Build error: "g++: No such file or directory"

[mateors]

make build command gave me the following error

g++  -g   -fmax-errors=2  -Wall  -Wextra      unit.cpp  -o bin/lxroot-unit
make: g++: No such file or directory
make: *** [Makefile:46: bin/lxroot-unit] Error 127

my current os

Ubuntu 22.04.1 LTS

Maybe g++ is not installed? Try: sudo apt-get install build-essential

@parke Thank you very much for your quick response.

after installing the build essentials there is bin folder created with the following files

1. lxroot
2. lxroot-unit

then i tried

sudo make unit

and get the following error

unit.sh  test fail

  line       361

  command    env - ./lxr nr -- id -u
  status     0

  expect     '0'
  actual     '0  0'    length 4

  cwd        /tmp/lxroot-unit
  env1       env -

  argv       ./lxr nr -- id -u

Maybe you are running as root? Lxroot does not require root access. Please try cloning/downloading, building, and running 'make unit' as a non-root user. You probably need to delete the /tmp/lxroot-unit directory as it needs to be owned by the non-root user for the unit tests to succeed. Thanks for the error report. I was unaware of this particular issue.

[parke]

Update: The above unit test failure (on line 361) is due to a flaw in the unit test, not a flaw in Lxroot. However, this flaw is only exposed when the unit tests are run as root. I will fix the unit test and push an update to Github.

[parke]

I've pushed the fixed unit test to the master branch: dc153df

So after you do a git pull, the unit tests should now pass (even if you run the unit tests as root).

To repeat myself: I recommend always building, testing, and running Lxroot as a non-root user.

A few of the unit tests are interactive. When prompted, you need to press y and then ENTER to pass these tests.

Thanks again for reporting this issue.

@parke You are great. I appreciate your hard work and enthusiasm.
