libewf build error with clang

[macsforever2000@…]

I'm seeing the following build error for libewf on Mac OS X 10.7.2. Xcode 4.2.1.

I see you're using clang. Have you tried using a different compiler?

Another idea: I see newer alpha and beta versions are available. You could try one of those, and if they work, maybe we can identify what change fixed this problem and backport it to the stable version.

[ranauei@…]

This seems the same error I had with minidlna. It's about the use of inline wich is interpreted differently between clang (C99) and gcc (GNU89). See here ​http://clang.llvm.org/compatibility.html#inline I attached a possible fix. If other files trip this error simply proceed in the same manner.

Possible fix to compile with clang

[ranauei@…]

I just tested the port with the patch and it compiles fine with clang. Since I was there I fixed other things in the Portfile. Mainly the style wich was in a really bad shape, also I moved checksums to sha256/rmd160 and fixed master_sites (the strange thing with the certificate and removed the other url, I think sourceforge is enough).

[ranauei@…]

Added patch and fixed style and few other things.

[ranauei@…]

Cc Me!

[ranauei@…]

Just the minimum changes

[ryandesign@…]

Thank you for attaching a minimal patch; we don't want to mix whitespace changes with other changes.

Why increase the port's revision? This won't change the files that get installed by the port, will it? People using clang won't have been able to install it before at all, and people not using clang would get exactly the same files as before.

[ranauei@…]

Replying to ryandesign@…:

Why increase the port's revision? This won't change the files that get installed by the port, will it? People using clang won't have been able to install it before at all, and people not using clang would get exactly the same files as before.

Because I think there is the slightly chance that someone installed this port anyway manually modifying it, for example forcing another compiler, without filing a ticket.

Maintainer timeout.

• r88471: fixed build with clang
• r88472: removed broken uitwisselplatform.nl master_sites entry
• r88473: removed code that does nothing
