Gcc version is too low in devcloud

[Weihao]

Hello,

I'm using the FPGA DevCloud, more specifically, the Arria 10 PAC Compilation and Programming with Development Stack 1.2. I use this command to run the aocx file on the hardware:

env PRAGMAUNROLL=1 BITSTREAM=./lu.aocx AOC_OPTION="-v -fpc -fp-relaxed -fmax=500 -board=pac_a10" ./lu.out

But I got this error:

/lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by ./lu.out)

I check the gcc version of this node, and it turns out the gcc version is only 5.4. 

Is this error caused by low gcc version? Can devcloud update the gcc? (For example, I may used newer g++ to compile llvm)

Thanks,

Weihao
