First cvs version. +# 2004-12-13: Add traps to cleanup temp files, from Amarendra Godbole. +# +# "OpenSSL headers do not match your library" are usually caused by +# OpenSSH's configure picking up an older version of OpenSSL headers +# or libraries. You can use the following # procedure to help identify +# the cause. +# +# The output of configure will tell you the versions of the OpenSSL +# headers and libraries that were picked up, for example: +# +# checking OpenSSL header version... 90604f (OpenSSL 0.9.6d 9 May 2002) +# checking OpenSSL library version... 90602f (OpenSSL 0.9.6b [engine] 9 Jul 2001) +# checking whether OpenSSL's headers match the library... no +# configure: error: Your OpenSSL headers do not match your library +# +# Now run findssl.sh. This should identify the headers and libraries +# present and their versions. You should be able to identify the +# libraries and headers used and adjust your CFLAGS or remove incorrect +# versions. The output will show OpenSSL's internal version identifier +# and should look something like: + +# $ ./findssl.sh +# Searching for OpenSSL header files. +# 0x0090604fL /usr/include/openssl/opensslv.h +# 0x0090604fL /usr/local/ssl/include/openssl/opensslv.h +# +# Searching for OpenSSL shared library files. +# 0x0090602fL /lib/libcrypto.so.0.9.6b +# 0x0090602fL /lib/libcrypto.so.2 +# 0x0090581fL /usr/lib/libcrypto.so.0 +# 0x0090602fL /usr/lib/libcrypto.so +# 0x0090581fL /usr/lib/libcrypto.so.0.9.5a +# 0x0090600fL /usr/lib/libcrypto.so.0.9.6 +# 0x0090600fL /usr/lib/libcrypto.so.1 +# +# Searching for OpenSSL static library files. +# 0x0090602fL /usr/lib/libcrypto.a +# 0x0090604fL /usr/local/ssl/lib/libcrypto.a +# +# In this example, I gave configure no extra flags, so it's picking up +# the OpenSSL header from /usr/include/openssl (90604f) and the library +# from /usr/lib/ (90602f). + +# +# Adjust these to suit your compiler. +# You may also need to set the *LIB*PATH environment variables if +# DEFAULT_LIBPATH is not correct for your system. +# +CC=gcc +STATIC=-static + +# +# Cleanup on interrupt +# +trap 'rm -f conftest.c' INT HUP TERM + +# +# Set up conftest C source +# +rm -f findssl.log +cat >conftest.c <<EOD +#include <stdio.h> +int main(){printf("0x%08xL\n", SSLeay());} +EOD + +# +# Set default library paths if not already set +# +DEFAULT_LIBPATH=/usr/lib:/usr/local/lib +LIBPATH=${LIBPATH:=$DEFAULT_LIBPATH} +LD_LIBRARY_PATH=${LD_LIBRARY_PATH:=$DEFAULT_LIBPATH} +LIBRARY_PATH=${LIBRARY_PATH:=$DEFAULT_LIBPATH} +export LIBPATH LD_LIBRARY_PATH LIBRARY_PATH + +# not all platforms have a 'which' command +if which ls >/dev/null 2>/dev/null; then + : which is defined +else + which () { + saveIFS="$IFS" + IFS=: + for p in $PATH; do + if test -x "$p/$1" -a -f "$p/$1"; then + IFS="$saveIFS" + echo "$p/$1" + return 0 + fi + done + IFS="$saveIFS" + return 1 + } +fi + +# +# Search for OpenSSL headers and print versions +# +echo Searching for OpenSSL header files. +if [ -x "`which locate`" ] +then + headers=`locate opensslv.h` +else + headers=`find / -name opensslv.h -print 2>/dev/null` +fi + +for header in $headers +do + ver=`awk '/OPENSSL_VERSION_NUMBER/{printf \$3}' $header` + echo "$ver $header" +done +echo + +# +# Search for shared libraries. +# Relies on shared libraries looking like "libcrypto.s*" +# +echo Searching for OpenSSL shared library files. +if [ -x "`which locate`" ] +then + libraries=`locate libcrypto.s` +else + libraries=`find / -name 'libcrypto.s*' -print 2>/dev/null` +fi + +for lib in $libraries +do + (echo "Trying libcrypto $lib" >>findssl.log + dir=`dirname $lib` + LIBPATH="$dir:$LIBPATH" + LD_LIBRARY_PATH="$dir:$LIBPATH" + LIBRARY_PATH="$dir:$LIBPATH" + export LIBPATH LD_LIBRARY_PATH LIBRARY_PATH + ${CC} -o conftest conftest.c $lib 2>>findssl.log + if [ -x ./conftest ] + then + ver=`./conftest 2>/dev/null` + rm -f ./conftest + echo "$ver $lib" + fi) +done +echo + +# +# Search for static OpenSSL libraries and print versions +# +echo Searching for OpenSSL static library files. +if [ -x "`which locate`" ] +then + libraries=`locate libcrypto.a` +else + libraries=`find / -name libcrypto.a -print 2>/dev/null` +fi + +for lib in $libraries +do + libdir=`dirname $lib` + echo "Trying libcrypto $lib" >>findssl.log + ${CC} ${STATIC} -o conftest conftest.c -L${libdir} -lcrypto 2>>findssl.log + if [ -x ./conftest ] + then + ver=`./conftest 2>/dev/null` + rm -f ./conftest + echo "$ver $lib" + fi +done + +# +# Clean up +# +rm -f conftest.c |
