Hi @lenhuy, this is likely caused by missing dependencies. Most of them are present in the case of Ubuntu Desktop, but for Ubuntu Server you need to install some manually (e.g. build-essential libc-dev). Check the MRAA's building documentation for additional details, if you can get MRAA to build then UPM will do so too.

P.S. This can also be a cmake bug, but we'll discuss further if dependencies won't fix this for you. In that case please also include the cmake configuration step output.

I suspect the problem is not a missing thread implementation but one of the other dependencies like @Propanu mentioned.

Can you provide the rest of the CMake output?

Also, verify you have a 'libthread.so' (not libpthreads.so).

For reference...

The CMake find_package call for Threads creates multiple test snippet builds to determine a usable thread implementation. It's normal to see errors in the CMakeError.log for the failing checks (it should hopefully find one and log that to CMakeOutput.log). For example, my CMakeError.log looks nearly identical to yours (the pthread_create fails for two runs (1st, w/o a thread library specified and the 2nd with -lpthreads - note the 's' on pthreads - libpthreads.so prb doesn't exist on your ubuntu machine, but you should see a libpthread.so).

If I look in my CMakeOutput.log, I see the passing thread check:

Determining if the include file pthread.h exists passed with the following output:
Change Dir: /tmp/build/CMakeFiles/CMakeTmp

Thank you for quick response.

1. I had build-essential libc-dev installed
2. mraa was built successfully
3. CMakeOutput.log is attached CMakeOutput.log

@lenhuy,

Can you provide the direct output from the cmake binary (everything after the call to 'cmake ..').

@lenhuy, you are missing SWIG, you can solve this by running sudo apt install swig.

[lenhuy]

cmake successfully after "sudo apt install swig". Thank you.

How do I compile grove-grovelight.cxx in ~/upm/examples/c++/grove-grovelight.cxx? "g++ grove-grovelight.cxx -o grovelight" give error: grove-grovelight.cxx:29:26: fatal error: grovelight.hpp: No such file or directory.

[Propanu]

Hi @lenhuy, sorry for the delay on this. The simplest way is to enable the BUILDEXAMPLES=ON CMake switch. You can also compile by hand, but you have to specify the include path -I, library path -L and linker flags -lupm-grove. Pkg-config can also help here. I highly recommend you use the upm-light library instead of the grove module though, as that has been deprecated.

test1.cpp:

include "mraa/common.hpp"

include "mraa/types.h"

include "upm/light.hpp"

int main(int argc, char** argv) { int upm::Light light(512); return 0; }

g++ test1.cp -o test1 -lmraa -lupm-light error: terminate called after throwing an instance of 'std::runtime_error' what(); Light:Light_init() failed. Aborted (core dumped)

Where is the implementation of the constructor Light(unsigned int pin)?

[lenhuy]

Need to be root user to access the GPIOs, so need to include sudo to run "sudo ./test1".
