Rename truncate() to sac_truncate(). There are a couple places (2?) in the src/sss/xtraveltime.c that need to be renamed.

Hi Brian,

That did the trick. I used ./configure --enable-readline and it used -lreadline. It got me much further. Now, it looks like there is a function in sss/xtraveltime.c already contained in stdio.h conflicting:

gcc -DHAVE_CONFIG_H -I. -I../inc -I/usr/local/include -D_THREAD_SAFE -pthread -I../inc -c -o sss/xtraveltime.o sss/xtraveltime.c
sss/xtraveltime.c:31:1: error: conflicting types for 'truncate'
truncate(char *s) {
^~~~~~~~
In file included from sss/xtraveltime.c:2:
/usr/include/stdio.h:441:6: note: previous declaration of 'truncate' was here
int truncate(const char *, __off_t);
^~~~~~~~
*** Error code 1

Just to test, I commented out that include and I got this:

gcc -DHAVE_CONFIG_H -I. -I../inc -I/usr/local/include -D_THREAD_SAFE -pthread -I../inc -c -o sss/xtraveltime.o sss/xtraveltime.c
sss/xtraveltime.c:31:1: error: conflicting types for 'truncate'
truncate(char *s) {
^~~~~~~~
In file included from ../inc/sss.h:11,
from sss/xtraveltime.c:7:
/usr/include/stdio.h:441:6: note: previous declaration of 'truncate' was here
int truncate(const char *, __off_t);
^~~~~~~~
*** Error code 1

Commenting iut the include in inc/sss.h resulted in:

gcc -DHAVE_CONFIG_H -I. -I../inc -I/usr/local/include -D_THREAD_SAFE -pthread -I../inc -c -o sss/xtraveltime.o sss/xtraveltime.c
In file included from sss/xtraveltime.c:7:

../inc/sss.h:328:17: note: 'FILE' is defined in header '<stdio.h>'; did you forget to '#include <stdio.h>'?
../inc/sss.h:14:1:

../inc/sss.h:328:17:

^~~~~~~~

So it looks like this funcion is used in these header files too. I'm not sure how to fix this. How do you think I should proceed?

Thanks again.

Jonathan,

If you turn off the edit line library, or use the version provided with FreeBSD that would be a workaround.

I think doing something like
% ./configure ?enable-readline
should work, or
% ./configure ?disable-editline

The editline lib is originally from NetBSD, so there is a good possibility it should work,

Hi All,

I'm on FreeBSD 12 using gcc8. I'm receiving some errors during compile
that might be due to changes in gcc8 from pervious versions. It might be
an old version of libedit with gcc8 causing the issue:
