAKE_BUILD_TYPE=Release \
-DPYTHON_EXECUTABLE=/usr/bin/python

make

make package

I'm not familiar enough with PKGBUILD syntax (though it's probably something I should learn) to figure out how that differs from the method you're using. I didn't need the stepcode library after all.

Hopefully this is helpful

Glad you got it figured out, let's keep the issue open until the fixes are propagated into the package.

@jrparks9469 I went ahead and updated the pkgbuild with the same build process used for debian based systems. I believe the issue is fixed and I'll close the thread, but if you could test and comment on it that would be great.
