description |
NIH uses the __abort_msg symbol to save a string explaining why nih_assert() failed. However, __abort_msg is not a public symbol which causes problems when libc is upgraded - it actually necessitates that for every libc upgrade on, for example, Ubuntu systems the following has to happen:
1) eglibc is upgraded with a version set to <version>~foo
2) nih is rebuilt against the eglibc version
3) nih is upgraded.
4) the eglibc package is upgraded *again* to drop the ~foo.
The symbol can be made use of like this:
$ cat >foo.c<<EOF
int
main(int argc, char *argv[])
{
nih_log_set_priority (NIH_LOG_FATAL);
nih_assert (0 == 1);
exit (EXIT_SUCCESS);
}
EOF
$ gcc -std=gnu99 -g -Wall -pedantic -o foo foo.c `pkg-config --cflags --libs libnih`
$ ./foo
(null):nih_make_core.c:46: Assertion failed in main: 0 == 1
Aborted (core dumped)
