[Solved] Program with QCA library crashing on other computers
-
I'm trying QCA library, specifically AES encryption, everything's working fine on computer with Qt SDK, but when I try to run program on other computers, it crashes. I don't know if i'm missing some dlls, or there's some other problem. I have qca2.dll in program directory, qca-ossl plugin in crypto subdirectory, I have dlls from openssl library.
Does anybode have any clue?

You will have to provide more information.
What does "crash" mean? Are there any error messages or stack traces?
Did you accidentally ship a release version of your application with debug libraries or vice versa?
-
here's screenshot:
!http://macav.panacom.sk/crash.png!i've tried also debug version and release versions, i didn't combine them. Are there some dll dependencies other than openssl dlls?
-
just one more thing, when I run qcatool2.exe, it says "Cannot load library qca-ossl2.dll: The specified procedure could not be found."
-
Are you sure that you aren't mixing different library versions?
-
Okay, I made it work :) Previously, I used binaries downloaded from qca site, now I tried to compile latest 2.0.3 version, then qca-ossl plugin and it's working.
thanks

Hi,
i followed all the steps given in the below link
http://www.essentialunix.org/index.php?option=com_content&view=article&id=48:qcatutorial&catid=34:qttutorials&Itemid=53.firstly, I am able to compile latest qca 2.0.3 and able to call library functions in Qca.
Second, I am able to compile and make qca-ossl2.dll..but i am unable to load the this dll.( that y i m not able to call aes, rsa, and other block cipher algos)this the error i m getting when i using the qcatool2.exe
qca-ossl2.dll: failed to load: The plugin 'C:/QtSDK/Desktop/Qt/4.7.4/mingw/plugins/crypto/qca-ossl2.dll' uses incompatible Qt library. Expected build key "Windows mingw release full-config", got "Windows mingw debug full-config".if possible please explain installation procedure how u compiled qca-ossl dll
OS:
windows : version 7
QT version: 4.7.4
Qt creator: 2.3.1

well, according to the error, I guess you're combining release and debug builds. I Built QCA and qca-ossl2 as both debug and release. I used "GNU Make":http://www.gnu.org/software/make/ but i think that's irrelevant .. procedure is in README/INSTALL files.. i did something like this:
QCA:
configure --debug-and-release
make
installwinqca-ossl2:
configwin rd
qmake
make
copy lib*.dll qtdir\plugins\crypto

hi,
I followed all the steps mentioned in the above post. but still i m unable to load qca-ossl plugin. when i m using QCA::supportedFeatures().. this is the following response (sha1", "key"random", "md5", "storelist")
-
do you have dlls from openssl in the folder where exe file is? i'm not sure, but i think the necessary are ssleay32.dll and libeay32.dll
-
still not able to load the plugin
-
I ran out of ideas, check one more time that you have all necessary files in the folder with exe, and qca-ossl2.dll in subfolder "crypto" ..
if you're still not able to load the plguin, you can try openssl library directly, without qca

i also followed all the steps given in the below link
http://www.essentialunix.org/index.php?option=com_content&view=article&id=48:qcatutorial&catid=34:qttutorials&Itemid=53.i can using the QCA's funtion,when i deploy the nessary dlls and exe to other computers.
