Openssl not found while compiling ffmpeg on linux x64

[beligum]

Using version 0.10 on Ubuntu Trusty. Everything works fine until ffmpeg/cppbuild.sh tries to compile ffmpeg, quitting with "ERROR: openssl not found". Any thoughts?

[saudet]

Does it look like the OpenSSL libraries and header files get properly installed? What are the last few lines of the config.log that FFmpeg generates?

[beligum]

Yes, everything seems to be installed fine.

Here's the relevant part of config.log

That's strange, it seems to think it's cross-compiling for Windows. Could you try to append --target-os=linux (or something else if that's not right) to the configure line?

[CCarden]

If you haven't, try:
sudo apt-get install libssl-dev

Hello,

(sorry for the slow response, I've been abroad)

Yes, the openssl dev package and all libs are installed correctly.

I've tracked down the problem: in ffmpeg/configure on line 4942, I had to add the "-ldl" linker flag in the first test line to make the configure script compile the ssl test correctly:

enabled openssl           && { check_lib openssl/ssl.h SSL_library_init -lssl -lcrypto -ldl ||
                               check_lib openssl/ssl.h SSL_library_init -lssl32 -leay32 ||
                               check_lib openssl/ssl.h SSL_library_init -lssl -lcrypto -lws2_32 -lgdi32 ||
                               die "ERROR: openssl not found"; }

Apparently, the -ldl in the --extra-ldflags='-L../lib/ -ldl' configure flag doesn't make it through until that library test.

Any ideas how to fix this in a good/clean way?

I see... Does that still happen with FFmpeg 2.5.4 and OpenSSL 1.0.2 (pull the latest changes)?

Just ran the same command after a fresh git clone https://github.com/bytedeco/javacpp-presets and no, still the same problem. Here's my gcc version:

I've found the problem: We need to use the --extra-libs option to specify additional libraries, and that's working here. Check the commit above, let me know how that goes, and thanks for reporting!

[saudet]

Fix included in the -0.11 release. Thanks your time reporting and investigating this!
