  • [gentoo-user] error: template with C linkage

    From Helmut Jarausch@21:1/5 to All on Mon Jan 9 12:40:01 2023
    Hi,
    for some of my (older) local ebuild I get the error
    template with C linkage

    What is the reason for this message?
    How can I change "C linkage" to "C++ linkage"

    Many thanks for a hint,
    Helmut

    Your C++ code opens an 'extern "C" { ..' block (maybe via included header)
    but apparently does not close it correctly. Defining a C++ template in a C-linkage scope makes no sense, hence the complaint.
    To fix you need to find the 'extern "C"' section and make sure it is closed.

    cheers
