  • Ticket #29152 – Description

    initial v4  
    1 The error occurs when linking:
     1Follow-up from #30163, where libtool's fallback to static library build for `giac` caused linker errors while building sagelib.
    22
     3This is fixed by passing `-no-undefined` to the libtool linking flags, by setting `AM_LDFLAGS=-no-undefined`.

     5Affected packages can be found as follows:

    821This is a common issue especially when using libtool to link Windows DLLs and should hopefully be straightforward to fix.
