configure.ac's AC_SEARCH_LIBS([backtrace], [execinfo], ...) fails with 'libexecinfo not found' on musl, which lacks glibc's backtrace()/backtrace_symbols(); depend on the libexecinfo compat library there. Once configure succeeds, ticks.h's timeval2nsec() needs struct timeval, which was only pulled in via <sys/time.h> under __FreeBSD__, and vma-xlio-redirect.cpp calls sscanf()/sprintf() without including <cstdio>; fix both for musl too.

Subject: [PATCH] src: fix missing includes for musl (struct timeval,
|
|
sscanf/sprintf)
|
|
|
|
ticks.h's timeval2nsec() uses struct timeval, but the header only
|
|
pulled in <sys/time.h> under __FreeBSD__ -- glibc's <time.h> happens
|
|
to declare struct timeval as a side effect of other headers already
|
|
included elsewhere in the build, but musl's does not, so building
|
|
against musl fails:
|
|
|
|
| ticks.h:115:30: error: member access into incomplete type 'const struct timeval'
|
|
|
|
Always include <sys/time.h> instead of gating it on __FreeBSD__.
|
|
|
|
vma-xlio-redirect.cpp uses sscanf()/sprintf() but never includes
|
|
<cstdio>, relying on it being pulled in transitively. That doesn't
|
|
happen on musl either:
|
|
|
|
| vma-xlio-redirect.cpp:92:14: error: use of undeclared identifier 'sscanf'
|
|
| vma-xlio-redirect.cpp:99:5: error: use of undeclared identifier 'sprintf'
|
|
|
|
Upstream-Status: Pending
