Hello,

I discovered about Tcl just a couple of months ago and I already love
it!
But since I am a new developer I am not very experienced.

I have some problems with a parser of a C++ source code on a Windows
machine.
I developed the code on my Mac and everything works just fine, but
when I execute the same parser on the windows machine it does not
compile.

A simple working example:

set fp [open $::source_file r]
fconfigure $fp -translation auto
set file_data [read $fp]
close $fp

set file_data [regsub {runThreshold = [^;]+;} $file_data
"runThreshold = 0.001;"]

set fp [open $::new_source_file w]
fconfigure $fp -translation auto
puts $fp $file_data
close $fp

This trick creates some problems on the linking phase of a Borland C++
compiler.
If I comment out the line with the regsub the compiler does not
complain.

But if I define the variable runThreshold on a header file and I
include it with the preprocessor it works.

I suspect that there is some problem with the line endings (i.e. CR
and LF) but the fconfigure did not do any good.

Thanks,
Cheru

You don't intend to tell us the exact link error, do you ?
Also, printing out the result of the regsub is one obvious step
towards understanding...

Unfortunately is is a really long source code and I can not post it
because it is not a program of mine.
But I looked for differences between the original and the parsed one
look the same, except for the substitution.
When I will have access to the Windows machine I will save the output
of the compiler.

Thanks,
Cheru
