Newbie request: stuck with installation error
Hello, I am currently installing the Omnisci repo downloaded from master branch. My usecase is to separate the execution engine from query optimization, so that we will be running DB operations across multiple devices as well as systems. However, I am stuck with the installation and cannot solve the issue. I have the necessary dependencies installed but still stuck with make. Could you guys help me?
I am getting this error
Scanning dependencies of target DateTimeUtilsTest [ 25%] Generating libProfileUtils.so /bin/sh: 1: nvcc: not found Tests/CMakeFiles/ProfileUtils.dir/build.make:61: recipe for target 'Tests/libProfileUtils.so' failed make[2]: [Tests/libProfileUtils.so] Error 127 CMakeFiles/Makefile2:3207: recipe for target 'Tests/CMakeFiles/ProfileUtils.dir/all' failed make[1]: [Tests/CMakeFiles/ProfileUtils.dir/all] Error 2 make[1]: Waiting for unfinished jobs....

I did run the dependency installer scripts as well as I get nvcc --version as 10.1 but somehow I am not able to solve this one. Could you guys help me figuring this out? Thanks a lot!

Hi @bala,
Thanks for joining the forum and trying out our software.
Generally speaking the /bin/sh: 1: nvcc: not found means that the PATH and LD_LIBRARY_PATH don't point to the right paths or they aren't exported so you shell is working but a script that's running on a new shell isn't seeing the two variables.
Assuming you are on ubuntu, have you run the /usr/local/mapd-deps/mapd-deps.sh shell? Anyway you can try to export both variables before to run the make command (export PATH and export LD_LIBRARY_PATH)

As @candido.dessanti mentioned, the issue is that for some reason
nvccisn't being found in your PATH. It could be something as simple as logging out and back in to pick up the CUDA env vars, since it appears you were able to callnvccin a separate terminal.There appears to be a second issue with the
fatal: Not a git repository. It looks like you might have downloaded the .zip of the repo from Github, which is not currently supported. Could you instead usegitto clone the repo with:git clone https://github.com/omnisci/omniscidb.gitI've filed a ticket for the first issue to improve how nvcc gets found and used: https://github.com/omnisci/omniscidb/issues/553

@candido.dessanti and Andrew
Hey. Thanks for the faster response. We have already tried adding in the CUDA location into path using
export PATH=/usr/local/cuda-10.1/bin\${PATH:+:\${PATH}} export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
Even then, I get the same error. Maybe I miss something?

Our usecase is to try splitting a SQL query and execute it in different DBMS - running on top of different execution devices - based on their costs, somewhat like the exchange operator but in the level of different DBMSes. Do let me know if you need anymore information.
