Verilator "make test" systemc library path was "linux" instead of "linux64"

Hi,

I've just compiled Verilator successfully, but the test scripts had a small problem picking up the right directory that systemc's libraries are.

My systemc version is 2.2.0 and verilator is 3.702. I'm running Ubunutu 9.04.

In test_sc, the generated (I presume) file Vtop.mk, under obj_dir, was getting generated with VM_SC_TARGET_ARCH = linux, which it uses to determine the systemc library directory.

The error was this:

make²: Entering directory `/home/orsoc1/Documents/julius/scratch/verilator-3.702/test_sc/obj_dir' make²: *** No rule to make target `/usr/share/systemc-2.2.0/lib-linux/libsystemc.a', needed by `simx'. Stop.

My systemc install directory didn't have lib-linux, but rather lib-linux64.

The simple solution was symlinking lib-linux64 to lib-linux - that made all tests for verilator pass.

I wasn't sure how to alter the generated VM_SC_TARGET_ARCH variable so that it was linux64 as opposed to linux, so I'm posting this message. Perhaps someone can tell me which is the best solution - a simple symlink in my systemc path, or should something else be changed when calling verilator?

Thanks,

Julius

VM_SC_TARGET_ARCH comes from the SYSTEMC_ARCH environment variable, which probably isn't set right.

setenv SYSTEMC_ARCH=linux64 then ./configure and remake verilator.

Thanks.

SYSTEMC_ARCH must be set to linux64 when doing the make, most of all, I found.

Cheers,

Hello,

In installing Verilator I encountered this error, what's the problem?

I don't think this is related to the previous question, but run verilator with --debug. I suspect it's crashing for some reason, sorry usually it prints a better error. If you don't get an obvious message, also try --debug --gdbbt, and send the results.
