> Are you using an Nvidia graphic card?

no nvidia involved in my case:
I'm running a Lonovo X260 with Intel Corporation Skylake GT2 [HD Graphics 520]


it's a bug in libopencsg.so.1 (libopencsg1-1.4.2-1.14.x86_64) 
which is linked against ibGLEW.so.2.2 but requires sybbols from ibGLEW.so.2.1
as you can see here:


actually those unresolved symbols come from /lib64/libopencsg.so.1,
7 out of 10 missing routines have "SGIX" in their name:

$ ldd -r /lib64/libopencsg.so.1 | grep undefined 
undefined symbol: __glewXGetFBConfigAttribSGIX  (/lib64/libopencsg.so.1)
undefined symbol: __glewXChooseFBConfigSGIX     (/lib64/libopencsg.so.1)
undefined symbol: __GLXEW_SGIX_fbconfig (/lib64/libopencsg.so.1)
undefined symbol: __glewXDestroyGLXPbufferSGIX  (/lib64/libopencsg.so.1)
undefined symbol: __glewXGetCurrentDisplay      (/lib64/libopencsg.so.1)
undefined symbol: __GLXEW_SGIX_pbuffer  (/lib64/libopencsg.so.1)
undefined symbol: __GLXEW_NV_float_buffer       (/lib64/libopencsg.so.1)
undefined symbol: __glewXCreateGLXPbufferSGIX   (/lib64/libopencsg.so.1)
undefined symbol: __glewXGetVisualFromFBConfig  (/lib64/libopencsg.so.1)
undefined symbol: __glewXCreateContextWithConfigSGIX   
(/lib64/libopencsg.so.1)

$ ldd -r /lib64/libopencsg.so.1 | grep undefined | grep -c SGIX
7

looking for some of the missing syms they can be found from libGLEW.so.1.* up
to libGLEW.so.2.1 -- but no longer in libGLEW.so.2.2 which libopencsg.so.1 is
linkged against:

$ ldd -r /lib64/libopencsg.so.1 | grep undefined | grep -c -v SGIX
3grep -l __glewXChooseFBConfigSGIX  /usr/lib64/libGLEW* 
/usr/lib64/libGLEW.so.1.13
/usr/lib64/libGLEW.so.1.13.0
/usr/lib64/libGLEW.so.2.0
/usr/lib64/libGLEW.so.2.0.0
/usr/lib64/libGLEW.so.2.1
/usr/lib64/libGLEW.so.2.1.0
/usr/lib64/libGLEWmx.so.1.13
/usr/lib64/libGLEWmx.so.1.13.0

$ ldd -r /lib64/libopencsg.so.1 | grep GLEW
        libGLEW.so.2.2 => /lib64/libGLEW.so.2.2 (0x00007f65b7147000)

$ nm -D /lib64/libGLEW.so.2.1  | grep -c __glewX
115

$ nm -D /lib64/libGLEW.so.2.2  | grep -c __glewX
0



so I tried preloading an older libGLEW which provides those missing symbols,
and guess what -- openscad starts and seems to work:

LD_PRELOAD=/lib64/libGLEW.so.2.1 openscad rc1.scad


BUT when quitting openscad there is a SIGSEGV:

$ LD_PRELOAD=/lib64/libGLEW.so.2.1 openscad rc1.scad
Segmentation fault (core dumped)
