      Push $0
      Push $1
      Push $2
      Push $3
      Push $4
      Push $6

      FindWindow $0 "#32770" "" $HWNDPARENT

        Pop $3
        StrCpy $2 0
        System::Call "*(i, i, i, i, i, i, i, i, i) i \
          (0, 0, 0, 0, 0, r3, ${NSIS_MAX_STRLEN}) .r1"
        loop: StrCmp $2 $6 done

          System::Call "*$3(&t${NSIS_MAX_STRLEN} .r4)"
          FileWrite $5 "$4$\r$\n"
          IntOp $2 $2 + 1
          Goto loop

来自 nsis website ，我得到错误

lvm_getitemcount already defined 

编译安装程序脚本时。有任何想法吗？

Answer 1

编译器告诉你这个问题!

其他一些代码已经定义了该符号，可能在您包含的标题中。

注释掉第二个定义或检查它是否已经被定义:

!ifndef LVM_GETITEMCOUNT 
!define LVM_GETITEMCOUNT 0x1004
!endif
!ifndef LVM_GETITEMTEXT 
!define LVM_GETITEMTEXT 0x102D
!endif
