CMake configuration failures (Linux/gcc)

The cmake configuration phases of both the main repository and example/ap203min fail on Linux/gcc (Fedora 32) in the current master branch (2021-01-09), but there are easy fixes/workarounds.

Main configuration: Multiply defined symbols: ALG_fl, FUNC_fl, RULE_fl, PROC_fl, and WHERE_fl seem to be defined both in src/express/alg.c and src/express/memory.c causing a linking error during cmake configuration. Workaround/probable fix: change the declarations in alg.c to be extern

example/ap203min: cmake fails trying to read include/sc_cf.h.in Workaround: make a symbolic link at example/ap203min/include that points at ../../include
Probable fix: in the configure_file() call in cmake/SC_Config_Headers.cmake the ${CMAKE_SOURCE_DIR} should probably be ${SC_SOURCE_DIR}

Fix example build (Issue #404) by adding the sc_cf.h.in file (making …

Can you tell me which version of GCC you're using? On Ubuntu I'm not seeing the issue with alg.c vs. memory.c, and since only alg.c in master has ALG_fl I'm not quite sure where memory.c is pulling the definition from.

I think the above commit should handle the example - thanks for catching that. Looking at that, I should probably look at making that example work with an installed stepcode rather than depending on the stepcode build dir...

This is an issue with gcc-10, see e.g. https://gcc.gnu.org/gcc-10/porting_to.html, likely the default to -fno-common. Adding extern in alg.c seems to do the job.

$ gcc --version

I did a fresh clone of the repo, and my HEAD is now on your fix commit. I get that same error:

looking at the error logs file, strangely, I got other/more errors:
