Fighting to install OpenVSP

[Joel Malissa]

Dear OpenVSP Pros,

For the past day or two, I have been fighting with a new Red Hat linux machine (RHEL6) to install VSP.  I had to install gcc 5.3.0 manually since my machine only came with gcc 4.4.7, and I'm not sure if this is part of the problem.  I've gotten past several stumbling blocks already, but now I seem to be stuck beyond my ability to google my way past this.  When I run sudo make, I get the output below.  Do you have any recommendations to move forward?

Thank you,
Joel

I'm sorry you've had such trouble. Don't be shy about asking.

I'm not sure exactly which gcc versions work and don't work. I
usually build on llvm/clang on MacOS.
When I have been building with gcc, I've been using a 4.8 version. If
you go too old, C++11 features start dropping off. However, I would
have guessed 4.4 would be OK. To my knowledge I haven't tried any gcc
5.X yet, I guess I need to catch up.

The good news is, that error message is at the very end of the
process. Everything has compiled, but it is having trouble when it
came to the final link steps. All the CMake configuration stuff
passed -- so it shouldn't have run into this problem. However, it
did, so we'll work on it.

From the look of the error, your gcc version isn't the problem.

OpenVSP bundles our own FLTK in the build, but on Linux it is
generally better to use the OS supplied version.

Did you pass -DVSP_USE_SYSTEM_FLTK=true to CMake when you did this build?

That is probably the easiest way to get around this problem.

Also, no need to use 'sudo' when building VSP. You generally only
want to use sudo when you're installing a program on Linux (final
step). Since VSP doesn't have a 'install' target in the build, you
probably don't want to use sudo at all for our stuff.
