The customer is having problems when their "*.l" files are in dos format. Flex is taking the lines from the file and adding them into the lex.yy.c file untouched. (i.e. they still have the \n\r at the end), and this causing problems later on.
I tried using the version of flex that comes with the latest version of cygwin (1.5.12) and flex changes the \n\r to just \n, which makes everything work fine. Good I thought since the version of flex we provide is not the latest. I'll just recompile.
But when I tried that with the latest flex (2.5.4a-3) I get the same behavior that the customer is seeing. I get this behavior even if I compile on the latest version of cygwin.
So, my question is what options are used for building flex?
there's no build script and an inactive maintainer. we don't know. hopefully just the standard options.
./configure --prefix=/usr sharedstatedir=/var --mandir=/usr/share/man
make && make installThe filesystem has been mounted in binmode, but the flex that comes with cygwin translates the files. Both flex and the text file are on binmode mounts.
Linking against /usr/lib/binmode.o perhaps?
He meant that by accident flex was linked against binmode.o, which is wrong. It was no advice to reproduce that error with linking against binmode or textmount.
Tried on cygwin 1.5.12 make clean make LDFLAGS="/usr/lib/binmode.o",
and make clean make LDFLAGS="-lbinmode"
but neither helped
for sure not.
However linking the /usr/lib/textmode.o did work make LDFLAGS="/usr/lib/textmode.o" # <- did the job Thanks Larry for pointing me in the right directory :)
Oh god. This was the right direction? Sorry no.
If you open your flex input file in a *textmode mount* \r\n will get converted, if you open that in a binmode mount it will not get converted.
$ man mount
ok thanks, for confirmation. so cgf should repackage it. it's obviously a bug.
And please add a hint how to reproduce from source, so we don't have to guess. Christofer claims that he didn't link against textmode.a, but it looks like so, or there was some deeper magic behind, which went away suddenly.
He is using automode.o, he said in one of the followups to this thread.
Hint should be included in original posting. It has original make commands that I used plus a simple example for testing. It also has instructions on how to build and run the simple sample
Modified build commands would be ./configure; make LDFLAGS="/usr/lib/automode.o"
