RE: OpenSSL on beagleboard
Thanks for helping jeff, but it haven't worked yet. I searched my libssl.so in my /usr/lib and I didn't find. Does someone have any idea? I have installed the libssl-dev, libssl0.9.8. Thanks for helping.

RE: OpenSSL on beagleboard
From: owner-openssl-us...@openssl.org On Behalf Of Paulo Roberto Sent: Monday, 27 August, 2012 18:37 Can no one help me? Isn't there a way of specifying the local the openssl is installed? You mean location i.e. in the file system? As far as I know packages on most Linuxes, including ubuntu, install into system standard locations, maybe something like /usr/lib or /opt/ssl . System locations vary for different Unixes but are usually the same for different libraries on the same Unix, so you might be better off asking people who know about ubuntu in particular. If it is in a standard location, your gcc (assuming your gcc is the correct package of gcc for your Unix) should find it. If you have some kind of nonstandard perhaps experimental package, and you know where it is installed, -L/path/to/libdir is the gcc way to specify additional library directories. (The -Ldir must occur before the/any -llib that's lower-ell that needs it.) You always need to make sure you *compile* with headers that are compatible with the library(ies) you *link* with; if you are linking with libraries in a nonstandard location you may need -I/path/to/incdir that's upper-eye (for gcc) to find the corresponding headers. I'm not sure if -I must precede the sourcefile(s) but I put it there for clarity. And if you have a non-package build, such as one you did yourself from source, both of these (-L and -I) are much more likely.

From: owner-openssl-us...@openssl.org On Behalf Of Paulo Roberto Sent: Monday, 27 August, 2012 20:21 Okay, this time you did post the error. When I use the command gcc teste.c -lssl -o teste: /tmp/ccyvrO2i.o: In function `main': rsa.c:(.text+0x8): undefined reference to `BN_new' snip many more BN BN_* are in libcrypto not libssl. Another attempt: ubuntu@omap:~/arquivos$ gcc rsa.c -Wl, -lssl, -lcrypto -o teste /usr/bin/ld: cannot find : No such file or directory /usr/bin/ld: cannot find -lssl, collect2: ld returned 1 exit status That's closer, but you've mixed up two different things. -Wl,x,y -- comma(s) and NO space -- passes opaque linker arguments, like -Wl,-Bstatic in a previous response. -lxxx is not opaque (driver knows it) so don't use -Wl . You do want -lssl -lcrypto (space but no comma). Any idea? If you need both SSL and low-level routines like BN_*, use -lssl -lcrypto . If only need low-level, just -lcrypto . If you need both depending on your linker order may matter, in which case -lssl should be first. I haven't found the libssl.so in my directory /usr/lib. Then that's (probably) not the right location on your Unix/distro. If it is dynamic, on Linux at least, ldd should work. Do ldd `which openssl` and look to see where libssl.* and libcrypto.* are. __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager majord...@openssl.org
