hi,
It looks like I am pretty unlucky with this so, it is quite likely I
have missed something important. Help would be welcome.
mathieu@mathieu:~/code$ cat test.c
void test (void)
{}
mathieu@mathieu:~/code$ cat test.map
A {
global:
test;
local:
*;
};
B {
global:
test;
} A;
mathieu@mathieu:~/code$ gcc -O0 -g -fpic -c test.c -o test.o
mathieu@mathieu:~/code$ gcc -shared -Wl,--version-script=./test.map
./test.o -o test.so
mathieu@mathieu:~/code$ readelf -V -s ./test.so |grep test
5: 0000039c 5 FUNC GLOBAL DEFAULT 12 test@@A
48: 00000000 0 FILE LOCAL DEFAULT ABS test.c
62: 0000039c 5 FUNC GLOBAL DEFAULT 12 test
000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: test.so
mathieu@mathieu:~/code$
The above shows that test is exported under version 'A' as the default
symbol. I was expecting instead something like that (imaginary
output):
5: 0000039c 5 FUNC GLOBAL DEFAULT 12 test@A
5: 0000039c 5 FUNC GLOBAL DEFAULT 12 test@@B
which would indicate that symbol test is exported under both version A
and B and that B is the 'default' version. What step did I miss to get
this result ?
