undefined reference to `__ctype_b' (ATTN: Paul Pluzhnikov)
Tristan Miller
I'm trying to rebuild an application from a third-party vendor. Only some
source is provided; the rest of the package consists of compiled libraries
which I presume use an outdated Red Hat glibc-2.0. When I try to build on
my SuSE 9.3 glibc-2.3.4 system, I get many errors of the following form:
/tmp/inquery-3.2/obj/inqr.o(.text+0x8cc): In function
`inqr_write_top_n_docs':
/usr/wag/users1/connell/inquery/linux-build/src/inqr.c:610: undefined
reference to `__ctype_b'
The same error occurs for the symbols __ctype_tolower and __ctype_toupper.
I found a recent Usenet post by Paul Pluzhnikov at
<news:m3slyqn...@somewhere.in.california.localhost> which suggested
recompiling my glibc from the source RPM, except with a patched
locale/lc-ctype.c file as follows:
-compat_symbol (libc, __ctype_b, __ctype_b, GLIBC_2_0);
-compat_symbol (libc, __ctype_tolower, __ctype_tolower, GLIBC_2_0);
-compat_symbol (libc, __ctype_toupper, __ctype_toupper, GLIBC_2_0);
+versioned_symbol (libc, __ctype_b, __ctype_b, GLIBC_2_0);
+versioned_symbol (libc, __ctype_tolower, __ctype_tolower, GLIBC_2_0);
+versioned_symbol (libc, __ctype_toupper, __ctype_toupper, GLIBC_2_0);
I did this. However, upon recompiling, I now get the following errors when
the make gets to lc-ctype.c:

Any idea what's wrong or how to fix it?

The magic incantation has changed.
For libc-2.3.5-10, the new "spell" is this:
