How do I use an "o" file?

[JimKueneman]

I am working on converting this:

https://github.com/signal11/hidapi

When I run the make file in the mac folder I get an "hid.o" file.  Once I get the C header file translated to pascal what do I do to link in the "hid.o" file and call a function in the pascal translated file?

Code: [Select]

{$L thatfile.o}Note the object file format (differs per platform AFAIK) and all other things that it uses, including but not limited to standard C library.

Thanks I found that.  As you said I am getting a

ld: warning: ignoring file hid.o, file was built for unsupported file format ( 0xCF 0xFA 0xED 0xFE 0x07 0x00 0x00 0x01 0x03 0x00 0x00 0x00 0x01 0x00 0x00 0x00 ) which is not the architecture being linked (i386): hid.o

Error.  I built the hid.o file on the machine I am running Lazarus.

The error message is clear. You did read my warning, didn't you? Where you build the .o is not a problem, but HOW you build it could be the problem.
