C++ Cmake can't find "libc10.so.1.8.0"

Hi,

I have 2 separate cmake files, one for my development project and one for my unit testing w/ Boost.Test. I followed the instructions in the docs for the development cmake file and it works flawlessly. However, I am trying to build a separate Cmake file for my unit testing and I keep seeing the following error, I am pulling the TWS API in as well:

Cmake Error in CmdLine:

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Caffe2/Caffe2Targets.cmake:116 (message):
The imported target “c10” references the file

 "/usr/lib/lib/libc10.so.1.8.0"

but this file does not exist. Possible reasons include:

  • The file was deleted, renamed, or moved to another location.

  • An install or uninstall procedure did not complete successfully.

  • The installation package was faulty and contained

    “/usr/lib/x86_64-linux-gnu/cmake/Caffe2/Caffe2Targets.cmake”

but not all the files it references.

My CMake File:

file(GLOB SOURCES .cpp ${TWS_SOURCE}/.cpp)

target_include_directories(${TEST_NAME} PRIVATE ${TORCH_INCLUDE_DIRS})

add_test(NAME ${TEST_NAME} COMMAND ${TEST_NAME})

endforeach()

runtests.sh file to build and run the test_suite

if [ ! -d “build” ]; then
mkdir -p build

cd build
cmake -DCMAKE_PREFIX_PATH=~/libtorch …
cmake --build . --config Release
if [ $? -eq 0 ]; then
clear

Any help would be appreciated!

Thanks,

$ sudo ln -s /usr/lib/x86_64-linux-gnu/ /usr/lib/lib

Since libc10.so.1.8.0 is located in /usr/lib/x86…, making a soft link solves the problem
