Building failed (tlb_generate_block.dir/build.make:62)

[Obadah-H]

Building ton gives an error. Commands I'm using to build:

    git submodule update --init --recursive
    mkdir build && cd build
    cmake -DCMAKE_BUILD_TYPE=Release ..
    cmake --build .

The last command gives the following output:

try to use g++-7 for C and CXX compilers. It works for me on Ubuntu 14.04

[Obadah-H]

I'm using g++-7 and it's the default one. I'm running Ubuntu 18.04

[logvik]

You can try to use it -> https://github.com/akme/ton-node/blob/master/Dockerfile

[Obadah-H]

Thanks for this solution, my problem is solved. I'll keep this thread open as this solution doesn't solve the BUILDING error.

[ton-blockchain]

Do you use an operating system with CP/M-compatible line breaks?

[Obadah-H]

Yep - I wrote that I'm using Ubuntu 18.04
