osqp-cpp's Issues

Compile sample code issues

I face this error then compile sample code from readme
specifically it happens when I declare osqp::OsqpSolver solver;
Any ideas what might be the issues ?

/usr/bin/ld: /usr/local/lib/libabsl_strings.a(numbers.cc.o): relocation R_X86_64_PC32 against symbol `_ZN4absl14ascii_internal13kPropertyBitsE' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: bad value
collect2: error: ld returned 1 exit status

Initial solution

How can I set initial solution?
There is not way to modify solver.primal_solution() since it is const, and I can not find a way to set initial solution

Right now the library breaks because the latest version of OSQP removes one of the headers osqp-cpp relies on: ctrlc.h. FetchContent allows to select specific versions of a library by means of GIT_TAG: could you add this functionality to osqp-cpp? Also, it would be great if osqp-cpp defined its own Git tags, too. Thanks!

Error encountered during make

I encountered following error messages during make:

I'm running it on Raspberry Pi OS (Debian Buster). But I don't think this is the source of the problem...

ctrlc.h header issue

Hi, I am trying to build osqp-cpp on Raspberry Pi with Ubuntu 20.04. It was successfully built before.

But currently, OSQP requires cmake 3.18 which is not original available in Ubuntu 20.04. Then I updated to the latest cmake version.

we configure the CMakeLists for our application(ROS) like this:

include(FetchContent)
# OSQP
if (NOT TARGET osqp-cpp)
  set (PYTHON OFF CACHE INTERNAL "Turn off python for OSQP-CPP")
  message(STATUS "${PROJECT_NAME}: `osqp-cpp` targets not found. Attempting to fetch contents...")
  FetchContent_Declare(
    osqp-cpp
    GIT_REPOSITORY https://github.com/google/osqp-cpp/
    GIT_TAG        origin/master
  )
  FetchContent_MakeAvailable(osqp-cpp)
else()
  message(STATUS "osqp-cpp: `osqp` targets found.")
endif()

When we build package, got issue: fatal error: ctrlc.h: No such file or directory. could your tell me what is this header?
Thanks for your help.
