Error running make at top level

I get the following error when running make at the top level of zipcpu.

This is looking similar to this problem. Can you please run cygcheck -s -v -r > cygout.txt and include that as an attachment as well?

Thanks!

@rpflaum2000 , Initial testing suggests the problem might be parallel compilation. Try a "make clean", and then a "make -j1". (You may need to go back and rebuild the compiler and verilator with -j1 as well) Dan

I will try the -j option with make a little later this evening. I have to go a take care of some other family business first. Bob

[rpflaum2000]

I performed a make clean in the top level verilator directory. I then ran make -j1. Build successful. I then performed a make clean in the top level zipcpu directory followed by a make -j1. The build was unsuccessful with the same errors as reported initially above. I am at work now but I will continue to investigate more this evening upon arrival at home.

Ok, I managed to reproduce the problem. The problem lies in /usr/local/share/verilated/include/verilatedos.h, where vluint64_t is defined as an unsigned long long. If you instead define it as an unsigned long, and likewise vlint64_t as a long, you'll get a lot of warnings, but the demo will build and compile.

However, this just doesn't seem like the "right" solution, so ... I'll keep digging a bit further, Dan

[ZipCPU]

Ok, I can fix this now ... by adding placing -D__WORDSIZE=64 to the compiler flags, this now builds and passes its tests for me on a Windows system. I'll have an update shortly, Dan

[ZipCPU]

Patch applied. Please do a "git pull", and then run "make clean; make" in first the rtl/ and then the sim/verilated directories. After that, everything should work as advertised--no changes to /usr/local/share/verilator/include/verilatedos.h required. Dan

[rpflaum2000]

I was able to complete the build per your instructions after pulling the patch. I have been able to run through your blog post "ZipCPU toolchain and initial test" successfully. I need to spend some time now to understand the details. Thanks for being so responsive on this.
