i tried the following with 1.71.17

Code:

  library kernel32,'KERNEL32.DLL',\
          libgtk-3-0,'libgtk-3-0.dll'

include 'API\KERNEL32.INC'
import libgtk-3-0,\
        gtk_about_dialog_add_credit_section,'gtk_about_dialog_add_credit_section'

D:\PROJECT>fasm greminder.asm

greminder.asm [22]:
library kernel32,'KERNEL32.DLL',\
D:\fasmw17117\INCLUDE\macro/import32.inc [9] library [4]:
if defined name#.redundant
error: invalid name.

if clear the '-' dash, "import libgtk-3-0" change to "import libgtk"
it assembled fine.

is it no dash allowed for import library naming?

It is just a standard label name with the same naming restrictions as any other label name. Use an underscore, or something, instead.

now i change it back, it doesn't assemble anymore, weird, sometime it works, sometime it doesn't.

Code:

format PE GUI 4.0
entry start

include 'win32a.inc'

section '.data' data readable writeable
apple   dd 0

section '.code' code readable executable
start:
        invoke  ExitProcess,0

section '.idata' import data readable
  library kernel32,'KERNEL32.DLL',\
          libgtk,'libgtk-3-0.dll'

include 'API\KERNEL32.INC'
import libgtk,\

        gtk_about_dialog_add_credit_section,'gtk_about_dialog_add_credit_section'

weird,i copied from notepad, there is no CRLF between libgtk,\ to gtk_about....
but once i paste it here, there got CRLF, maybe issue with notepad i guess.

2 CR there? 0D 0D
maybe i did something wrong with the dll2inc, i guess.

but i didn't put two 0D 0D

sleepsleep

Code:

cinvoke fopen,oufwrite,<'wb+',0>

must use b, binary, otherwise, fprintf seems to add another 0x0D into buffer.

sleepsleep,

Yep, C runtime writes '\r\n' instead of each '\n' for files opened in text mode. This is platform-specific issue, because historically end-of-line is represented as CR LF pair in DOS and Windows; thus text streams use that translation internally during input/output.

Perhaps you would be better off to use the Windows native functions (WriteFile etc.) for such things.
