Бага исправлена, можно спокойно линковать.
Обнаружилась ещё одна типичная проблема, которую легко понять на
приведённом ниже простом примере:
$ cat libfoo1.c
int foo1(void) { return 0; }
$ cat libfoo2.c
extern int foo1(void);
int foo2(void) { return foo1(); }
$ cat foo3.c
extern int foo2(void);
int main(void) { return foo2(); }
$ gcc -Wall -fpic -shared libfoo1.c -o libfoo1.so
$ gcc -Wall -fpic -shared libfoo2.c -o libfoo2.so -L. -lfoo1
$ gcc -Wall foo3.c -o foo3 -L. -lfoo2
/usr/bin/ld: warning: libfoo1.so, needed by ./libfoo2.so, not found (try using -rpath or -rpath-link)
./libfoo2.so: undefined reference to `foo1'
collect2: ld returned 1 exit status
$ gcc -Wall foo3.c -o foo3 -L. -lfoo2 -Wl,-rpath-link,.
Тонкость в том, что раньше ещё и так работало (хоть и ругалось):
$ gcc -Wall foo3.c -o foo3 -L. -lfoo2 -lfoo1
/usr/bin/ld: warning: libfoo1.so, needed by ./libfoo2.so, not found (try using -rpath or -rpath-link)
А теперь так не работает:
$ gcc -Wall foo3.c -o foo3 -L. -lfoo2 -lfoo1
/usr/bin/ld: warning: libfoo1.so, needed by ./libfoo2.so, not found (try using -rpath or -rpath-link)
./libfoo2.so: undefined reference to `foo1'
collect2: ld returned 1 exit status
Я пока что не знаю, это фича или нет. Скоро ситуация прояснится.
