Install Root with libgsl.so

perev · August 30, 2022, 12:41am

When I am trying to install Root6.24 I got the following error:

/afs/rhic.bnl.gov/@sys/opt/star/sl73_gcc485/lib/libgsl.so: error adding symbols: File in wrong format
collect2: error: ld returned 1 exit status

The reason is evident, my Root is 64bits but libgsl library 32bits.
There is 64bits libgsl.so but I do not know how to forse cmake to use the correct library.
I tried to use GSL_LIBRARIES variable with no success.
What can I do?

Hi! In this case, you can try to build ROOT with the -Dbuiltin_gsl=ON option. See this file for the full list of build options:

github.com

root-project/root/blob/master/cmake/modules/RootBuildOptions.cmake#L96


      
          ROOT_BUILD_OPTION(builtin_clang ON "Build bundled copy of Clang")
          ROOT_BUILD_OPTION(builtin_cling ON "Build bundled copy of Cling. Only build with an external cling if you know what you are doing: associating ROOT commits with cling commits is tricky.")
          MARK_AS_ADVANCED(builtin_cling)
          ROOT_BUILD_OPTION(builtin_cppzmq OFF "Use ZeroMQ C++ bindings installed by ROOT (requires network)")
          ROOT_BUILD_OPTION(builtin_davix OFF "Build Davix internally (requires network)")
          ROOT_BUILD_OPTION(builtin_fftw3 OFF "Build FFTW3 internally (requires network)")
          ROOT_BUILD_OPTION(builtin_freetype OFF "Build bundled copy of freetype")
          ROOT_BUILD_OPTION(builtin_ftgl OFF "Build bundled copy of FTGL")
          ROOT_BUILD_OPTION(builtin_gl2ps OFF "Build bundled copy of gl2ps")
          ROOT_BUILD_OPTION(builtin_glew OFF "Build bundled copy of GLEW")
          ROOT_BUILD_OPTION(builtin_gsl OFF "Build GSL internally (requires network)")
          ROOT_BUILD_OPTION(builtin_llvm ON "Build bundled copy of LLVM")
          ROOT_BUILD_OPTION(builtin_lz4 OFF "Build bundled copy of lz4")
          ROOT_BUILD_OPTION(builtin_lzma OFF "Build bundled copy of lzma")
          ROOT_BUILD_OPTION(builtin_nlohmannjson OFF "Use nlohmann/json.hpp file distributed with ROOT")
          ROOT_BUILD_OPTION(builtin_openssl OFF "Build OpenSSL internally (requires network)")
          ROOT_BUILD_OPTION(builtin_openui5 ON "Use openui5 bundle distributed with ROOT")
          ROOT_BUILD_OPTION(builtin_pcre OFF "Build bundled copy of PCRE")
          ROOT_BUILD_OPTION(builtin_tbb OFF "Build TBB internally (requires network)")
          ROOT_BUILD_OPTION(builtin_unuran OFF "Build bundled copy of unuran")
          ROOT_BUILD_OPTION(builtin_vc OFF "Build Vc internally (requires network)")

Like this, it will build a custom version of GSL just for ROOT that should always work, independent on what you have on the system.

You need: yum install gsl-devel

Hi Jonas, thank you for the answer.
Yes, I was trying to use "-Dbuiltin_gsl=ON " with no result.
Is it really no option to tell cmake to use the gsl library
which does exist and I know where it is?
I see that this option by default is OFF. Actually I do not care about
Gsl lib, I need only to install Root6. It should be some simple way
how to point it up where the library is placed.
This cmake found wrong library (32bit instead of 64bits).
May be there is a way to search 64bits libraries only?

Hi Wile_E_Coyote,

yum install gsl-devel
I am not experienced in Root6,
What does it mean “yum”

You need to talk to your system administrator.
