Problem description

When using cmake, the third-party library has interdependence and an error occurs. Looking forward to your reply.

Errors:

/usr/bin/ld: /home/xxx/lib/libobjMesh.a(objMesh.o): warning: relocation against `_ZTIi@@CXXABI_1.3' in read-only section `.text.unlikely'
 
/usr/bin/ld: /home/xxx/lib/libconfigFile.a(configFile.o): relocation R_X86_64_PC32 against symbol `_ZTV10ConfigFile' can not be used when making a shared object; recompile with -fPIC

Reproducible example code

No response

Is this a regression? Put the last known working version here if it is.

Not a regression

I confirm the issue, reproducible example can be found here

Interestingly, for my particular case it got fixed by using a conda's compiler. Originaly, my local compiler (GNU 13.1.1) was used. After I used conda's (GNU 11.3.0), the issue was fixed.

Not sure if this is helpful for your setup, but for anyone also compiling cpp files in the cmake. I added SHARED to add_library and it worked.

For example:

add_library(${PROJECT_NAME} SHARED
  src/datastructures/Graph.cpp
  src/datastructures/SearchQueue.cpp
  src/datastructures/State.cpp
)
