I put too many hours into it. There are so many other projects that are out there. I may install firebird 2.1 and try that to see if it is a difference between versions. I don't know how many people use gnucobol with firebird gpre. Maybe someday there will be a more extensive tutorial for installing it and getting it up and running. thx. for the suggestion - J.McNamara -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel

I believe gnucobol is an implementation of opencobol, in which case this is probably relevant... http://www.ibphoenix.com/resources/documents/search/doc_382 Regards Paul -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
[Firebird-devel] gpre cobol can't access memory segfault with trace
hi- First off, thx. for very cool help earlier with tips to add flags or switch to another version of gcc that is earlier. I got firebird source to compile because my icu is under 59 for now. I am trying to run a simple connect and disconnect to the firebird db using cobol gpre. It goes into fits around the lines where it tries to connect in my output file from gpre. I ran a back trace on it as per Brian Tiffin's suggestion at gnucobol. I was able to use gdb. I am posting the back trace. I can't make heads or tails of what it is telling me other than there are memory problems in the code. If you know what the back trace means can I have a hint please? i got flamerobin and command-line isql to work. thx in advance - jim (gdb) bt #0 0x75dd5957 in memcpy@GLIBC_2.2.5 () from /lib64/libc.so.6 #1 0x767cda94 in Firebird::Array >::push (itemsSize=19, items=0xf7ff24a0 , this=0x7fffcd28) at ../src/include/../common/classes/array.h:328 #2 Firebird::ClumpletWriter::ClumpletWriter (this=0x7fffccf0, k=, limit=, buffer=0xf7ff24a0 , buffLen=19, tag=) at ../src/common/classes/ClumpletWriter.cpp:88 #3 0x764fb754 in isc_attach_database ( user_status=, file_length=60, file_name=, public_handle=0x602190 , dpb_length=, dpb=0xf7ff24a0 ) at ../src/jrd/why.cpp:1422 #4 0x00400f77 in Moon_ (entry=0) at simple15.c:135 #5 0x00400be5 in Moon () at simple15.c:48 #6 0x00400bd0 in main (argc=1, argv=0x7fffdf98) at simple15.c:36 (gdb) -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
