During an exp-run for llvm 15 (see bug 265425), it turned out that
archivers/rpm4 failed to build with clang 15:
tools/rpmuncompress.c:101:23: warning: call to undeclared function 'basename'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
const char *bn = basename(fn);
^
tools/rpmuncompress.c:101:18: error: incompatible integer to pointer conversion initializing 'const char *' with an expression of type 'int' [-Wint-conversion]
const char *bn = basename(fn);
^ ~~~~~~~~~~~~
This is because basename(3) is defined in <libgen.h>. After this include
is added to rpmuncompress.c, link errors still occur:
ld: error: undefined symbol: WIFEXITED
>>> referenced by rpmuncompress.c
>>> tools/rpmuncompress.o:(main)
ld: error: undefined symbol: WEXITSTATUS
>>> referenced by rpmuncompress.c
>>> tools/rpmuncompress.o:(main)
This is because WIFEXITED() and WEXITSTATUS() are macros defined in
<sys/wait.h>.
