In response to my proposition for organization of headers/libraries
to accomodate both MiNT and TOS in a transparent manner Julian Reschke

I am sorry, but in that case I do not know what do you want. Maybe we
can have some examples, please.
For those who may not know. I spent enough time dabbling in gcc-ST
headers and libraries to know that current headers are unified and
few neccessary differences can be easily accomodated internally
using #ifdef...#endif. My example with <stdio.h> was just that, an
example. Still, I had an impression that Julian, with a support of
Eric, needs/wants some extra, separate header files which will live
in their own subdirectories. That is fine as well if such need
arises. I only indicated that we do not need to burden a compiler
user with a need to explicitely refer to these subtrees. All magic
can be simply hidden in a compiler driver.
As far as library go this is somewhat more complicated. A bulk of TOS
and MiNT libraries is exactly the same. Still there are some
functions with the same names (and which have to have the same names)
which are doing somewhat different things for MiNT and TOS. Keeping
them in the same library and leaving for a linker to sort them out may
be somewhat difficult. :-) On the other hand it does not require much
smarts from a compiler driver to pick up proper sub-libraries and pass
them to 'ld' in a linking phase.
Last but not least. My suggestion to use zmodem for a conversion
between LF and CR/LF line terminators was not entirely serious. I
even added a 'smiley face' for those less observant. If your editor
is unhappy in an absence of CR and will not add these characters for
you then something in this style (adjust to your particular shell)
should work for LF -> CR/LF conversion:
for file in $*
do
cat $file > $TEMP/$file
mv $TEMP/$file $file
done
The above assumes ST, more or less sane 'cat' and "text i/o". Awk or
Perl will work equally well. Going the other way may require some
utility since you need binary file write but entropy promissed to
solve that problem for you.
For those with Unix machines handy here are two conversion scripts
(but replace ^M and ^Z in the second script with their real control
counterparts which would not survive e-mail).
#!/bin/sh
#clean
#shell script for removal of all ^M's and ^Z's from a file or files
#do not use that on binaries
#
for file in $*
do
# echo $file
tr -d '\015\032' < $file >/tmp/$file.$$
mv /tmp/$file.$$ $file
done
exit 0
#!/bin/sh
#mess
#shell script for adding ^M's to all lines in a text file
#do not use that on binaries
#
for file in $*
do
# echo $file
sed 's/$/^M/' $file >/tmp/$file.$$
# uncomment the next line if you really would like to be MS-DOSish
# echo '^Z' >> /tmp/$file.$$
mv /tmp/$file.$$ $file
done
exit 0
Happy conversions
