Re: How to eliminate the cmd.exe windows when lyx starts?

[Bo Peng]

Anybody know why a cmd.exe window is used when lyx starts?

OK. Answer my own question:

I have confirmed that if I add the attached wrapper to the main()
function in main.C, and add /subsystem:windows to scons/LINKFLAGS, lyx
would no longer be a console application, and start without the
command window. The wrapper is borrowed from
http://www.flipcode.com/cgi-bin/fcarticles.cgi?show=63933 .

Is there a general interest in this? Lars may not like #ifdef WIN32 in
main.C, some minor (?) autotools adjustment is also needed.

Cheers,
Bo
