This is an ugly race, which happens because of incorrectly written target dependencies in Makefile. gcc ... -o rwhoisd ... -L../tools/tcpd_wrapper -lwrap ... starts in the same moment as ar rv libwrap.a ... ar (pid 11893) creates the file and writes the magic: 11893 11:49:25.428586 openat(AT_FDCWD, "libwrap.a", O_RDWR|O_CREAT|O_TRUNC, 0666) = 3 11893 11:49:25.429026 write(3, "!<arch>\n", 8) = 8 11893 11:49:25.429073 close(3) = 0 and it starts collecting data from .o files. Meantime, gcc (pid 11894) needs -lwrap, it opens the archive and reads all data, which is only the magic in the moment 11894 11:49:25.527497 faccessat2(AT_FDCWD, "../tools/tcpd_wrapper/libwrap.a", F_OK, AT_EACCESS) = 0 11894 11:49:25.527995 openat(AT_FDCWD, "../tools/tcpd_wrapper/libwrap.a", O_RDONLY) = 7 11894 11:49:25.528122 read(7, "!<arch>\n", 4096) = 8 11894 11:49:25.528156 read(7, "", 4096) = 0 gcc keeps computing but ar finally writes libwrap.a data 11893 11:49:25.543624 openat(AT_FDCWD, "libwrap.a", O_WRONLY|O_TRUNC) = 3 11893 11:49:25.543715 write(3, "!<arch>\n/ 17308937"..., 8192) = 8192 11893 ... 11893 11:49:25.544333 write(3, "\0\0\0\0\0\0\4\0\0\0 \0\0\0\5\0\0\0GNU\0\2\0\1\300\4\0\0\0\0\0"..., 3418) = 3418 11893 11:49:25.544433 close(3) = 0 gcc keeps computing, it never rereads the libwrap.a and later on emits the error as it cannot locate hosts_allow_table, hosts_deny_table and hosts_ctl, which would normally be part of libwrap.a. 11894 ... 11894 11:49:28.157804 write(2, ": undefined reference to `", 26) = 26 11894 11:49:28.157861 write(2, "hosts_allow_table", 17) = 17 11894 11:49:28.157924 write(2, "'\n", 2) = 2 11894 ... 11894 11:49:28.158575 write(2, "hosts_deny_table", 16) = 16 11894 ... 11894 11:49:28.159272 write(2, "hosts_ctl", 9) = 9 11894 ...

This also resolves the bug 740790, where exported STRINGS variable was polluting CFLAGS, similarly to bug 728348. The original patches are bundled to an archive, which additionally contains: - a fix with corrected signal handlers declarations, bug 924504. - corrected dependencies in main Makefile, bug 927273 - obosolete glibc check removal from configure.ac, bug 715310 - replacement of remaings direct ar calls Closes: https://bugs.gentoo.org/715310 Closes: https://bugs.gentoo.org/740790 Closes: https://bugs.gentoo.org/924504 Closes: https://bugs.gentoo.org/927273 Signed-off-by: Petr Vaněk <arkamar@gentoo.org> net-misc/rwhoisd/Manifest | 1 + net-misc/rwhoisd/rwhoisd-1.5.9.6_p1.ebuild | 61 ++++++++++++++++++++++++++++++ 2 files changed, 62 insertions(+)
