    Dear all,
    I successfully downloaded/compiled SOFA and some additional plugins such as Preassembled Mass, Sofa Python, or Compliant.
    But we recently have faced a common issue in compiling the Flexible plugin with one of my colleagues.
    I tried to compile with both ninja and make but the result is the same.

    [12/14] Linking CXX shared library lib/libFlexible.so.0.1
    FAILED: lib/libFlexible.so.0.1

    It looks like a linking problem… Any idea?
    I’m using gcc9 and cmake 3.16.3
    Many thanks and have a good day,

    Arnaud

collect2: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.

    This may come from some missing dependency, thus undefined ref.
    I will have a look at it.

    This was indeed an issue @amazier
    This was fixed in PR #1302.

    Since the v19.12 branch is a release branch, it is frozen when released. Starting from v20.06, a new policy will be applied: backporting all fixes to the previous release. So that the community, you all guys, can rely confidently on a robust and stable release.

    Best
