[Firebird-odbc-devel] a compilation error about string literals in the version 2.0.4 (155)

[m***@beroal.in.ua]

Hello. When compiling the version 2.0.4 (155) of OdbcJdbc for Linux
(ArchLinux, package: https://aur.archlinux.org/packages/firebird-odbc/
), a compilation error appears. AFAIK, it appears because GCC moved to
the "C++11" standard, and the source code is not compatible with this
standard. The source code includes macros for string literals that clash
with the new C feature called "user-defined literals", see
http://en.cppreference.com/w/cpp/language/user_literal . I am not
familiar with this obscure feature, so I am not able to fix the source
code. Instead, I give GCC a parameter to parse the source code with the
old standard "C++03". I patched
"OdbcJdbc/Builds/Gcc.lin/makefile.linux". IMO, the source code should be
fixed in the near future.

The error message: {{{
