slang.so problems

I have had problems relating to slang.so when building boot-floppies. I don't entirely understand what is going on, so I'm posting the facts as I see them, so others can comment.

There are three packages, slang1, slang1-dev, slang1-pic (-pic probably isn't relevant here).

The basic problem is that slang1 provides only libslang1.so.1 and libslang.so.1.4.4, but various things expect libslang.so and so wont run unless sland1-dev is installed. slang1-dev provides libslang.so.

Things I have found that are affected are cfdisk (in util-linux), whiptail, and libnewt0.

As a test I installed the three slang1 packages from the debian archive and did "gcc -o hw hw.c -lslang; ldd hw". I get:

        libslang.so => /usr/lib/libslang.so (0x4002b000)
        libc.so.6 => /lib/libc.so.6 (0x400b0000)
        libm.so.6 => /lib/libm.so.6 (0x401f4000)
        libdl.so.2 => /lib/libdl.so.2 (0x40234000)
        /lib/ld.so.1 => /lib/ld.so.1 (0x40000000)

If I now remove slang1-dev, and try to run hw I get

./hw: error while loading shared libraries: libslang.so: cannot load shared object file: No such file or directory

If I build my own slang1 packages and install them and then remake 'hw', I get

        libslang.so.1 => /lib/libslang.so.1 (0x4002b000)
        libc.so.6 => /lib/libc.so.6 (0x400b0000)
        libm.so.6 => /lib/libm.so.6 (0x401f4000)
        libdl.so.2 => /lib/libdl.so.2 (0x40234000)
        /lib/ld.so.1 => /lib/ld.so.1 (0x40000000)

and 'hw' runs fine with slang1-dev removed, as it should.

cfdisk from the debain archive wont run unless slang1-dev is installed. If I rebuild cfdisk myself, with the debian slang1 packages installed, cfdisk still wants libslang.so. If I rebuild cfdisk with my own build slang1 packages installed, the resulting cfdisk wants libslang.so.1, as it should.

So, it seems something is wrong with the slang1 packages in debian, and that has resulted in bad util-linux, whiptail, and libnewt0 builds.

I don't know what might have gone wrong with the debian builds, because when I build slang1 debs they are fine.

Can someone else try this, and, if appropriate, upload new slang*, util-linux, whiptail, and libnewt0 packages to the archive?

Thanks,
Richard

This still isn't solved. If you install the slang1 and util-linux from the archive, and do not install slang1-dev, then cfdisk will not run:

We are only getting away with this because the slang1_1.4.4.0.1-1_hppa.deb in my install tree is hacked to provide libslang.so.

It doesn't look like there's a bugs.debian.org report about this. Maltranar is perhaps the person who could file the most informed defect report.
