Firebird Embedded: intl subdirectory is ignored on Linux

[mikekaganski]

In LibreOffice, Firebird Embedded is built using this sequence (simplified; the script is here):

./configure --without-editline --with-wire-compress=no --enable-shared --disable-static
make

The resulting DLLs (libfbclient.so, libEngine12.so, and the directory intl with libfbintl.so and fbintl.conf) are put into LibreOffice install directory (configurable). Same on Windows, except file names are respectively different (ifbclient.dll, Engine12.dll, intl/fbintl.dll, intl/fbintl.conf).

This works, except this problem: on Linux, executing CREATE TABLE mytable (c char(2) character set WIN1252) fails with

*unsuccessful metadata update *EXT_LOG *CHARACTER SET WIN1252 is not installed caused by 'CREATE TABLE mytable (c char(2) character set WIN1252)'

Firebird looks up its intl directory under /usr/local/firebird, not in the subdirectory where the main DLLs are located. Note that the same configuration works on Windows, and the DLLs directory is searched first when looking for intl.

What is our mistake? What needs to be specified or configured or moved or ... to let Linux build find its intl data?

Thank you!
