Please note that version 1.2.2 is somewhat old. Version 1.2.3 was released recently and fixes several known bugs, but unfortunately it also introduced a build bug for Solaris, at least when using the Sun compiler. The build bug is fixed already and version 1.2.4 will be released very soon but if you need to proceed before it becomes available I would recommend either downloading the source code from our git repository or using a daily snapshot: http://libssh2.org/snapshots/libssh2-1.2.4-20100213.tar.gz > I successfully ran the first command, 'configure CC=/usr/sfw/bin/gcc', > however, got errors in the second command, 'gmake' as follows: > > gmake[2]: Entering directory > `/export/home/achen/perl/SSH2_dependency/libssh2-1.2.2/example/simple' > /bin/bash ../../libtool --tag=CC --mode=link /usr/sfw/bin/gcc -g -O2 -o > ssh2 ssh2.o ../../src/libssh2.la -lnsl -lsocket > libtool: link: /usr/sfw/bin/gcc -g -O2 -o .libs/ssh2 ssh2.o > ../../src/.libs/libssh2.so -lssl -lcrypto -lz -lnsl -lsocket -R/usr/local/lib > Undefined first referenced > symbol in file > EVP_aes_192_cbc ../../src/.libs/libssh2.so > EVP_aes_256_cbc ../../src/.libs/libssh2.so > > Couldn't figure out where to find EVP_aes_192_cbc, EVP_aes_256_cbc > definition. Any suggestion? These are names of encryption algorithms in OpenSSL. The errors mean that your installed version of OpenSSL does not support AES with 192 or 256 bit keys. Would you like to use these key lengths? If so, you must install a version of OpenSSL which supports them. If not, you can either remove the encryption methods from the libssh2 source file src/crypt.c: (line number in brackets) libssh2_crypt_method_aes192_ctr (131) libssh2_crypt_method_aes256_ctr (143) libssh2_crypt_method_aes192_cbc (169) libssh2_crypt_method_aes256_cbc (181) and in the list of all methods: _libssh2_crypt_methods (298) ..or you could introduce new LIBSSH2_AES192 and LIBSSH2_AES256 flags to be set in openssl.h and libgcrypt.h respectively. In the long term I think it would be nice for libssh2 to just autodetect which crypto capabilities are available and use what is there - but there is no plan for implementing this at the moment. //Peter ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
