VL_VALUEPLUSARGS_IW should no longer be used; it's somewhat surprising the compiler is complaining, but I removed the old functions from verilated.cpp, please try the git head.

Hi Wilson

Thanks for a prompt update. I rebuilt Verilator from master after your latest commit. Now got another error:

../main.cpp: In function ‘int main(int, char**, char**)’:
../main.cpp:40:6: error: ‘VL_VALUEPLUSARGS_II’ was not declared in this scope
if (VL_VALUEPLUSARGS_II(32 ,"randseed=",'d', randomSeed))
^~~~~~~~~~~~~~~~~~~

../main.cpp:40:6: note: suggested alternative: ‘VL_VALUEPLUSARGS_INI’
if (VL_VALUEPLUSARGS_II(32 ,"randseed=",'d', randomSeed))

Compiler is GCC 7.1 under Ubuntu 14.04.5

NOTE:

This is NOT a compile error. I built Verilator seamlessly. I get this error when I compile my RTL and trying to run the simulation

I suspect you are verilating with one version of verilator, then compiling that output pointing at a different version's includes.

Hi Wilson

Wrong assumption. Do you want me to upload my Verilator build ?

I've been using Verilator for ages with the same Makefile and have no issues with verilator_3_902

There is no longer any occurrence of VL_VALUEPLUSARGS_IQ in the verilator sources, and the internal tests that use plusargs work. Therefore I am presuming there's something wrong in your setup, perhaps picking up an older version.

However perhaps I'm missing something, and if you can modify the test_regress/t/t_sys_plusargs.v to show the problem, I'll fix it.

Wilson, pls take a careful look at the error. It complains on VL_VALUEPLUSARGS_II, not VL_VALUEPLUSARGS_IQ.
I can't verilate my RTL with this error.

Your message said "main.o: In function `VL_VALUEPLUSARGS_IQ".

Regardless, please modify the test_regress/t/t_sys_plusargs.v to show the problem, and I'll fix it.

The first error from the ticket description has gone. I'm now talking about another issue, reported in #2.

Okay, will update the plusargs test and be right back soon. Thanks for support

I just built verilator_3_906-8-g13f7903. I ran standard tests and they all have passed.

GCC 7.1 complains on line 40 in the main.cpp attached. The issue is in the random seed initialization with the VL_VALUEPLUSARGS_II method.

Oh, so it's your code that's calling it, not verilator. That makes a lot more sense then. VL_ functions occasionally change, and while changes are avoided they do sometimes need to change, so if you're using them you'll need to keep up to date.

Use instead VL_VALUEPLUSARGS_INI(32, "randseed=%d", randomSeed);
