NVDLA Cmod library not found

[luisarocas]

When following http://nvdla.org/vp.html, in step 2.4.1 I obtain the error: NVDLA Cmod library not found.

Everything has been followed as explained in nvdla.org/vp, the system requirements are all met. I have tried to repeat the process several times and I keep receiving the same error.

The paths of vp and hw are well defined. Can someone help me?

I think the problem is in: tools/bin/tmake -build cmod_top After doing this command I do not have hw/outdir//cmod/release. The header files and library should have been generated in release folder but that directory has not been created.

@luisarocas please share log for "tools/bin/tmake -build cmod_top"

[luisarocas]

The log file outdir/build.log contains:

[fanqifei]

Hi @luisarocas, from outdir/build.log the cmod building looks like incomplete. The sub-units like cdma, css are not built. Could you please cleanup the cmod output directory and then perform a clean build?

[luisarocas]

I notices that when doing sudo tools/bin/tmake -build cmod_top many errors appear. I still do not know what is wrong. Can someone help me?:

Isn't sudo messing something with paths?

[prasshantg]

@luisarocas why are you using sudo? It will change the paths you have set.

[javiergcanada]

Hello @luisarocas , I have recently experienced a similar problem to yours. (issue nvdla/sw#134 , please if someone knows how to correctly link it). I got the same error while trying to compile the CMOD library, but in my case its due to java, perl and the rest of the programs being located on /usr/bin, and the make instruction cannot obtain permission to deal with that folder. I haven't found any solution yet, but make sure if that is nor your same issue

[fanqifei]

Hi @luisarocas, did you follow http://nvdla.org/hw/v1/integration_guide.html or http://nvdla.org/vp.html to install the tools like g++, java? The commands of running cpp and g++ are correct. The issue is that they were not found in /home/utils/gcc-4.9.3/bin. Could you please check whether they exist in that path? Using sudo is not necessary actually.

[fanqifei]

Hi @javiergcanada , could you check the setting in tree.make? CPP, GCC are defined in tree.make. Tree.make is generated in first step of http://nvdla.org/hw/v1/integration_guide.html#tree-build

[javiergcanada]

Hi @fanqifei, as you can see in the screenshot i posted on nvdla/sw#134, I think I'm defining the location of CPP and GCC as /usr/bin correctly. I'm also not getting any error message on the next step, telling me that they were incorrectly located, it apparently just doesn't have permission to access those files. Thank you for your help.

Maybe after executing sudo command now you have some leftovers belonging to root. Try something like:

find <your_hw_dir> -exec chown <your-user-name>:  {} \;

Or remove the project from disk and checkout from repository again.

As for configuring GCC location... Keep in mind that CMOD may still use gcc installed with the OS. See https://github.com/nvdla/hw/pull/191

Hi @javiergcanada , in my tree.make, the setting are below: CPP := /home/utils/gcc-4.8.2/bin/cpp GCC := /home/utils/gcc-4.8.2/bin/gcc When you run make to create tree.make, I think you should type the full path of cpp and gcc, like /home/utils/gcc-4.9.3/bin/cpp, not /usr/bin.

@javiergcanada @luisarocas

Please try with docker image (https://hub.docker.com/r/nvdla/vp) which has all dependencies install to build cmod and vp

Step 1. Run docker image docker pull nvdla/vp docker run -it -v /home:/home nvdla/vp

Step 2. Build CMOD git clone https://github.com/nvdla/hw.git cd hw/ git checkout origin/master make

tools/bin/tmake -build cmod_top

Step 3. Build VP

cd ..

git clone https://github.com/nvdla/vp.git cd vp/ git submodule update --init --recursive

cmake -DCMAKE_INSTALL_PREFIX=build -DSYSTEMC_PREFIX=/usr/local/systemc-2.3.0/ -DNVDLA_HW_PREFIX= -DNVDLA_HW_PROJECT=nv_small

[Aditi896]

All the steps involved seemed to run successfully for me. But it said CMOD Library not found.

The hardware project is named nv_full by default. Files were generated under NVDLA/hw/outdir/nv_full/cmod. So when we run the cmake in the vp directory, give -DNVDLA_HW_PROJECT=nv_full in place of -DNVDLA_HW_PROJECT=nv_small

Check if this works for you.
