IBEX Compiling issue

[rswarbrick]

This is an error building the Spike code (a dependency that we don't maintain). It looks like you've got a recent version of upstream's Spike: that code was added in June this year.

To get things working, you'll need the version of spike that we describe in the documentation.

Hi Mr.Rupert Swarbrick,

I downloaded exact spike version "riscv-isa-sim-ibex-cosim-v0.5.tar.gz" and configure with --enable-commitlog --enable-misaligned option, then when we run "make IBEX_CONFIG=opentitan SIMULATOR=vcs ISS=spike ITERATIONS=1 SEED=1 TEST=riscv_arithmetic_basic_test WAVES=0 COV=0 VERBOSE=1"

am getting following error
/opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: cannot find -lriscv \

/opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: cannot find -lsoftfloat \

/opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: cannot find -ldisasm \

/opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: cannot find -lfdt \

When we checked the spike installation location we got .a file and not getting .so file, I pasted the files detail as below
lib]$ ls
libcustomext.so libfdt.a libriscv.a pkgconfig
libdisasm.a libfesvr.a libsoftfloat.so

phkconfig folder having:
riscv-disasm.pc riscv-fdt.pc riscv-fesvr.pc riscv-riscv.pc

Any suggestion on this please?

That file list looks sensible to me. I suspect that the build command isn't passing the right -L flags to the linker. Maybe it's worth you looking at the ld command that actually ran. I think we pick up those flags from pkgconfig, so you might find you need to check that you have set up PKG_CONFIG_PATH to something sensible.

Hi Mr.Rupert Swarbrick,

**if we run make without PFG_CONFIG_PATH, am getting below error**

Traceback (most recent call last):
File "scripts/compile_tb.py", line 75, in _main
subprocess.check_output(['pkg-config', '--exists'] + spike_iss_pc)

subprocess.CalledProcessError: Command '['pkg-config', '--exists', 'riscv-riscv', 'riscv-disasm', 'riscv-fdt']' returned non-zero exit status 1.

The above exception was the direct cause of the following exception:

f'Did you set the PKG_CONFIG_PATH correctly?') from err
RuntimeError: Failed to find ['riscv-riscv', 'riscv-disasm', 'riscv-fdt'] pkg-config packages. Did you set the PKG_CONFIG_PATH correctly?

But if I set PKG_CONFIG_PATH, setenv PKG_CONFIG_PATH /Projects/marmik_project/manicka.vinodhini/krishna/spike-13.09.23/lib/pkgconfig. am getting error as below

OK, it looks like you have set PKG_CONFIG_PATH. You'll still need to look at the actual ld command to work out what's going wrong. This is also now a little beyond what you might expect as help from a GitHub issue conversation. :-) Good luck getting things working!

Hi Rupert Swarbrick,

 we installed ubuntu and installed spike and ibex , when we run "make IBEX_CONFIG=opentitan SIMULATOR=vcs ISS=spike ITERATIONS=1 SEED=1 TEST=riscv_arithmetic_basic_test WAVES=0 COV=0 VERBOSE=1"  am getting below error

Let me know which gcc version we need to use in ubuntu 22.04
