To test why I can't compile my driver using Paladin I first created the
smallest none working version of the driver.

And this is the makefile settings I used to compile the driver from the
terminal.

This is a result reported in the terminal from using the makefile, the driver
did compile ok.

following.

When I choose the BUILD->MAKE
option in the menus I get the following error,
#########################################################################
/boot/system/develop/lib/start_dyn.o: In function `_start':
start_dyn.c:(.text+0x57): undefined reference to `main'
collect2: ld returned 1 exit status
#########################################################################
Then when I examined the project settings found that while I created a 'Driver'
project that Paladin reported it as an
'Application' project. Selecting a 'Driver' project again the .PLD file had one
change made.
#########################################################################
CCTARGETTYPE=3
#########################################################################
The BUILD->MAKE
gives the following error,
#########################################################################
gcc: /boot/develop/lib/x86/_KERNEL_: No such file or directory
#########################################################################
Note: I also tried the above builds with a '.cpp' extension. They still failed
the same way.
Now the _KERNEL_ error is one I saw before when Haiku first changed it's file
structure to support PM, the way I got
around it was to copy the 'develop' folder into the ROOT. However after I
copied the folder to the root '/boot' a lot
of the links were broken. I fixed this by copying over the files original
pointed to, I also copied _KERNEL_ to the
'x86' folder and once again tried to build the driver with Paladin, This time
I got a different error:
#########################################################################
/boot/system/develop/lib/start_dyn.o: In function `_start':
start_dyn.c:(.text+0x57): undefined reference to `main'
collect2: ld returned 1 exit status
#########################################################################
Can anyone make any suggestions.
