Gold does not seem to handle implicit shared library dependencies. The
following test case fails:
bar.c:
------
int bar() {
return 0;
}
foo.c:
------
extern int bar();
int foo() {
return bar();
}
app.c:
------
extern int foo();
extern int bar();
int main(int argc, char *argv[]) {
foo();
bar();
}
Sequence of commands to reproduce:
----------------------------------
gcc -c -o app.o app.c
gcc -fpic -c -o foo.o foo.c
gcc -fpic -c -o bar.o bar.c
ld -shared -olibbar.so bar.o
ld -shared -olibfoo.so -L. -lbar foo.o
gcc -o app -Wl,-rpath,. -L. -lfoo app.o
Output:
-------
/usr/bin/ld: app.o: in function main:app.c(.text+0x1f): undefined reference to
'bar'
collect2: ld returned 1 exit status
Reference:
----------
This example works perfectly with the old linker.
