[Tellico-users] I spoke to soon. Error building pre release on Fedora 10.

[Matthew Soffen (tellico)]

I hadn't realzied there is an issue.

When attempting to build tellico on a Fedora 10 machine, I recieved the
following error.


tellico-2.0pre1/src/fetch/amazonrequest.cpp:35:20: error: QtCrypto: No
such file or directory
tellico-2.0pre1/src/fetch/amazonrequest.cpp: In constructor

tellico-2.0pre1/src/fetch/amazonrequest.cpp:87: error: 'hmac' was not

make[2]: *** [src/fetch/CMakeFiles/fetch.dir/amazonrequest.o] Error 1

All the dependencies were found during the cmake process so I'm a bit
confused.   I'm a c programmer and can follow most c++ but I'm not a c++
programmer so I'm lost in how to solve this issue.

Any ideas ?

Looks like an issue with the QCA2 library. What version do you have
installed? There should be a QtCrypto file as part of the devel package.

Somehow, cmake was finding the package but not adding the correct path
somewhere, maybe? I'll try to check that.

Actually the issue is even simpler than that.

IT found the package qca-devel (not qca2-devel).

Once I removed qca-devel and installed qca2-devel ,  I found I had to
delete the build directory then re-run "cmake ." to get it to find the
path.

Now that I did this, I have successfully built the application.  Now to
test it.

Perhaps during the build you need to explicitly check for the QtCrypto
function ?

CMake is still rather new to me. I use a macro in the FindQCA2.cmake file
installed from kdelibs, so I'm not sure why that failed to check for the
correct library. It should specifically check for version 2.0 or
greater...I'll try to investigate that more.
