The output will show OpenSSL's internal version identifier 37180740Sdes# and should look something like: 38180740Sdes 39180740Sdes# $ ./findssl.sh 40180740Sdes# Searching for OpenSSL header files. 41180740Sdes# 0x0090604fL /usr/include/openssl/opensslv.h 42180740Sdes# 0x0090604fL /usr/local/ssl/include/openssl/opensslv.h 43180740Sdes# 44180740Sdes# Searching for OpenSSL shared library files. 45180740Sdes# 0x0090602fL /lib/libcrypto.so.0.9.6b 46180740Sdes# 0x0090602fL /lib/libcrypto.so.2 47180740Sdes# 0x0090581fL /usr/lib/libcrypto.so.0 48180740Sdes# 0x0090602fL /usr/lib/libcrypto.so 49180740Sdes# 0x0090581fL /usr/lib/libcrypto.so.0.9.5a 50180740Sdes# 0x0090600fL /usr/lib/libcrypto.so.0.9.6 51180740Sdes# 0x0090600fL /usr/lib/libcrypto.so.1 52180740Sdes# 53180740Sdes# Searching for OpenSSL static library files. 54180740Sdes# 0x0090602fL /usr/lib/libcrypto.a 55180740Sdes# 0x0090604fL /usr/local/ssl/lib/libcrypto.a 56180740Sdes# 57180740Sdes# In this example, I gave configure no extra flags, so it's picking up 58180740Sdes# the OpenSSL header from /usr/include/openssl (90604f) and the library 59180740Sdes# from /usr/lib/ (90602f). 60180740Sdes 61180740Sdes# 62180740Sdes# Adjust these to suit your compiler. 63180740Sdes# You may also need to set the *LIB*PATH environment variables if 64180740Sdes# DEFAULT_LIBPATH is not correct for your system. 65180740Sdes# 66180740SdesCC=gcc 67180740SdesSTATIC=-static 68180740Sdes 69180740Sdes# 70180740Sdes# Cleanup on interrupt 71180740Sdes# 72180740Sdestrap 'rm -f conftest.c' INT HUP TERM 73180740Sdes 74180740Sdes# 75180740Sdes# Set up conftest C source 76180740Sdes# 77180740Sdesrm -f findssl.log 78180740Sdescat >conftest.c <<EOD 79180740Sdes#include <stdio.h> 80180740Sdesint main(){printf("0x%08xL\n", SSLeay());} 81180740SdesEOD 82180740Sdes 83180740Sdes# 84180740Sdes# Set default library paths if not already set 85180740Sdes# 86180740SdesDEFAULT_LIBPATH=/usr/lib:/usr/local/lib 87180740SdesLIBPATH=${LIBPATH:=$DEFAULT_LIBPATH} 88180740SdesLD_LIBRARY_PATH=${LD_LIBRARY_PATH:=$DEFAULT_LIBPATH} 89180740SdesLIBRARY_PATH=${LIBRARY_PATH:=$DEFAULT_LIBPATH} 90180740Sdesexport LIBPATH LD_LIBRARY_PATH LIBRARY_PATH 91180740Sdes 92180740Sdes# not all platforms have a 'which' command 93180740Sdesif which ls >/dev/null 2>/dev/null;
