1*57984Sbostic# @(#)README 5.2 (Berkeley) 02/14/93 257978Sbostic 3*57984SbosticThis is the directory to use for creating a library of the dbopen(3) 4*57984Sbosticroutines. The Makefile builds the base system. By changing it and 5*57984Sbosticthe compat.h file, you should be able to pick and choose the various 6*57984Sbosticthings your system needs to make libdb run. 7*57984Sbostic 8*57984SbosticThe knobs that you may have to turn: 9*57984Sbostic 10*57984SbosticIn the Makefile: 11*57984Sbostic If you don't have mktemp or mkstemp on your system, add 12*57984Sbostic "mktemp.o" to the COMP list. 13*57984Sbostic 14*57984SbosticIn include/compat.h: 15*57984Sbostic Before attempting to build this library, you should skim through 16*57984Sbostic the compat.h file, and adjust it as necessary for your system. 17*57984Sbostic It's possible to use the #ifndef construct to figure out if a 18*57984Sbostic #ifdef has been set, but C provides no similar method to figure 19*57984Sbostic out if a typedef has been done. All of the typedef's are grouped 20*57984Sbostic at the top of compat.h, your compile errors will tell you which 21*57984Sbostic ones you need. 22*57984Sbostic 23*57984SbosticSome other problems: 24*57984Sbostic You may see warning messages about illegal pointer combinations. 25*57984Sbostic It's because systems prototype malloc, calloc and realloc in 26*57984Sbostic different places. If you want to stop the warnings, find out 27*57984Sbostic where your system prototypes them, and include it in compat.h, 28*57984Sbostic or, just prototype them yourself. 29*57984Sbostic 30*57984Sbostic The dbopen(3) routines also use the snprintf(3) function. If 31*57984Sbostic you don't have this function, change the snprintf() call in 32*57984Sbostic btree/bt_open.c:tmp() from snprintf() to sprintf(), making sure 33*57984Sbostic to delete the SECOND argument, the size of the buffer. 34*57984Sbostic 35*57984SbosticTo install: 36*57984Sbostic Programs using the dbopen(3) interface have to include db.h. 37*57984Sbostic To install the library, you'll need to put db.h (found in the 38*57984Sbostic directory PORT/include) and the library libdb.a in some place 39*57984Sbostic accesible to your program. 40
