Comment 2 David Carlos Manuelda 2023-06-14 18:42:44 UTC
The problem is that there are _a lot_ of main() instead of int main() -implicit int- and also a lot of exit(X) without including <stdlib.h> in the test in configure scripts.

Thank you!
Comment 4 David Carlos Manuelda 2023-06-16 11:01:30 UTC
I've made 2 patches that makes cdrtools compile with Clang16, yet it still gives a lot of warnings which makes it will fail again in the future, like:

warning: a function definition without a prototype is deprecated in all versions of C and is not supported in C2x [-Wdeprecated-non-prototype]

Will attach them here

Comment 8 David Carlos Manuelda 2023-06-16 11:05:59 UTC
It seems that some more work is needed because mkisofs complains:

mkisofs -o output.iso input_directory
Setting input-charset to 'UTF-8' from locale.
Unknown charset 'UTF-8'.
Known charsets are:
mkisofs: Installation problem: '$INS_BASE/lib/siconv/' missing.

Comment 11 David Carlos Manuelda 2023-06-16 14:07:03 UTC
Good news! With the updated patches (attached) it compiles and (at least mkisofs) runs with clang only!

Please do more test on the other cdrtool binaries
Comment 12 Alec Ari 2023-06-17 12:22:51 UTC
I'm surprised that worked considering this hasn't been merged yet in Clang:

https://reviews.llvm.org/D93031

Does the -fexec-charset CFLAG just get ignored, without erroring out?

commit b8198f022231eabc82e445c8237add7571260303
Author: Sylvestre Ledru <sylvestre@debian.org>
Date:   Mon Aug 11 18:09:03 2014 +0000

    GCC compatibility: Ignore -fexec-charset=UTF-8 argument. It is the default in Clang. Reject other values.

    Summary:
    Just like with -finput-charset=UTF-8 in review http://reviews.llvm.org/D4347, I think we should just ignore it when UTF-8 is provided.

build.log using gcc 14

Building on GCC 14 runs into this as well, applying the patches attached fixes it.

    app-cdr/cdrtools: apply modern C workaround, correctness fixes
    
    * Apply modern C workaround (build with -std=gnu89 for now). No point in trying
      to patch this at least until we're up to date (see bug #672060) which has its
      own complications.
    
    * Filter LTO & pass -fno-strict-aliasing. The code isn't even close to being
      compatible with either.

    app-emulation/virt-manager: allow dev-libs/libisoburn > app-cdr/cdrtools
    
    This commit aims to provide an alternative to the unmaintained cdrtools
    which has all sorts of build failures [1] and [2] and needs patching.
    
    Upstream prefers xorrisofs provided by dev-libs/libisoburn over mkisofs
    which is provided by app-cdr/cdrtools.[3] I had a look at some other
    distros (openSUSE, Fedora and Debian) and they all use xorriso.
    
    The other program that is from cdrtools (isoinfo) has been removed. [4]
