Hi All,
I'm trying to built FB from the source code v. 2.5.2.26540-0 on AIX 6.1
(PPC). I've made some minor changes in the build script to let it create
./configure script, also a couple of source code files slightly changed
(mostly to avoid conflicts).
But now I'm facing a problem - attempt to create/access to DB file causes
core dump in Jrd::LockManager::attach_shared_file() function.
Actually, it happens during the build when empty.fdb and other DB files are
created. Manually retrying create_db I can get all all .fdb files created
(files are created in spite of core dump).
AIX 6.1 PPC, IBM XL C/C++ for AIX, V12.1
My settings:
export CC=xlc_r
export CXX=xlC_r
export CFLAGS="-q64 -gxlc -D_REENTRANT"
export CXXFLAGS="-q64 -gxlC D_REENTRANT"
./autogen.sh --enable-debug=yes
Also I set FIREBIRD to .../firebird, FIREBIRD_LOCK to one of temp folders,
and LIBPATH (LD_LIBRARY_PATH) to .../firebird/lib
I'd like to share some results of debugging.
Assert happens after the following sequence of function calls (in create_db
exec):

After that point, m_header (and it's lhb_version field):

But according to lock_proto.h (line line 107 and above), lhb_version should
be equal to LHB_VERSION = PLATFORM_LHB_VERSION + BASE_LHB_VERSION, i.e.
128+17 = 145 decimal, or 221 octal.
Actually, this is the value of lhb_version field which I see during
previous call of LockManager::attach_shared_file (during execution of
isc_create_database(), line 22 in create_db.cpp file):

Continue my debugging. Any ideas would be appreciated.
