Error when make: syntax error while compiling "threadpool.cpp"

[chrisweird7]

I followed the instruction to generate the Makefile and succeeded.

While the make process, some error occurred while compiling the "threadpool.cpp", I think it's a syntax error.

I know almost nothing about c++, but I'm very interested in glass3, so please help.

The detailed error information are as follows:

What version of GCC are you using? Glass utilizes STL functions that require at least version 5.0.4 of the GNU C/C++ compilers or similar.

The GCC version on my computer is 10.3.0 i.e. "gcc (Ubuntu 10.3.0-1ubuntu1) 10.3.0"

In order to apply the glass3, I downloaded VMWare on my computer (Windows System) and build a virtual machine (Ubuntu 20.04). I installed gcc, g++ and so on by "apt install" instructions, so I think they are all up to date.

[jpatton-USGS]

In that case, I would install gcc 5.x, which is the current c++ compiler used by the NEIC

Thank you very much for the suggestions. I changed the gcc into 5.x version at last. Actually, it's a tough work for me. After dozens of attemps, I find Fedora 23 is more suitable for the compile environment, and successfully installed gcc 5.x.

Yes, now the problem is solved. But then another error struck me. I searched the Internet for relevant solutions but still failed to work it out. The error is as follows, I eager for some more suggestions to deal with it. Thank you again!

So, what you are encountering is an error in building the glass3 unit tests, which require the google test package to be installed. However, the unit tests are primarily useful when we are developing changes or fixes to the algorithm, and are not required for building the application or using it. You can disable the building of the unit tests by adding the option -DRUN_TESTS=0 to your cmake command.
