Improve situation with clang for 1989/westley
The alt code has been changed so that in addition to the main feature working it will also generate ver0 and ver1 correctly; ver2 and ver3 cannot be compiled still. This is not perfect but it is progress. I will look at this further later most likely. Added compile.alt.sh to compile the alt code and generate the alt code generated code. It generates it in the file name form alt.ver[0-3].c and the code will be compiled as such. Added try.sh to demonstrate the main (original) program. This is because there are a lot of commands to try. Added try.alt.sh to demonstrate the alt program (not trying the ver2 and ver3, naturally). The rationale is the same as for try.sh. The Makefile has been updated for these changes. Updated .gitignore as a number of new files will be created when running compile.alt.sh. The bugs.md has been updated as there has been some progress made. The hint was removed at this time as it's not applicable now; the problem of main() args not being allowed is no longer true. However the status line has not been updated because the root of the problem is this. There are currently no hints because I do not have any yet. The thanks file has also been updated for the new scripts as well as the situation being changed.

This entry is a big problem for clang due to the way it is designed. Earlier a
|
||||
change was made to let it compile with clang but although it appeared to work
|
||||
with gcc, all generated versions (see the README.md for details), this was
|
||||
either a mistake or it no longer does.
|
||||
|
||||
Thus the original was copied and this does not work at all in clang. It is very
|
||||
easy to get the first one or two to work with clang but the others result in
|
||||
compilation failures even besides clang.
|
||||
This entry is a big problem for clang due to the way it is designed. An alt
|
||||
code, added by Cody, was made that lets the program work and some of the
|
||||
generated files work but as `ver2` and `ver3` cannot be compiled even with gcc
|
||||
(syntax errors) this is in the alt version.

Cody gives these tips on the problem: `main()`'s second, third and fourth args

Cody was able to get `main()` to be correct BUT a feature is that it uses ROT13

[README.md](1989/westley/README.md) for details).

Since that function does not have the correct types when converted to main() it

Cody got some of the versions (the original and `ver0` and `ver1`) to work with some
|
||||
versions of `clang`. Unfortunately there are some defects in `clang` that break
|
||||
this entry either in full or in part. Also, some of the code generated by it
|
||||
cannot be compiled by gcc either. Thus these changes are in the alt code.
|
||||
Nevertheless the main features of the program does work in the alt version, it
|
||||
just cannot generate every C file correctly.
|
||||
this entry either in full or in part. In particular the first arg to `main()`
|
||||
has to be an int and the rest have to be a `char **` but some versions do not
|
||||
allow four args. So to get past this another function was added, `pain()`, which
|
||||
takes the place of `main()` and which `main()` calls.
|
||||
|
||||
Cody provided the compile.sh script to generate the files and then try and
|
||||
compile them (which ones succeed depend on whether or not clang is the
|
||||
compiler). The script allows one to change the path of the compiler if they have
|
||||
another one. See the README.md for details.
|
||||
This was added as alt code because some of the code generated cannot be compiled
|
||||
by gcc either. To make use of this several scripts were added by Cody.
|
||||
|
||||
As there are some important notes on this in the README.md file we have left the
|
||||
details in that file and further details are in the [bugs.md](bugs.md) file.
|
||||
The [compile.sh](1989/westley/compile.sh) script that removes the generated
|
||||
code, rebuilds the program and regenerates the other code and then compiles it
|
||||
will work for compilers like gcc and one can then use the
|
||||
[try.sh](1989/westley/try.sh) script to see example input and output.
|
||||
|
||||
The [compile.alt.sh](1989/westley/compile.alt.sh) script does the same but for
|
||||
the alt code, which as noted above, can only compile the first two generated
|
||||
versions, at least at this time. The [try.alt.sh](1989/westley/try.alt.sh)
|
||||
script is like the [try.sh](1989/westley/try.sh) script but it uses the alt code
|
||||
and alt generated versions instead.
|
||||
|
||||
Both scripts allow one to specify the compiler which is probably more useful for
|
||||
`compile.sh`.
