Hi, I execute the following build command: $ home:rbos/kfritz> osc build openSUSE_11.2 i586 kfritz.spec The last part of the build fails, with the error attached lib/libfritz++.a(FritzClient.cpp.o): In function `fritz::FritzClient::CalculateLoginResponse(std::basic_string)': /usr/src/packages/BUILD/kfritz-0.0.1/libfritz++/FritzClient.cpp:73: undefined reference to `MD5' But when I copy the command that fails, chroot into the local build root and execute in the correct directory the build is succesful, and I obtain the executable kfritz. Does anyone know what is happening here? Why does the build fail, but can I execute the exact same command manually succesfully? The line that errors out, contains this code: MD5((unsigned char*)challengePwdConv, challengePwd.length()*2, hash); -- Richard

libssl already has a DT_NEEDED link to libcrypto (as evidenced by ldd(1)), so -lcrypto is not explicitly required. For what it's worth, I cannot reproduce this compile error using either Lbuild-jplus (osc build without the osc) or the SUSE OBS. -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

But still it is the solution. When adding libcrypto to linker line, it worked.

I use: $ # rpm -q osc build osc-0.120-2.1.x86_64 build-2009.09.23-2.3.1.noarch -- Richard -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

It is, in order for the linker to resolve external references. Philipp -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org
