Hi, I'm looking at moving a c/c++ project from Linux to Windows. One of
the things we have in the linux version is an xml file that is parsed
by a custom perl script to generate a .c and .h file that contains
configuration structures.
This xml file contains default values for attributes that are actual
#defines in other header files in the project. As a result we parse the
.xml file with the c preprocessor 'cpp'. Then throw the resulting .xmlp
file into our perl script.
How could this preprocessing step be accomplished in visual studio
2003?? Is its preprossor able to parse and xml file or is there a win32
equivalent of cpp.
Thanks
There are at least two options that I know of... The one that immediately
jumps to mind is to install Cygwin and just use cpp. However, I believe
that you can do this with VS (I used VS.NET 2003). I created a text file
named temp.txt...
<temp.txt>
#define test TEST THAT WORKED
This is a test
</temp.txt>
Then I ran the VC compiler with the following command line...
<command>
cl /nologo /EP /C temp.txt>output.txt
</command>
In case you're not familiar with VS, those parameters are...
/nologo - don't display the compiler logo
/EP - pre-process to stdout with no #line's
/C - don't strip comments
The contents of output.txt were...
<output.txt>
This is a TEST THAT WORKED
</output.txt>
I've never tried this with VS before, but it appears to work fine. Just for
giggles I changed the source file name to temp.xml to make sure nothing
goofy happened. Also, since I have Cygwin installed, I was able to get the
same results with the command line
<command>
cpp -E -P temp.txt>output.txt
</command>
So it would appear that you can go either way on Windows.
