libtorrent-rasterbar.so got segment fault when starting it
Brubbish opened this issue · comments
Please provide the following information
libtorrent version (or branch): branch RC_2_0
platform/architecture: Ubuntu20.04, amd64 on a wsl2
compiler and compiler version: gcc 11.4.0
please describe what symptom you see, what you would expect to see instead and
how to reproduce it.
I compiled libtorrent strictly follow the steps in https://libtorrent.org/building.html#building-with-cmake, which i cmake then ninja
My cmake command is like: cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_STANDARD=14 -Dbuild_tests=ON -G Ninja ..
after built by ninja, I got some libtorrent-rasterbar.so files, but they cannot run properly. Here is the gdb page, it seems that it stops at very beginning.
(No debugging symbols found in ./libtorrent-rasterbar.so)
(gdb) r
Starting program: /home/fuzz-test/libtorrent/build/libtorrent-rasterbar.so

But all the tests can be passed.
I am confused about how to use this executable file properly
the best way to ensure you're building libtorrent in an ABI compatible way to work in your program is to point to it as a dependency within CMake itself. I believe that will make cmake use the same build configurations for your executable as the libtorrent library
