Compiling on cygwin

Compiling on cygwin

[Ben Pazolli]

I can't get insight to compile on cygwin so I can run insight on
windows. I can do ./configure but when I run make it always exits with
messages like '...pex-unix.c:518: error: 'F_SETFD' undelared...'
'...pex-unix.c:518: error: 'FD_CLOEXEC' undeclared...' '...make[2]:
*** [pex-unix.o] Error 1...' and '...make[1]: ***[all-libiberty] Error
2...'. Any Ideas? I am using the standard installation of cygwin and
added the mingw installation and the gmp. I really really want to
compile this.

I don't often test on cygwin, but I know I compiled it on that platform 
a couple of months ago when I did the big configury overhaul.

Nonetheless, you are having problems with libiberty with some standard 
defines missing... Either there is a compiler flag which is wrong or you 
are missing some required software (like a library)... You might want to 
ask on a more cygwin/mingw savvy mailing list than this one. [Have you 
tried doing a web search?]

Otherwise, it would be helpful to have the complete output of configure 
and make.

Okay, from this, I can tell a few things... First of all, it looks like 
you want to build for cygwin. However, the linker that configure grabbed 
was for mignw. You are also missing bison, and that is required to build 
(unless you've grabbed a release tarball). So may some sort of lex 
variant. I don't recall at the moment.

If you intend to build for cygwin, you must make sure that cygwin tools 
are in your PATH ahead of mingw. If you are attempting to build for 
mingw (which I'm pretty sure will not work very well w/Insight -- it 
assumes windows means cygwin), you need to specify to configure that you 
are building for mingw (--target=i686-pc-mingw, I think).

I know gdb has had some churn in it in the past year to add "native" 
mingw support, but I don't believe that this will work with Insight. I 
have never tried, though, so it might not be as bad as I am guessing.

just for info insight-6.8 builds on native mingw out of the box.
older versions of insight required a few tweaks however.

Excellent, thank you for letting me know! I've only ever used cygwin, 
and that's that platform that I usually check for windows -- I have a 
*very* old windows 2000 machine that I check insight builds on.

Spen,
If you monitor this list maybe you can answer this. When you say "builds 
on native mingw" do you mean under cygwin with configure option CC="gcc 
-mno-cygwin" or do you mean builds under the msys shell?

So far I have gotten errors with both methods with CVS head version. 
Haven't tried 6.8 yet.

Trying pure cygwin build now...
