Assuming http://ci.lille.inria.fr/pharo/view/Cog/job/Cog-VM/Architecture=32,OS=linux/... as linked from http://www.pharo-project.org/pharo-download is the official Linux VM used by the whole build process, I am confused about the dependencies of the shipped SSL plugin. On my Ubuntu machine, the following output is of the working plugin: ubuntu@ip-10-48-234-254:~/experimental$ ldd bin/libSqueakSSL.so linux-gate.so.1 => (0xb7702000) libm.so.6 => /lib/i386-linux-gnu/tls/i686/nosegneg/libm.so.6 (0xb76c6000) libdl.so.2 => /lib/i386-linux-gnu/tls/i686/nosegneg/libdl.so.2 (0xb76c1000) libpthread.so.0 => /lib/i386-linux-gnu/tls/i686/nosegneg/libpthread.so.0 (0xb76a6000) libssl.so.0.9.8 => /lib/i386-linux-gnu/libssl.so.0.9.8 (0xb7657000) libc.so.6 => /lib/i386-linux-gnu/tls/i686/nosegneg/libc.so.6 (0xb74ad000) /lib/ld-linux.so.2 (0xb7703000) libcrypto.so.0.9.8 => /lib/i386-linux-gnu/libcrypto.so.0.9.8 (0xb7334000) libz.so.1 => /lib/i386-linux-gnu/libz.so.1 (0xb731e000) While the following output is of the non-working version downloaded from the links above ubuntu@ip-10-48-234-254:~/experimental$ ldd pharocog/libSqueakSSL.so linux-gate.so.1 => (0xb77a7000) libssl.so.6 => not found libc.so.6 => /lib/i386-linux-gnu/tls/i686/nosegneg/libc.so.6 (0xb75ee000) /lib/ld-linux.so.2 (0xb77a8000) What package has to be installed to resolve this dependency ? Against which library was this variant of the SSL plugin built ? I alread have both the following ubuntu@ip-10-48-234-254:~/experimental$ aptitude search "~i" | grep ssl i A libio-socket-ssl-perl - Perl module implementing object oriented i i A libnet-ssleay-perl - Perl module for Secure Sockets Layer (SSL) i libssl0.9.8 - SSL shared libraries i A libssl1.0.0 - SSL shared libraries i openssl - Secure Socket Layer (SSL) binary and relat i python-openssl - Python wrapper around the OpenSSL library i A ssl-cert - simple debconf wrapper for OpenSSL Thx, Sven
