EnvironmentError: No tool named 'fastcpp': not a Zip file:

Question

I am compiling some proprietary code and trying to build an image. Here I am getting an error of

EnvironmentError: No tool named 'fastcpp': not a Zip file:

I downloaded the fastcpp from here but not able to understand how can I install it as it has some code files having.hpp extensions.

I have already install scons successfully.

Can anyone explain what is fastcpp and how to use it to fix above error?

UPDATE: 19/08/2020

It has ComSConstruct.py module located at '${BUILD_ROOT}/tools/build/scons/build' still it is giving above errors.

I replaced this above path with the path where FastCpp files are present. Now the error is changed to ComSConstruct tool.

EnvironmentError: No tool named 'ComSConstruct': not a Zip file:

Answer 1

Finally, I got the solution.

There were some fixes in the proprietary code. I got the patches and applied them manually.

Then, updated the clang 3.4 to clang 4.0 by following below commands. (Failed to install higher clang versions. I think, probably 14.0 is not supporting higher versions.)

sudo apt-add-repository "deb http://apt.llvm.org/trusty/ llvm-toolchain-trusty-4.0 main"
sudo apt-get update
sudo apt-get install clang-4.0 lldb-4.0

Compiled again and it worked. :)

You have to delete scons in your Linux. That scripts use local scons environment.

in error codes:

-> /usr/lib/scons : you have a scons lib by apt-get install scons maybe

-> if you autoremove scons and then That script run in local scons environment in ../build/ms (it might Q codes)
