Hi, I meet a problem about link, the error message is as the following:
...
ld:warning:symbol 'xxxx' has differing size:
(file /xxxxxx/libBuild.a(aaa.o)value = 0x4; file /xxxxxx/libBuild.a(bbb.o)value = 0x10);
/xxxxxx/libBuild.a(bbb.o) definition taken
...
What does it mean? Especially the "definition taken"!
Thanks!
