--with-textcat: configure error?

Hello,

With Dovecot 2.3.18 on AlmaLinux 8 I’m trying this:

LIBEXTTEXTCAT_LIBS="-L/usr/lib64 -lexttextcat" ./configure --with-textcat

… which gives me:

checking for special_textcat_Init in -lexttextcat... no checking for special_textcat_Init in -ltextcat... no configure: error: Can't build with textcat support: libtextcat or libexttextcat not found

I do have:

ls -la /usr/lib64 | grep textcat lrwxrwxrwx 1 root root 26 Oct 12 2019 libexttextcat-2.0.so.0 -> libexttextcat-2.0.so.0.0.0 -rwxr-xr-x 1 root root 22128 Oct 12 2019 libexttextcat-2.0.so.0.0.0

Is there some way of knowing what command it’s actually running that makes it say “libtextcat or libexttextcat not found”?

Thank you!

cheers, -Felipe Gasper
