When emerging dhcpcd-6.4.2 configure tries to use /usr/bin/x86_64-pc-linux-gnu-clang from llvm-9999 and fails because getifaddrs isn't supported Doing a quickpkg llvm and uninstalling works around the problem - I reinstalled with emerge -G llvm Reproducible: Always

Please attach /var/tmp/portage/net-misc/dhcpcd-6.4.2/work/dhcpcd-6.4.2/config.log (if it exists) and paste emerge --info =net-misc/dhcpcd-6.4.2 as a comment.
1) Please post your `emerge --info' output in a comment. 2) Please attach config.log to this bug report.
I just stumbled across the same problem. The build.log says: Configuring dhcpcd for ... linux Using compiler .. /usr/bin/x86_64-pc-linux-gnu-clang clang version 3.5.0 (tags/RELEASE_350/final) and then it fails: Testing for getifaddrs ... no libc support for getifaddrs is required - aborting

A config.log doesn't exist anywhere in /tmp/portage.

*** Bug 523306 has been marked as a duplicate of this bug. ***
It's a custom configure script, so it doesn't spit config.log. But well, everyone can write a good build system, can't they? :) As for one of the issues, I already pinged WilliamH and suggested to export CC. For the other, we'd need to look what's wrong with the check.
Note that configuring the vanilla package outside of portage, but using the same configure arguments are portage, works just fine: $ ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --libdir=/lib64 --prefix= --libexecdir=/lib/dhcpcd --dbdir=/var/lib/dhcpcd --localstatedir=/var --rundir=/run --enable-ipv6 --with-hook=ntp.conf --with-hook=yp.conf configure args: --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --libdir=/lib64 --prefix= --libexecdir=/lib/dhcpcd --dbdir=/var/lib/dhcpcd --localstatedir=/var --rundir=/run --enable-ipv6 --with-hook=ntp.conf --with-hook=yp.conf Deriving operating system from ... x86_64-pc-linux-gnu Configuring dhcpcd for ... linux Using compiler .. /usr/bin/x86_64-pc-linux-gnu-clang clang version 3.5.0 (tags/RELEASE_350/final) dhcpcd-definitions.conf will be embedded in dhcpcd itself Testing for nl80211 ... yes Testing for getifaddrs ... yes Testing for clock_gettime ... yes Testing for inet_ntoa ... yes Testing for arc4random ... no Testing for arc4random_uniform ... no Testing for closefrom ... no Testing for getline ... yes Testing for strlcpy ... no Testing for dprintf ... yes Testing for TAILQ_FOREACH_SAFE ... no Testing for TAILQ_CONCAT ...yes Testing for posix_spawn ... yes Testing for pollts ... no Testing for ppoll ... yes Testing for LOG_PERROR ... yes Testing for be64enc ... no Testing for MD5Init ... no Testing for sha2.h ... no Testing for SHA256_Init ... no Testing for SHA256Init ... no Checking for libudev ... yes Checking udev_monitor_filter_add_match_subsystem_devtype ... yes Checking udev_device_get_is_initialized ... yes Testing for dlopen ... yes (-ldl) Checking for ntpd ... /usr/sbin/ntpd (50-ntp.conf) Checking for ypbind ... not found Finding hook ntp.conf ... 50-ntp.conf Finding hook yp.conf ... 50-yp.conf SYSCONFDIR = /etc SBINDIR = /sbin LIBDIR = /lib64 LIBEXECDIR = /lib/dhcpcd DBDIR = /var/lib/dhcpcd RUNDIR = /run MANDIR = /usr/share/man HOOKSCRIPTS = 50-ntp.conf 50-yp.conf
(In reply to Michał Górny from comment #8) > It's a custom configure script, so it doesn't spit config.log. But well, > everyone can write a good build system, can't they? :) Unsure if sarcastic? I dislike the weight that autoconf or cmake brings and the fact I had to "re-learn" autoconf each time it upgraded. As someone already noted it works fine outside of portage, but anyone can write a good packaging system yes? I'll note dhcpcd works fine in pkgsrc when swapping compilers around but I suspect that is not the real issue. > As for one of the issues, I already pinged WilliamH and suggested to export > CC. For the other, we'd need to look what's wrong with the check. http://roy.marples.name/projects/dhcpcd/ci/abf5f67e07b1dfab51fe2547d91e7494083ed4d9?sbs=0 That may help as I've moved the "does CC work" test further down the chain as one of the CPPFLAGS or CFLAGS could be stopping it from working. I'll work on adding a config.log or something to the configure as well.

If the OP emerges dhcpcd-9999 then hopefully config.log will shed some light on the matter.
I emerged 9999 and it worked fine. Then I tried to downgrade to 6.4.5 again, and that now worked fine too; gcc is used for the build and all tests pass with no issues. I cannot explain what is happening.

Well, I guess it's fixed then. Though it might be important for people who do actually want to use clang to find out why the test is failing. If I compile the test manually with clang, it works correctly: #include <sys/types.h> #include <ifaddrs.h> int main(void) { struct ifaddrs *ifap; return getifaddrs(&ifap); } running it by hand will pass the test: $ clang getifaddrs.c $ if ./a.out; then echo "yes"; fi yes it only fails when emerging.
dhcpcd-6.4.7 is now in the tree, so this issue should now be fixed.
