Multiple errors during compilation

[ooptimum]

I'm just about to start using this library. For tests, I created a simple project and included the cgbn.h header file. While compiling I got an error saying that I should use gmp for now. This error happened due to the non-matching condition on line 67 of the cgbn.h file, because macro __CUDA_ARCH__ is not defined in code running on the host. So I was forced to declare macro __CUDA_ARCH__ explicitly before including the header file.

After that, the compilation progressed further, but I immediately got a few errors about undefined identifiers. Two of them are in padded_resolver.cu and one is in core_counting.cu.

I believe that line 250 of padded_resolver.сu should be read as uint32_t g, p, lor;, and line 266 as lor=mplor<LIMBS>(x);. But I'm not completely sure, because I have not yet understood the logic of the code and my assumption is based only on a guess that the code should look like this so that the error disappears. As for the core_counting.cu, on line 93 there is an undefined variable topctz. Perhaps the bottomctz variable should be returned instead?

However, the fact that test applications compile and run without errors makes me doubt that maybe I'm doing something wrong, since I immediately encountered the described errors? Am I missing something essential which should be done apart of just including the header file?

My environment is: Ubuntu 21.10, Cuda compilation tools 11.6.

There is also a typo in the CONSTANT_TIME symbol in line 107 of cgbn_kuda.h. Now it's CONSANT_TIME.

I also met the issue, and more errors occurred.:
`./include/cgbn/core/padded_resolver.cu(266): error: identifier "lor" is undefined
lor=mplor(x);
^

./include/cgbn/core/padded_resolver.cu(266): error: identifier "limbs" is undefined
lor=mplor(x);
^

./include/cgbn/core/core_counting.cu(93): error: identifier "topctz" is undefined
return umin(topctz, TPI);
^`
I think these are just typos, but I'm not sure why they were not corrected during testing.
