If $static is 'yes' then calling $pkg_config already passes the --static flag (see $QEMU_PKG_CONFIG_FLAGS). You probably just want to always do the compile_prog, rather than special-casing $static=yes. See also the gnutls_works function which is doing a similar "ask pkg_config, but sanity check that it compiles" job. (We could maybe abstract the idea out into a 'pkg_exists_and_works thing' function, but I'd be happy to wait til we have 3 uses before doing that.) PS: this is a bug in Fedora, which is shipping bogus pkg-config info for the static case. thanks -- PMM
