configure: error: db not installed or functional
I'm using db4 version 4.8.30, and db4-devel package is installed. I can
compile RC1 without any errors.
When I try to compile this test file that configure generates:
/* confdefs.h */
#define PACKAGE_NAME ""
#define PACKAGE_TARNAME ""
#define PACKAGE_VERSION ""
#define PACKAGE_STRING ""
#define PACKAGE_BUGREPORT ""
#define PACKAGE_URL ""
#define STDC_HEADERS 1
#define HAVE_SYS_TYPES_H 1
#define HAVE_SYS_STAT_H 1
#define HAVE_STDLIB_H 1
#define HAVE_STRING_H 1
#define HAVE_MEMORY_H 1
#define HAVE_STRINGS_H 1
#define HAVE_INTTYPES_H 1
#define HAVE_STDINT_H 1
#define HAVE_UNISTD_H 1
#define SIZEOF_LONG 8
#define HAVE_LIBCRYPT 1
#define HAVE_MALLOC 1
#define HAVE_REALLOC 1
#define HAVE_CALLOC 1
#define HAVE_FREE 1
#define HAVE_LIBEXPAT 1
/* end confdefs.h. */
/* Override any GCC internal prototype to avoid an error.
Use char because int might match the return type of a GCC
builtin and then its argument prototype would still apply. */
#ifdef __cplusplus
extern "C"
#endif
char db_create();
int
main ()
{
return db_create();
;
return 0;
}
I got this linking error:
$ x86_64-pc-linux-gnu-gcc -o conftest -mtune=generic -march=x86-64 -ldb -
lexpat -lcrypt db.c
/tmp/cc6Q7xex.o: In function `main':
db.c:(.text+0xa): undefined reference to `db_create'
collect2: ld returned 1 exit status
In libdb.so, there is no such symbol like db_create, but db_create_4008 exists
and in db.h header file db_create is defined as a macro:
#define db_create db_create_4008
So, checking db_create function with AC_CHECK_FUNC is wrong for DB 4.8. I
think db.h must be included to use db_create method but the file generated by
autoconf just tries to use db_create function which is not available if db.h
is not included.
When I apply the workaround attached I can pass configure now, but I know this
is not the right solution. I think this patch must be reverted until it is
tested with all db versions.
