[-- Attachment #1 --] I'm developing a threaded package using standard pthread symantics. My gcc compile line includes -pthread to link in libc_r instead of libc, but I gt these warning messages: /usr/lib/libc.so.4: WARNING! setkey(3) not present in the system! /usr/lib/libc.so.4: warning: this program uses gets(), which is unsafe. /usr/lib/libc.so.4: warning: mktemp() possibly used unsafely; consider using mkstemp() /usr/lib/libc.so.4: WARNING! des_setkey(3) not present in the system! /usr/lib/libc.so.4: WARNING! encrypt(3) not present in the system! /usr/lib/libc.so.4: warning: tmpnam() possibly used unsafely; consider using mkstemp() /usr/lib/libc.so.4: warning: this program uses f_prealloc(), which is not recommended. /usr/lib/libc.so.4: WARNING! des_cipher(3) not present in the system! /usr/lib/libc.so.4: warning: tempnam() possibly used unsafely; consider using mkstemp() First, I thought -pthread links libc_r instead of libc. Why is this showing up here? Second, my program doesn't even use setkey, gets, mktemp, des_setkey, encrypt, tmpnam, f_prealloc, des_cipher, nor tempnam. From where are these references coming? The funny thing is, I've developed apps before that use pthreads, and I didn't get these warnings. I don't know what is different. They were much smaller projects, and I no longer have the source code to reference. How do I fix these warnings? I'm running FBSD 4.5-Stable (cvs'd sources mid Februrary). Gcc version is 2.95.3. Language is C. Don't know what other info would be of use, but will be glad to answer questions. Thanks, Kevin -- This message was signed by GnuPG.
