This is strace 3.0, a system call tracer for SunOS 4.x, Linux, System V release 4 and Solaris 2.x. strace is released under a Berkeley-style license; see the file COPYRIGHT for details. The configure script is produced by GNU autoconf and is under the GNU Public License; see the file COPYING for details. Binary distributions of strace which do not include configure are not affected by the GPL. Read the INSTALL file for generic instructions on how to install strace. If configure cannot guess your system configuration, you can specify it on the command line after the other options like this: ./configure --prefix=/usr i486-linux The following configurations are supposed to work: sparc-sun-sunos4.1 i486-linux i486-ncr-sysv4 sparc-sun-solaris2 A single sunos4.1 binary should work on all the sun4, sun4c and sun4m kernel architectures. Other i486-*-sysv4 systems may work with little or no tweaking. The solaris2 configuration has only been tested with GCC. Please send bug reports and enhancements to Rick Sladkey .
