C Header to .bi

[Dinosaur]

Hi All

I haven't followed the progress on this subject for many years, but do recall a member
writing a program called h_2_bi.
I have tried every search term in my Jurassic brain but can't get a hit.

Does anyone know of an updated solution or a link to the OP.?

Regards

hello Dinosaur
you find h_2_bi at https://www.freebasic-portal.de/downloa ... s-134.html
I use fbfrog by dkl https://github.com/dkl/fbfrog

Hi All

Thanks srvaldez,
I don't know how you find that so quick, but the search facility on the FB Forum frustrates me.
Why can't i simply search for ONE word "h_2_bi".

Either way, fbfrog does the trick nicely.

You can search with google, it usually gives results:

Hi All

Using FBFrog on a .h file creates lots of "Not Found" .h files.

For example

emitting: libaiousb.bi (2511 declarations, 92 TODOs)

I have added the

./fbfrog -incdir /usr/include libaiousb.h

The missing .h files seem to have their paths incorrectly specified.
Like:
bits/waitflags.h (not found)
Should be:
/usr/include/x86_64-linux-gnu/bits/waitflags.h

How do you normally handle this kind of problem ?
Do you correct the path in the source .h file or do you copy the .h file to another folder.
If correcting the path, how do I know which .h file to find the statement in ?

Hi All

I have one issue with a number of C Functions that I don't understand.
The Functions are typically declared as per:

unsigned long AIOUSB_Init()

I then write a small test program as such:

Code: Select all

Extern "C"
    Extern AIOUSB_Init() Alias "AIOUSB_Init()" As Longint
    Extern AIOUSB_ListDevices() Alias "AIOUSB_ListDevices()" As Longint
End Extern
Dim au As Longint
au = AIOUSB_Init(0)
Print au

The error I get is as follows:

/home/barfresh/projects/aiousb/AIOTest.c:40:27: error: lvalue required as unary ‘&’ operand
AU$0 = *(int64*)*(int64*)&AIOUSB_Init();
^

There are descriptions relating to this problem for C/C++ but can't find anything usable in FreeBasic.

You state that the original C prototype is unsigned long AIOUSB_Init(), which takes no arguments, but then you go on to try to call it with 0 as an argument. Is there something missing there?

Anyway your declarations are not correct. try something like:

Code: Select all

Extern "C"
    declare Function AIOUSB_Init Alias "AIOUSB_Init" () As Longint
    declare Function AIOUSB_ListDevices Alias "AIOUSB_ListDevices" () As Longint
End Extern

Hi All

caseih, I was aware of that, but tried dozens of different ways to call the function
to get rid of the error.
