Bug 903689 – =dev-scheme/guile-ssh-0.16.3 fails to build on clang: log.c:98:10: error: call to undeclared function 'backtrace'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sergei Trofimovich 2023-04-02 07:20:10 UTC]

On default/linux/amd64/17.1/systemd/clang/merged-usr profile 'guile-ssh' fails to build as:

# emerge -v1 guile-ssh

log.c:98:10: error: call to undeclared function 'backtrace'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  size = backtrace (array, STACK_BUF_SZ);
         ^
log.c:99:13: error: call to undeclared function 'backtrace_symbols'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  strings = backtrace_symbols (array, size);
            ^
log.c:99:11: error: incompatible integer to pointer conversion assigning to 'char **' from 'int' [-Wint-conversion]
  strings = backtrace_symbols (array, size);
          ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It's caused by an invalid files/guile-ssh-0.16.0-musl.patch added in https://bugs.gentoo.org/877721:

It removes `#include <execinfo.h>`. But that header's symbols are being used in log.c.
