Hi Steve, I encountered a Windows OpenSSL build issue when upgrading the OpenSSL used in our product to version 1.0.1q. The error message is as follows. NMAKE : fatal error U1073: don't know how to make 'tmp32\applink.obj' I searched related articles in this forum and found the following post. http://openssl.6102.n7.nabble.com/Windows-x86-64-build-broken-RE-openssl-users-OpenSSL-version-1-0-1q-released-corrected-download-td61450.html However I was not allowed to ask my question there, so I post my question here. Hopefully you could see my question here. While I have already upgrraded OpenSSL on all our support platforms, this issue blocks me from upgrading on Windows. Under this circumstance, I could not wait for next OpenSSL release in which you have fixed the issue. I would need to put your fix into OpenEEL 1.0.1q to complete my upgrading. Would you please let me know how to fix the issue? Thanks a lot in advance, Aaron -- View this message in context: http://openssl.6102.n7.nabble.com/How-to-fix-OpenSSL-1-0-1q-Windows-x86-64-build-failure-tp62289.html Sent from the OpenSSL - User mailing list archive at Nabble.com.
