        Hello Camilo,<br>
        <br>
        you are affected by gfortran-10 and gcc-10 reporting errors for code<br>
        that compiled by gfortran-9 and gcc-9.<br>
        <br>
        You can either try and uninstall gcc-10 and gfortran-10 or, most likely<br>
        easier, edit the file simfactory/mdb/optionlists/generic-mp-10.cfg and<br>
        change all gfortran-10, gcc-10, g++-10 to gfortran-9, gcc-9, g++-9 then<br>
        reconfigure once more using the modified option list:<br>
        <br>
        simfactory/bin/sim build --reconfig --optionlist simfactory/mdb/optionlists/generic-mp-10.cfg<br>
        <br>
        There are also options you can add to F90FLAGS, CFLAGS, CXXFLAGS and<br>
        LDFLAGS to have gfortran-10 and gcc-10 revert to the old behaviour.<br>
        <br>
        Please see these ET tickets for details:<br>

        <br>
        The fixes developed in there and in a couple of other tickets (since<br>
        the options are not a solution for the general case since they are<br>
        compiler version specific) will be backported to the release branch<br>
        as soon as they are fully tested and reviewed.<br>
        <br>
        Yours,<br>

                Dear Roland,<br>
                <br>
                I removed the file <a href="mailto:campos@MacBook.ini">campos@MacBook.ini</a>, then I run echo >..., and ru<br>
                n ./simfactory..., and it started to compile. It seems it finished with no problems (picture 12.06.24). When I tried to build the toolkit using the j2 option, it produced an error (picure 12.07.05) related to the Xcode, so I typed the command suggested by the error but at the end of the process it produced an error (pic 12.09.36)<br>
                <br>
                I started the whole process again, updating the Xcode, refreshing all the prerequisites but I got the same error. I'm not sure if it's connected with the previous error with <a href="mailto:campos@MacBook">campos@MacBook</a>. It does not look like though.<br>
                <br>
                Thank you!<br>
                <br>
                Best,<br>
                Camilo<br>

                Hello Camilo,<br>
                <br>
                Dear Roland,<br>
                <br>
                I run the commands you mentioned but I keep getting the following erro<br>
                r:<br>
                 <br>
                <br>
                 Error: specified value <a href="mailto:campos@MacBook">campos@MacBook</a> for key nickname does not<br>
                >> match converted pattern ^[a-zA-Z0-9_+-\.]+$<br>
                <br>
                 I keep seeing the same file: <a href="mailto:campos@MacBook.ini">campos@MacBook.ini</a>, in the<br>
                mdb/machines directory, so I believe the problem is there. What do<br>
                you think?<br>
                <br>
                Well maybe. Depends on whether the file keeps reappearing if you delete<br>
                it, then run<br>
                <br>
                echo >$HOME/.hostname "compos_MacBook"<br>
                <br>
                then run ./simfactory/bin/sim setup-silent again.<br>
                <br>
                The presence of the file alone is not the issue, only if it is actually<br>
                used.<br>
                <br>
                Certainly it cannot hurt to remove it to verify it is not being<br>
                recreated. What has me more confused is that running these two commands<br>
                :<br>
                <br>
                echo >$HOME/.hostname "compos_MacBook"<br>
                <br>
                ./simfactory/bin/sim setup-silent<br>
                <br>
                there should have been a file<br>
                simfactory/mdb/machines/compos_MacBook.ini (ie with an underscore).<br>
                <br>
                Yours,<br>
                Roland<br>
