c++ - Why does gcc "--as-needed" flag cause a missing symbol? - 


g++ [...] -ldiskcache_i [...] -ldcache  [...]

links , runs fine, but

g++ [...] -xlinker --as-needed  -ldiskcache_i [...] -ldcache  [...]

gives missing symbol:

libdiskcache_i.so: undefined reference `tdcachefile::stage(char const*, unsigned int, char const*)'

both of these libraries shared objects.

the symbol requested in -ldiskcache_i , should resolved in -ldcache, before as-needed flag introduced. funny thing method is static method of class tdcachefile, , call uses static property.
