building slang2 with UTF-8 support on MacOS X

[Christian Ebert]

Hello,

Has anybody successfully compiled slang2 with UTF-8 support on
MacOS X? I recently switch to UTF locale and want to build the
slrn preview against slang2.

Here, on MacOS 10.3.9 I seem to be able to build the dynamic
libraries in the src dir, but I can't get through to the utf
module. make elf in the top dir stalls always at slsh with:


$ tail -n20 slang_make.log
libslang.2.0.7.dylib created in /Users/chris/src/slang/src/elfobjs.
The link libslang.dylib to libslang.2.0.7.dylib was also created.

cd slsh; make all
cp ../src/config.h .
gcc -c -I/sw/include -I/Users/chris/src/slang/src -DSLSH_CONF_DIR='"/usr/local/etc"' -DSLSH_PATH='"/usr/local/share/slsh"' -DSLSH_CONF_DIR_ENV='"SLSH_CONF_DIR"' -DSLSH_LIB_DIR_ENV='"SLSH_LIB_DIR"' -DSLSH_PATH_ENV='"SLSH_PATH"' slsh.c
gcc -c -I/sw/include -I/Users/chris/src/slang/src -DSLSH_CONF_DIR='"/usr/local/etc"' -DSLSH_PATH='"/usr/local/share/slsh"' -DSLSH_CONF_DIR_ENV='"SLSH_CONF_DIR"' -DSLSH_LIB_DIR_ENV='"SLSH_LIB_DIR"' -DSLSH_PATH_ENV='"SLSH_PATH"' -DUSE_GNU_READLINE=0 readline.c
readline.c: In function `open_readline':
readline.c:197: warning: assignment makes pointer from integer without a cast
readline.c: In function `read_input_line':
readline.c:284: warning: assignment makes pointer from integer without a cast
readline.c: In function `get_input_line':
readline.c:363: error: `SL_RunTime_Error' undeclared (first use in this function)
readline.c:363: error: (Each undeclared identifier is reported only once

readline.c: In function `readline_intrinsic_internal':
readline.c:555: warning: assignment makes pointer from integer without a cast
make[1]: *** [readline.o] Error 1
make: *** [elf] Error 2

I get more or less the same error with --with-readline=gnu.

It is the same with slang-2.0.6 or slang svn-r34.

I can build slrn with the dylibs but appararently they are not
recognized, or only halfway: with latest cvs HEAD of slrn the
umlauts (ä, ö etc.) are displayed correctly, but it fails on "ß"
(sz lig) already. And slrn -V says it has slang-1.4?

Any help or pointers are appreciated.

Does it help if you remove -I/sw/include? Does /sw/include contain an
older version of slang.h?

Thanks,

Oops, I passed the wrong CFLAGS. My head was already spinning
from all the different versions and combinations of different
versions I was trying.

Ok. The svn-r34 libraries without any modules installed, and
writing this with cvs HEAD of slrn. And it works! slrn-pl1
however does not display 8bit chars correctly, neither does your
patch for 9.8.1 that I found on the web. -- With cvs HEAD I have
to do
LDFLAGS="-liconv" ./configure ..
though which is not needed for the tarball preview.

.. but slrn in the current state is unforgiving: it breaks on
headers with quotes like charset="iso-8859-1". If at least it
would not just give an error, I could just replace the article
with a little "display-filter" that I wrote that would call iconv
directly in case there's a header like that. But this way I only
get the error:

cannot convert from iso-8859-1"

mark the trailing quote. So I learn how many posts actually have
a broken charset header, but I can't read them. Duh. I guess I'll
have to wait until there's a more tolerant version. Pity. --
Unless you happen to have an idea where I could tweak something.

Thanks anyway for input.

Hi John,

Does it help if you remove -I/sw/include? Does /sw/include contain an
older version of slang.h?

FYI, I removed slang-1.4.9 completely and kept -I/sw/include.
This time the modules compiled too, except for socket. I found
only one socket.h in /usr/include/sys, but issuing
-I/usr/include/sys as well wasn't an improvement.

Unfortunately (for me) this changed nothing on the slrn front:
Articles quoted charset headers and format-flowed only give an
error -- even though UTF-8 and charset declarations without
quotes work fine.

Anyway, I have now a brand new slang2 and slrn compiled against
it ... but still no UTF.

$ slrn --version

BTW, sorry for the double post, don't know whether this was due
to slrn or my confusion, probably the latter.

I will look into what needs to be done to get the socket module
running on MacOS X.

This is an slrn problem and should be dealt with by the slrn
maintainers. I believe Thomas Schultz is still maintaining it.
See <http://www.slrn.org/> for the appropriate links.

Good luck,

The latest version of the socket-module in the SVN repository should
work on MacOS X.

It does indeed.

Thank you very much for your help.
