When building samba-4.1.17, the configure step fails because `heim_cmp` could not be found with the following output in the config log: [2/2] Linking default/testprog /usr/lib64/libheimbase.so: undefined reference to `pthread_getspecific' /usr/lib64/libheimbase.so: undefined reference to `pthread_key_create' /usr/lib64/libheimbase.so: undefined reference to `pthread_setspecific' collect2: error: ld returned 1 exit status ['x86_64-pc-linux-gnu-gcc', 'default/test_1.o', '-o', '/var/tmp/paludis/net-fs-samba-4.1.17/work/samba-4.1.17/bin/.conf_check_0/testbuild/default/testprog', '-O2', '-pipe', '-march=native', '-g', '-Wl,-O1,--hash-style=gnu,--sort-common', '-Wl,--as-needed', '-Wl,-O1,--hash-style=gnu,--sort-common', '-Wl,--as-needed', '-fstack-protector', '-Wl,-no-undefined', '-L/usr/local/lib', '-L/usr/lib64', '-Wl,-Bdynamic', '-lheimbase'] `ldd /usr/lib64/libheimbase.so` for app-crypt/heimdal-1.5.3-r2[X,berkdb,caps,ipv6,pkinit,threads] gives: linux-vdso.so.1 (0x00007fff581c4000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00007f2a1c7b2000) libc.so.6 => /lib64/libc.so.6 (0x00007f2a1c1e9000) /lib64/ld-linux-x86-64.so.2 (0x00007f2a1cc27000) Relevant flags and packages: CHOST="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -march=native -g" CXXFLAGS="${CFLAGS}" LDFLAGS="-Wl,-O1,--hash-style=gnu,--sort-common -Wl,--as-needed" sys-devel/gcc 4.9.2 sys-libs/glibc 2.20-r2 When removing '-Wl,--as-needed' from LDFLAGS, building heimdal itself fails in the linking phase for libheimbase.so: /bin/sh ../../libtool --tag=CC --mode=link x86_64-pc-linux-gnu-gcc -m32 -Wall -Wmissing-prototypes -Wpointer-arith -Wbad-function- cast -Wmissing-declarations -Wnested-externs -O2 -pipe -march=native -g -fno-strict-aliasing -Wl,-O1,--hash-style=gnu,--sort-common -o tc tc.o libheim-ipcc.la ../../lib/vers/libvers.la ../../lib/roken/libroken.la -lcrypt -lresolv libtool: link: x86_64-pc-linux-gnu-gcc -m32 -Wall -Wmissing-prototypes -Wpointer-arith -Wbad-function-cast -Wmissing-declarations -Wne sted-externs -O2 -pipe -march=native -g -fno-strict-aliasing -Wl,-O1 -Wl,--hash-style=gnu -Wl,--sort-common -o .libs/tc tc.o ./.libs/ libheim-ipcc.a /var/tmp/paludis/app-crypt-heimdal-1.5.3-r2/work/heimdal-1.5.3-abi_x86_32.x86/base/.libs/libheimbase.so /var/tmp/paludi s/app-crypt-heimdal-1.5.3-r2/work/heimdal-1.5.3-abi_x86_32.x86/lib/roken/.libs/libroken.so ../../lib/vers/.libs/libvers.a ../../lib/ro ken/.libs/libroken.so -lcrypt -lresolv /var/tmp/paludis/app-crypt-heimdal-1.5.3-r2/work/heimdal-1.5.3-abi_x86_32.x86/base/.libs/libheimbase.so: undefined reference to `pthread_getspecific' /var/tmp/paludis/app-crypt-heimdal-1.5.3-r2/work/heimdal-1.5.3-abi_x86_32.x86/base/.libs/libheimbase.so: undefined reference to `pthread_key_create' /var/tmp/paludis/app-crypt-heimdal-1.5.3-r2/work/heimdal-1.5.3-abi_x86_32.x86/base/.libs/libheimbase.so: undefined reference to `pthread_setspecific' When adding '-pthread' to CFLAGS for heimdal, `ldd ...` shows correctly: linux-vdso.so.1 (0x00007fff623f7000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00007fea11d65000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fea11b49000) libc.so.6 => /lib64/libc.so.6 (0x00007fea1179c000) /lib64/ld-linux-x86-64.so.2 (0x00007fea121da000) and building samba succeeds.

(In reply to Alex Barker from comment #1) > CFLAGS=-pthread does not work for me. CFLAGS && CXXFLAGS works.
