GNU compiler options for ODBc

GNU compiler options for ODBc

[michael.shapiro]

Can I compile, prelink, and link a program with ODBC functions on OS/390
under UNIX System Services using gcc? What are the compiler, prelinker and
linker options?

I used the following the following options with IBM compiler:

compile:        cc -c -W 'c,dll,long,source,list' odbcdrvr.c > odbcdrvr.lst

prelink and link:        cc -W l,p,map,noer -W l,dll,AMODE=31,map -o
odbcdrvr odbcdrvr.o "//'DSN510.SDSNMACS(dsnaocli)'" >odbcdrvr.lnk

Thanks, Michael

	The "GCC/i370" configuration does (or did) support OS/390 USS.  I
don't believe that GCC/i370 will produce correct dynamically loaded
objects because the compiler places the addres of literals in the text
section.  Am I correct in assuming that your ODBC work requires creating a
DLL?
