Using QCA Encrypt Library with Qt >5

SGaist

Hi and welcome to devnet.

Which version of OpenSSL are you using to build QCA ?

Hoehli

Hi ;)

i'v tryed multiple versions:

1.1.1b
current master branch of the git repo
1.1.0k

SGaist

Just to be sure, I would check against the latest version of the 1.0 series.

Hoehli

So, finally I build openSSL(1.1.1b) with minGW and got the corresponding headers.

At the QCA CMakeList there is the macro: "OPENSSL_INCLUDE_DIR" i've set the path and it's working.
But how can I link/set the Path to the openSSL lib?
Somehow it's not compiling qca-ossl.cpp because of the missing lib.

best

ok, tried it with openSSL 1.0.2r, finally i'm getting ONLY one error while compiling qca-ossl.cpp:

line 5810 :

sessInfo.isCompressed = (0 != SSL_SESSION_get_compress_id(ssl->session));

undefined reference to SSL_SESSION_get_compress_id

SSL_SESSION_get_compress_id

Strange, that method is supposed to be available since 1.0.1...

Can you find it in the headers of your installed OpenSSL version ?

Hoehli

Yes, it's defined in ssh.h which is included.

I also have trouble to include the 64bit build of openSSL: while compiling qca-ossl.cpp i'll get a alot of undefined reference errors.. using the same mingw64 compiler

SGaist

Might be a silly question, but are you sure you are linking to the right version of OpenSSL ?

You might be hitting a cmake cache entry.

Yes, think so :D. I included C:/openSSL32 for 32-bit, and C:/openSSL64 for 64-bit, that's the path I put my compiled openSSL.

To compile openSSL (version 1.0.2r) I used MSYS2 and followed this discription. The minGW compiler I used was the one, shipped with QT at: c:/Qt/Tools/mingw530_32 for 32-bit and C:/Qt/Tools/mingw730_64.

Configured the openSSL with the perl script with this options:

./Configure mingw shared no-idea no-mdc2 no-rc5 --prefix=/c/openSSL32

and for 64-bit:

./Configure mingw64 shared no-idea no-mdc2 no-rc5 --prefix=/c/openSSL64

Between those two steps I restarted MSYS2 and reconfigured the PATH variables to the corresponding minGW compiler.

I also tried the mingw-w64 compiler (he didn't made it).

You might be hitting a cmake cache entry.

32-bit version: https://pastebin.com/2VYa47f0
64-bit version: https://pastebin.com/4x0Sn5Xm

If I'm comment the line 5810 (of qca-ossl.cpp - Version 2.1.3 of the QCA) out, the dll's are build and it's working (somehow but probably unstable).
Thanks for the support! I appreciate.

Edit:

I had a deeper look into the CMakeCache files:
at the 64bit-version i changed the Value for LIB_EAY from C:\Program Files (x86)\Intel\iCLS Client\libeay32.dll, to C:\Program Files\Intel\iCLS Client\ssleay32.dll.

This reduced the undefined reference errors, now I only get the same error as for the 32-bit version at line 5810.
YAY -> one step away :D

man, that's pain on windows... on Arch Linux QCA compiled "out of the box"...

Edit2:
tried the current master branch of openSSL (1.0.2s) still the same error.

Hoehli

no more ideas?

SGaist

Rather than replacing the library, did you try link them both ?
