Fails to compile with newer versions of ICU library

[pebbe]

Dbxml fails to compile with newer versions of the ICU libary, such as available on Debian 11.
These newer libraries require a compiler newer than c++03, but other parts of dbxml require c++03.

I solved this at home by installing an older ICU library from this source:
https://github.com/unicode-org/icu/releases/tag/release-57-2

I installed it in /my/opt/icu-57.2, and compiled dbxml like this:

./buildall.sh -x "g++ -I/my/opt/icu-57.2/include -L/my/opt/icu-57.2/lib"

This may not be the optimal way to do it.

There may be newer versions of the ICU library that also work. I didn't test that. I chose version 57 because I still had an older version of dbxml that links with version 57.

By the way, dbxml 6 doesn't have this problem.

I still have an old build, and it links with ICU library version 57.
When I rebuild dbxml 6 with the same commands, now on Debian 11, it compiles just fine, but is doesn't link with the ICU library.

The old build of dbxml 6 links to these library, but the new build doesn't:

• libicudata.so.57
• libicui18n.so.57
• libicuuc.so.57
• libnsl.so.1

Maar als ik bij het compileren van dbxml 6 dit toevoeg:

-x "g++ -I/my/opt/icu-57.2/include -L/my/opt/icu-57.2/lib"

dan linkt ie wel met ICU.
