Re: RH7.1, PHP4, and ucd-snmp

Thanks Rasmus - problem solved here. Your corrections to ext/snmp/config.m4 worked an should be added to the source (if they have not already). Though your advise to the original poster, did not help him it cured a box of mine where I previously had SNMP functions compiled into a php apache module. Upgrading the ucd-snmp packages, gave ssl support which php did not like too much. system: php-4.0.2.tar.gz RedHat-6.2 with some rebuilt src.rpm's from RedHat-7.1: openssl-perl-0.9.6-3, openssl-0.9.6-3, ucd-snmp-4.2-12, ucd-snmp-utils-4.2-12 openssl-python-0.9.6-3, ucd-snmp-devel-4.2-12, openssl-devel-0.9.6-3 config.nice - used to locate the error: #! /bin/sh # # Created by configure "./configure" \ "--with-openssl" \ "--with-snmp" \ "--enable-ucd-snmp-hack" \ "$@" debug.log - with errors: CONFIGURE: './configure' '--with-openssl' '--with-snmp' '--enable-ucd-snmp-hack' CC: gcc CFLAGS: -g -O2 CPPFLAGS: CXX: CXXFLAGS: INCLUDES: -I$(top_builddir)/Zend -I$(top_srcdir) -I/usr/include/freetype -I/usr/local/src/php-4.0.2/ext/mysql/libmysql -I/usr/include/ucd-snmp LDFLAGS: LIBS: -lsnmp -lttf -lpng -lz -lgd -lresolv -lm -ldl -lcrypt -lnsl -lresolv DLIBS: SAPI: cgi PHP_RPATHS: uname -a: Linux localhost.localdomain 2.2.14-5.0 #1 Tue Mar 7 21:07:39 EST 2000 i686 unknown gcc -o conftest -g -O2 conftest.c -lsnmp -lttf -lpng -lz -lgd -lresolv -lm -ldl -lcrypt -lnsl -lresolv 1>&5 /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `EVP_DigestInit' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `EVP_DigestFinal' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `EVP_md5' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `HMAC' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `EVP_sha1' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `des_cbc_encrypt' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `des_key_sched' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `EVP_DigestUpdate' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `RAND_bytes' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libsnmp.so: undefined reference to `des_ncbc_encrypt' collect2: ld returned 1 exit status BTW: $ /sbin/ldconfig -p| grep crypto libk5crypto.so.2 (libc6) => /usr/kerberos/lib/libk5crypto.so.2 libk5crypto.so (libc6) => /usr/kerberos/lib/libk5crypto.so libcrypto.so.1 (libc6) => /usr/lib/libcrypto.so.1 libcrypto.so (libc6) => /usr/lib/libcrypto.so and $ cc -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs gcc version 2.96 20000731 (Red Hat Linux 7.0) Adding the + lines to ext/snmp/config.m4 file. > if test "$ac_cv_header_default_store_h" = "yes"; then > dnl UCD SNMP 4.1.x > + AC_CHECK_LIB(crypto, CRYPTO_free, SNMP_LIBS=-lcrypto) > + LIBS="$LIBS $SNMP_LIBS" > AC_TRY_RUN([ and running ./buildconf solved the problem, and gave a working php executable.
