Bash not accepting DOS line endings

MTsoul · 2008-12-01 07:17:10

Hi,

I'm trying to build the Boost C++ library. However, its configure scripts (hundreds of them) are filled with inane DOS line endings, and bash is not reading it correctly. It outputs things like "line 2: $'\r' command not found'. Is there a way to make bash accept it or ignore it?

Thanks in advance.

You might try automatically converting the file with the 'dos2unix' tool from the 'hd2u' package.

or ...

cat dos-file | tr -d '\r' >unix-file

Not practical. In a package of thousands of files, I do not know which are shell scripts, and there are hundreds of them...

Is there a way to make \r an alias of nothing? I tried doing it, but bash complains that \r is not a valid alias..

Sounds like you need to use some "find ... -exec sed ..." magic.

What do some of these files look like? I guess I'm just a little confused because the boost c++ sources that I'm looking at don't resemble what you're describing at all, so I'm not sure which boost c++ libs you're trying to build. I guess you could do this:

$ find /path/to/source -type f -exec dos2unix {} \;

It has C++ sources, but to build them into libraries, its configure scripts are shell scripts, and they are located across the library.

How well does that work ^? There are binaries in the package.

How about you simply modify the PKGBUILD? Why do you want to compile yourself in the first place?

I have some special needs for the binary.

Turns out they distribute Windows and Unix packages differently. I downloaded the .zip version, which is Windows even though they say it's cross-platform. Big d'oh! Thanks for all the help guys.
