I'm trying to build a tiny test program using an alternate toolchain
built purely from source (LFS ch. 5 method), but collect2 says that ld
can't find a lib. that _does_ exist under /usr/lib, but /usr/lib is not
even attempted as part of the search, even though /usr/lib _is_ part of
the library search path dumped by "gcc -print-search-dirs".
Bizarre...what am I misunderstanding?
Here are the particulars:
The program I'm building:
#include <stdio.h>
int main() { printf("Ok\n"); return(0); }
The build command line:
/tools/bin/gcc -o
try -O2 -fno-strict-aliasing -pipe -Wdeclaration-after-statement -I/usr/local/include -L/usr/local/lib
try.c -lnsl -lgdbm -ldb -ldl -lm -lcrypt -lutil -lc -Wl,--verbose
The failure:
/data/devo/builds/i686-pc-linux-uclibc/orsus-2/rootfs/tools/bin/../lib/gcc/i686-pc-linux-uclibc/4.2.2/../../../../i686-pc-linux-uclibc/bin/ld:
cannot find -lgdbm
collect2: ld returned 1 exit status
The pertinent parts of the -Wl,--verbose output from the build attempt:
GNU ld (GNU Binutils) 2.18

Note the /usr/lib on the last line!
Just for reference,
ls -al /usr/lib/libgdbm*
-rw-r--r-- 1 root root 123184 2009-02-11 16:05 /usr/lib/libgdbm.a
-rw-r--r-- 1 root root 83410 2009-02-11 16:05 /usr/lib/libgdbm_compat.a
So WHY is /usr/lib NOT being searched by ld? Isn't collect2 supposed to
pass on the same library paths as dumped by gcc -print-search-dirs to
ld? Any ideas?

Also, note that I am doing a native build on a i686-pc-linux-uclibc
system that works fine in all other regards...except that this is an
alternate toolchain's gcc that I'm using...but its still
i686-pc-linux-uclibc.
Any ideas?
Thanks,
John
