Nv_small problem to build test bench #120

Open Y159753 opened 6 years ago

Y159753 commented 6 years ago

Hello, after following the build tree instructions for the Nv_small configuration I try to continue with the testbench build, but it doesn't work. Do you have an idea of the cause ?

leiwang2016 commented 6 years ago

@Y159753 are you using python 2 or python 3. You should be able to get rid of this error with python 3.

HKLee2040 commented 6 years ago

I got the same error message.

@leiwang2016 : So, do we need to use python3 instead of python2?

Environment setup shows following information The versions listed are used for testing. •Java - jdk1.7 •Perl - perl-5.10•XML::Simple •Capture::Tiny

•CPP - gcc-4.9.3 •Python - python2.6 •SystemC - systemc-2.3.0 •(for Verilator builds) Verilator - Verilator 3.912 •(for Verilator builds) clang - clang 3.4

leiwang2016 commented 6 years ago

@HKLee2040 python 2 string defaults to 8bits, which is fixed in python 3. if you look at environment setup guide for v2. http://nvdla.org/hw/v2/environment_setup_guide.html the tree.make template has python 3. Enter python path (Press ENTER if use: /home/tools/continuum/Anaconda3-5.0.1/bin/python): So, I guess python 3 should work for v2.

Y159753 commented 6 years ago

You are both right. I linked the tree make with the wrong version of python. Thank you for such reactivity !

[SOLVED]

I run ./tools/bin/tmake -build ready_for_test, I get some error messages.

And I trace the output log outdir/nv_small.log, I get the messages.

    However, due to incremental compilation, no re-compilation is necessary.

JunningWu commented 6 years ago

@MINZHIJI Same error as yours. have you solved it?

ewq7899987 commented 6 years ago

Try to add the -LDFLAGS -Wl,--no-ad-needed parameters in the VCS_ARGS nvdla/hw/verif/testbench/trace_generator/Makefile (at about line 122)

and the same to the trace_player

MINZHIJI commented 6 years ago

@ewq7899987 --no-ad-needed unrecognized option on /usr/bin/ld. Is it --no-as-needed? I passed by using --no-as-needed. @ewq7899987 , thanks!

But I block by /home/caslab/workspace/tools/CIC_tools/vcs/cur/bin/syscan: line 1896: gmake: command not found. [SOLVED] I try to execute the command which is error part. Then, command can successfully execute! But it will not work on Makefile!

And it maybe gmake problem, I try to use soft link to add gmake on ubuntu by sudo ln -s /usr/bin/make /usr/bin/gmake. And it is successful.

But I block again by more Error-[URMI] Unresolved modules. [SOLVED] The problem is from DesignWare Library. Just disable the DesignWare Library by tree.make

@MINZHIJI , Thanks! For me it was designware DW02_multp,v. I disabled designware in tree.make, but I wish there was a better way to get around this.
