I have application written in C and I have added some message digest functions using openssl and libcrypto. I have linked the library in the Eclipse project via "-lcrypto" and "#include <openssl/evp.h>" in the C file. The application builds fine. However when I deploy and start the application on the cRIO, I am getting the following error at launch: "error while loading shared libraries: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory" I see that my cRIO has libcrypto.so.1.0.2 located in /usr/bin/ I assume I have some version issue. I would have thought 1.0.2 would be enough, does my application specifically call 1.0.0 without me explicitly calling it? admin@NI-cRIO-9030-01C59BCD:/usr/lib/x86_64-linux-gnu/nisysapi# opkg info opensslPackage: opensslVersion: 1.0.2k-r0.40Depends: libc6 (>= 2.24), libcrypto1.0.2 (>= 1.0.2k), libssl1.0.2 (>= 1.0.2k), openssl-confStatus: install ok installedArchitecture: core2-64Installed-Size: 567978Installed-Time: 1537439537 Ok, so it looks like my includes in Eclipse points to C:\build\17.0\lib\, which has libcrypto.so.1.0.0. My cRIO feed is from 18.5, libcrypto.so.1.0.0 is not in //lib. I did find it here /usr/lib/libcrypto.so.1.0.2 Is this a linking/path issue? Edit: I tried creating a symbolic link and now I get this... admin@NI-cRIO-9030-01C59BCD:/usr/lib# ln -s /usr/lib/libcrypto.so.1.0.2 /lib/libcrypto.so.1.0.0admin@NI-cRIO-9030-01C59BCD:/usr/lib# /usr/local/bin/app/usr/local/bin/app: /lib/libcrypto.so.1.0.0: version `OPENSSL_1.0.0' not found (required by /usr/local/bin/app) Which looks like I need to either install openssl1.0.0 on the cRIO or somehow load openssl1.0.2 on my PC and include in the project build? Edit: I downgraded to 2017 drivers and now I have this: admin@NI-cRIO-9030-01C59BCD:/usr/lib# find / -name libcrypto.so*/usr/lib/libcrypto.so.1.0.0admin@NI-cRIO-9030-01C59BCD:/usr/lib# opkg info opensslPackage: opensslVersion: 1.0.2h-r0.121Depends: libssl1.0.0 (>= 1.0.2h), libc6 (>= 2.23), libcrypto1.0.0 (>= 1.0.2h)Status: install ok installedSection: libs/networkArchitecture: core2-64Maintainer: NI Linux Real-Time Maintainers <nilrt@ni.com>MD5Sum: 2ad8c9cc88bee78ee182e1f89a0a5a02Size: 233870Filename: openssl_1.0.2h-r0.121_core2-64.ipkSource: http://www.openssl.org/source/openssl-1.0.2h.tar.gz file://find.pl;subdir=openssl-1.0.2h/util/ file://run-ptest file://configure-targets.patch file://shared-libs.patch file://oe-ldflags.patch file://engines-install-in-libdir-ssl.patch file://debian1.0.2/block_diginotar.patch file://debian1.0.2/block_digicert_malaysia.patch file://debian/ca.patch file://debian/c_rehash-compat.patch file://debian/debian-targets.patch file://debian/man-dir.patch file://debian/man-section.patch file://debian/no-rpath.patch file://debian/no-symbolic.patch file://debian1.0.2/version-script.patch file://openssl_fix_for_x32.patch file://fix-cipher-des-ede3-cfb1.patch file://openssl-avoid-NULL-pointer-dereference-in-EVP_DigestInit_ex.patch file://openssl-fix-des.pod-error.patch file://Makefiles-ptest.patch file://ptest-deps.patch file://openssl-1.0.2a-x32-asm.patch file://ptest_makefile_deps.patch file://configure-musl-target.patch file://parallel.patch file://CVE-2016-2178.patch file://CVE-2016-2179.patch file://CVE-2016-2180.patch file://CVE-2016-2181_p1.patch file://CVE-2016-2181_p2.patch file://CVE-2016-2181_p3.patch file://CVE-2016-2182.patch file://CVE-2016-6302.patch file://CVE-2016-6303.patch file://CVE-2016-6304.patch file://CVE-2016-6306.patch file://0001-crypto-rand-Fix-VxWorks-platform-detection-in-randfi.patch file://0002-crypto-ts-Implement-def_time_cb-on-VxWorks.patch file://0003-ssl-Implement-get_current_time-on-VxWorks.patch file://0004-crypto-bio-Implement-get_current_time-on-VxWorks.patch file://0005-crypto-Implement-OpenSSLDie-as-abort-on-Phar-Lap-ETS.patch file://0006-crypto-Remove-unsupported-headers-in-cryptlib.c-on-P.patch file://0007-crypto-rand-Disable-unsupported-readscreen-on-Phar-L.patch file://0008-crypto-rand-Don-t-include-unsupported-Windows-header.patch file://0009-rand_win.c-Stub-RAND_poll-on-Phar-Lap-ETS.patch file://0010-crypto-des-Disable-WIN_CONSOLE_BUG-hack-on-Phar-Lap-.patch file://0011-crypto-ui-Disable-WIN_CONSOLE_BUG-hack-on-Phar-Lap-E.patch file://0012-crypto-bio-Disable-xopenlog-xcloselog-on-Phar-Lap-ET.patch file://0013-crypto-Use-i686-instead-of-i486-in-MASM-script.patch file://0014-perlasm-x86masm.pl-make-it-work.patchDescription: Secure Socket Layer Secure Socket Layer (SSL) binary and relatedcryptographic tools.Installed-Size: 553336Installed-Time: 1489192102admin@NI-cRIO-9030-01C59BCD:/usr/lib# /usr/local/bin/eclipse_backend/usr/local/bin/eclipse_backend: /usr/lib/libcrypto.so.1.0.0: version `OPENSSL_1.0.0' not found (required by /usr/local/bin/eclipse_backend) Seems like I am closer with now having "libcrypto.so.1.0.0" but something still wants OpenSSL 1.0.0. Looks like I have some mismatch. I am seeing that NI has moved and Linux RT developement from Eclipse (<2017) to Visual Studio. IF there is some package issue in NI's feeds for OpenSSL that is causing this issue, do I need to move to VS?
