完全新手,初學(xué)中。通過更改例程編寫上位機傳幾個數(shù)據(jù)至USB中,編譯正常,組建鏈接出現(xiàn)如下問題:
Linking...
DataTest.obj : error LNK2001: unresolved external symbol _CH375CloseDevice@4
DataTest.obj : error LNK2001: unresolved external symbol _CH375WriteData@12
DataTest.obj : error LNK2001: unresolved external symbol _CH375SetTimeout@12
DataTest.obj : error LNK2001: unresolved external symbol _CH375OpenDevice@4
Debug/DataTest.exe : fatal error LNK1120: 4 unresolved externals
執(zhí)行 link.exe 時出錯.
DataTest.exe - 1 error(s), 0 warning(s)
想問問是什么問題?謝謝!
