tcl.m4 @ 158

Last change on this file since 158 was 158, checked in by mmc, 19 years ago

Fixed installation so that this "gui" part can be installed with standard autoconf techniques: configure, make all, make install The "gui" library is loaded via "package require RapptureGUI"

Added C code for Rappture::rlimit, to support limits on CPU time and file sizes. Default limits are 15 mins of CPU and 1MB for each file. These can be overridden in tool.xml by using <tool><limits><cputime> and <tool><limits><filesize>.

Added C code for Rappture::rusage, so we can collect resource usage for all child processes. Each Simulation now reports a line of usage to stderr as follows:

MiddlewareTime?: job=# event=simulation start=xxx cputime=xxx ...

Fixed Rappture::exec so that it reports proper error messages when rlimits are execeeded.

484	# files into an executable application binary such

489	# the variable LIB_RUNTIME_DIR in the Makefile.

491	# differs depending on whether or not Tcl is being
492	# compiled as a shared library.

518	# Examples: ${VERSION}.so.1.1 on NetBSD, since it needs
519	# to have a version after the .so, and ${VERSION}.a
520	# on AIX, since the Tcl shared library needs to have
521	# a .a extension whereas shared objects for loadable
522	# extensions have a .so extension. Defaults to
