i'm currently trying to compile & make a port of firebird on openbsd,
but have a few problems.

- under openbsd 3.4-stable (with gcc-3.2.3)
when compiling:
$ eg++ -DBOOT_BUILD -I../src/include/gen -I../src/include
-DPROD_BUILD -c ../src/jrd/gds.cpp -o ../temp/boot.gpre/jrd/gds.o
../src/jrd/gds.cpp: In function `int gds__msg_open(void**, TEXT*)':
../src/jrd/gds.cpp:1423: warning: comparison is always false due to limited
range of data type
../src/jrd/gds.cpp: In function `void gds__temp_dir(TEXT*)':
../src/jrd/gds.cpp:2262: `WORKFILE' undeclared (first use this function)
../src/jrd/gds.cpp:2262: (Each undeclared identifier is reported only
once for
each function it appears in.)

WORKFILE is defined in file_params.h, so ...

- on 3.4-current (with gcc-3.3.2)

if someone has any ideas ?

when was the last sucessful test on openbsd ?

note than i take a look to freebsd port
http://www.freebsd.org/cgi/cvsweb.cgi/ports/databases/firebird/
