While looking at the "-h" problem (caused by passing -shared to
Sun ld), I noticed serveral glitches.
elsbeth> configure --with-smbwrapper
loading cache ./config.cache
checking for gcc... (cached) gcc
checking whether we are using GNU C... (cached) yes
I don't use gcc, although an old copy does exist
on the machine in /usr/local. The first test is
correct, the second erronious, and the erronious
result end up in my makefile as CC=gcc.
checking for _read... (cached) yes
checking for __read... (cached) no
In Unix, this is a bit doubtfull. The
_ and __ namespaces are reserved for the
implementer's under-the-covers fiddling.
Calling _read instead of read is generally
bad: in a shared library interceptor, one
p = (void *)dlsym((void *)handle, (const char *)"read");
[The Solarii actually use _read for calls to a
read that can't be interecepted...]
checking for _write... (cached) yes
checking for __write... (cached) no
checking for _fork... (cached) yes
checking for __fork... (cached) no
checking for _stat64... (cached) yes
checking for __stat64... (cached) no
checking for _fstat64... (cached) yes
checking for __fstat64... (cached) no
and so on...
Commenting out CC=gcc in the Makefile
produces some other problems: I'll send them next.
