Help with SCons

[neil_1]

i've been trying to compile this program and have been getting errors.
could someone tell me if i'm missing any dependencies ?

http://www.assembla.com/code/nixcoders/subversion/nodes/qvmkanker/trunk?rev=75 (http://trac.assembla.com/nixcoders/browser/qvmkanker/trunk?rev=8&order=name)

the output i have is

There was a gcc include file sort out round about version 4.3 (i think), these errors are examples of older code relying on include files being automatically added where they now need to be added manually. If remembered correctly,
uint32_t means you need <stdint.h>
EXIT_FAILURE means you need <cstdlib>
I'll try and find the list of common errors

[SevenMachines]

See http://gcc.gnu.org/gcc-4.3/porting_to.html section 'Header Dependency Cleanup' for the most common ones

[neil_1]

Thanks for that SevenMachines
I've added the headers needed and most of the errors went away apart from one.
i get a


libqvm/Qvm.cpp:54: error: 'strerror' is not a member of 'std'
when i try to compile.
if i remove the "std::" before the strerror, i get a lot of the same error


libqvm/vm.cpp:215: error: deprecated conversion from string constant to 'char*'
and at that particular line, there is no conversion at all.

i've uploaded the updated code if you could point me in the right direction.

[SevenMachines]

I think
#include <cstring>

[neil_1]

I think
#include <cstring>
still have the same error
libqvm/vm.cpp:215: error: deprecated conversion from string constant to 'char*'

the error lies on the last line of this piece of code

};//error is on this line (though i know it's probably not this)
i don't understand why though

[SevenMachines]

Thats a slightly different if similarly age related error, the error is more 'newish' gcc stuff.
"something" is a string const, but the array is declared 'char *', which isnt const. You should declare a const char * array here, be warned you may (probably) end up chasing through the code following a ripple of const correct changes though. If you want to fix it properly then thats what to do.
If you just want to ignore the warning and keep going it'll probably be fine :) then add
'-Wno-write-strings' to your CFLAGS in SConstruct, which hopefully should be in there somewhere. Hopefully thats all fairly accurate :)

[neil_1]

That did it!
Thanks a bunch SevenMachines!
