- Subject: RE:about gcc -XLinker -M
for example,
I want to locate the which lib is linked for fprintf
vvvvvvvvvvvvvvvvv===test.c===vvvvvvvvvvvvvvvvvvvvvvvvv
#include <stdio.h>
main()
{
doit();
}
doit()
{
fprintf(stderr,"==");
}
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I run
gcc -Xlinker -M test.c 2>map
vvvvvvvvvvvvvvvvvvvvv===map===vvvvvvvvvvvvvvvvvvvvvvvvv
...
.plt 0x0804826c 0x30
*(.plt)
.plt 0x0804826c 0x30 /usr/lib/crt1.o
0x0804827c fprintf@@GLIBC_2.0
00804828c __libc_start_main@@GLIBC_2.0
...
^^^^^^I remove some blank for better display
here^^^^^^
rpm -qf /usr/lib/crt1.o
tell me it belong to glibc
But
nm /usr/lib/crt1.o | grep fprint
can't find it.
I also find
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
Archive member included because of file (symbol)
/usr/lib/libc_nonshared.a(elf-init.oS)
/usr/lib/crt1.o (__libc_csu_init)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
at the map file. Is there some information it
indicate?
Thanks for any comment
gan
