Timers problem when Boost is also used

[eao197]

Hi! Thanks for reporting this.
Today is too late in my country. I'll take a look tomorrow.

I don't know is it a correct way to go but if I change a line in ~/.conan/profiles/default:

- compiler.libcxx=libstdc++
+ compiler.libcxx=libstdc++11

and then perform commands:

conan install ../ --build=missing
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build . --config Release

then the sample program compiled and linked without an errors.

I suppose that the problem in the flag _GLIBCXX_USE_CXX11_ABI=0 that is added when Boost is mentioned in conanfile.txt.

If you don't use Boost then sample project is compiled with the following flags:

CXX_FLAGS =    -O2 -DNDEBUG    -std=gnu++17

CXX_DEFINES = -DSO_5_STATIC_LIB

CXX_INCLUDES = -isystem /root/.conan/data/sobjectizer/5.7.1/stiffstream/stable/package/2a30b7d6ea2202e5393ebda51c8729dd2162b9f8/include

But if Boost is added then an additional flag is added:

CXX_FLAGS =    -O2 -DNDEBUG    -D_GLIBCXX_USE_CXX11_ABI=0 -std=gnu++17

CXX_DEFINES = -DSO_5_STATIC_LIB

CXX_INCLUDES = -I/root/.conan/data/boost/1.73.0/_/_/package/91ae5bfe3845753bb397c926531b17117d20c8f9/include -I/root/.conan/data/zlib/1.2.11/_/_/package/6af9cc7cb931c5ad942174fd7838eb655717c709/include -I/root/.conan/data/bzip2/1.0.8/_/_/package/da606cf731e334010b0bf6e85a2a6f891b9f36b0/include -isystem /root/.conan/data/sobjectizer/5.7.1/stiffstream/stable/package/2a30b7d6ea2202e5393ebda51c8729dd2162b9f8/include

And I think that the presence of _GLIBCXX_USE_CXX11_ABI leads to different name mangling and because of that names of some SObjectizer's methods can't be found in the static library that was built (I suppose) without _GLIBCXX_USE_CXX11_ABI.

Unfortunately, I'm not an expert in Conan nor CMake and don't know how to fix it quickly. It needs some time for further investigation.

Thank you so much! Your advice is working!

If you do not want to patch ~/.conan/profiles/default, you may specify compiler.libcxx by the following flag in conan install: -s compiler.libcxx=libstdc++11. The resulting commands are:

conan install ../ --build=missing -s compiler.libcxx=libstdc++11
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build . --config Release
