Bug ID: 87710
Summary: Explicitly mentioned libraries by -lx are not in the
DT_NEEDED list
Product: gcc
Version: 7.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dilyan.palauzov at aegee dot org
Target Milestone: ---
Calling “make install” without DESTDIR after building libc-2.28 calls
eventually glibc-2.28/srcribts/test-installation.pl . It creates the file
test-prg7044.c with content:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
printf ("Your new glibc installation seems to be ok.\n");
exit (0);
}
Then calls “gcc /src/glibc228/test-prg7044.c -lc -lBrokenLocale -lpthread
-lcrypt -ldl -lgcc_s -lnsl -lutil -lnss_dns -lnss_compat -lmvec -lresolv
-lnss_db -lm -lnss_files -lrt -lnss_hesiod -lanl -o
/src/glibc228/test-prg7044“, and chechs whether „ldd test-prg7044” contains
BrokenLocale. On my system the comman above invoked with -v prints:
Using built-in specs.

Since libBrokenLocale and others are not listed by ldd, test-installation.pl
fails.
Neither -fuse-ld=gold nor -Wl,--no-as-needed do have any impact.
