Compiling Win64 Windows DLL

[Dennis Hoskins]

Paul,

I am trying to compile a 64-bit windows dll. I copied the following from the FB manual:

Code Select Expand


'' mylib.bas
'' compile with: fbc -dll mylib.bas

'' Add two numbers together and return the result
Public Function Add2( ByVal x As Integer, ByVal y As Integer ) As Integer Export
  Return( x + y )
End Function

When I compile, I get 1 error but no indication of the error:

The compiler command line is:

The build configuration is:

I have tried with -s console and without.

Any suggestions to find the error?

Thank you,

Dennis

Hi Dennis, that's odd because it worked perfectly for me on the first shot. Here is all I did:

- Start WinFBE64
- New file (saved it as testdll.bas)
- Pasted in your code from your post above.
- Selected "Win64 Windows DLL" from the droplist in the top toolbar.
- Pressed compile.

It produced a 20K dll.

Can somebody else here try this test to see if they run intot he same issue as Dennis has?

Also, are regular EXE type of programs compiling for you in both 32 and 64 bit? Is it only the DLL's that are showing this problem?

did the same for me - got 20Kdll  (and i've never created one b4)

Hello Dennis

I can't confirm your mistake, too.
My result is concruent with Paul and raymw.

[Paul Squires]

It "could be" related to the fact that you have WinFBE installed into a folder that has a space in it (WinFBE Suite vs. WinFBE_Suite). This has caused problems in the past with the interaction between CreateProcess and GCC. I check for embedded spaces folder paths (even enclosing the path in double quotes doesn't seem to help) and then use an alternate compile process via batch files. Try moving your installation to a folder without spaces to see if that is the problem. It's worth a shot.

I haven't used WinFBE much at all in the past, but in previous versions I have compiled some of the example programs without problem. To install I copy the files from the .rar file to C:\Software\WinFBE Suite.

I tried to compile the following code from powershell

Code Select Expand


Print "Hello World"
Print "Press any key ..."

Thank you Paul,
The space in the folder name was the problem.
Functioning now.
