Hi, I am the maintainer of jimtcl package that i adopted it several months ago https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=993599. now I want to fix the bug from Debian user. In short, he want to add ipv6&math feature for jimtcl package. I tried it but fail:

dh_auto_configure -- --shared --utf8 --ipv6 --math
        ./configure --build=x86_64-linux-gnu --prefix=/usr --includedir=\${prefix}/include --mandir=\${prefix}/share/man --infodir=\${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --disable-option-checking --disable-silent-rules --libdir=\${prefix}/lib/x86_64-linux-gnu --runstatedir=/run --disable-maintainer-mode --disable-dependency-tracking --shared --utf8 --ipv6 --math

To be honest, I do know not much about jimtcl before maintaining it. So, I have to ask for help here, sorry.

Thanks for the report. I don’t know much about Debian packaging so we are equal 😀. What version of jimtcl is it using?

[yuzibo]

It is 0.81 on Debian also. Sorry, I'm not a qualified maintainer so far for jimtcl:(. But I think I still do my best to make the user experience a better jimtcl on Debian:) The debian repo is here: https://salsa.debian.org/debian/jimtcl. In fact, the jimtcl is perfect because I can config these options from source code with preinstalled jimsh and it works. I suspect the original maintainer of the package was intentional

I think the problem is trying to do one in-tree build (shared) and one out-of-tree build (static). Do one or the other but not both. Since you want both builds, make them both out-of-tree. Something like this, but with a few other places changed to account for the shared out-of-tree build:

I'm going to close this issue since I think it can be dealt with as described above

I am appreciated for help here. But it seems I forget the issue.:( Sorry for not responding for a long time. I will update it before the bookworm release. Thanks again.
