Hi,
I compiled VIM on my home machine over the weekend and got a few warnings:
misc2.c(6277) : warning C4244: '=' : conversion from 'long_u' to 'int',
possible loss of data
undo.c(828) : warning C4267: '=' : conversion from 'size_t' to 'int',
possible loss of data
undo.c(1630) : warning C4311: 'type cast' : pointer truncation from
'u_header_T *' to 'long'
undo.c(1635) : warning C4311: 'type cast' : pointer truncation from
'u_header_T *' to 'long'
undo.c(1640) : warning C4311: 'type cast' : pointer truncation from
'u_header_T *' to 'long'
undo.c(1645) : warning C4311: 'type cast' : pointer truncation from
'u_header_T *' to 'long'
At home I am using:
VC 2005 Express
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 14.00.50727.762
for 80x86
Build command I am using is:
nmake -f make_mvc.mak GUI=yes POSTSCRIPT=yes PYTHON=e:\python26
PYTHON_VER=26 DYNAMIC_PYTHON=yes
What is odd is that with the same sources and build line I don't get
these warnings on my work machine. The difference is that that is using
a commercial version of VC 2005. Ah, for some reason the 64 bit
warnings are not being enabled - do that and I do get the above
warnings. The warnings in undo.c indicate code that will cause errors
with Windows 64 bit builds - uh_seq should be an intptr_t or whatever
the final decision was on type name for 64 bit integers that can hold
pointer values.
I'll work on a patch for the makefile to ensure the 64 bit warnings get
produced in both the Express and full versions of VC8 - unless someone
else gets there before me.
TTFN
Mike
