[Q12] ``The `gencat' utility cannot process the input which are
successfully used on my Linux libc based system. Why?''
[A12] {UD} Unlike the author of the `gencat' program which is distributed
with Linux libc I have read the underlying standards before writing the
code. It is completely compatible with the specification given in
X/Open Portability Guide.
To ease the transition from the Linux version some of the non-standard
features are also present in the `gencat' program of GNU libc. This
mainly includes the use of symbols for the message number and the automatic
generation of header files which contain the needed #defines to map the
symbols to integers.
Here is a simple SED script to convert at least some Linux specific
catalog files to the XPG4 form:
