Building and Installation

The distribution of this package will probably be done as a compressed "tar"-format file available via anonymous FTP from SIPB.MIT.EDU. Retrieve `pub/com_err.tar.Z' and extract the contents. A subdirectory profiled should be created to hold objects compiled for profiling. Running "make all" should then be sufficient to build the library and error-table compiler. The files `libcom_err.a', `libcom_err_p.a', `com_err.h', and `compile_et' should be installed for use; `com_err.3' and `compile_et.1' can also be installed as manual pages.

Potential problems:

• Use of strcasecmp, a routine provided in BSD for case-insensitive string comparisons. If an equivalent routine is available, you can modify CFLAGS in the makefile to define strcasecmp to the name of that routine.
• Compilers that defined __STDC__ without providing the header file <stdarg.h>. One such example is Metaware's High "C" compiler, as provided at Project Athena on the IBM RT/PC workstation; if __HIGHC__ is defined, it is assumed that <stdarg.h> is not available, and therefore <varargs.h> must be used. If the symbol VARARGS is defined (e.g., in the makefile), <varargs.h> will be used.
• If your linker rejects symbols that are simultaneously defined in two library files, edit `Makefile' to remove `perror.c' from the library. This file contains a version of perror(3) which calls com_err instead of calling write directly.

As I do not have access to non-BSD systems, there are probably bugs present that may interfere with building or using this package on other systems. If they are reported to me, they can probably be fixed for the next version.
