Re: [Open-ms-general] /lib64/libQtCore.so.4: could not read symbols

[Aiche, S. <Ste...@fu...>]

He Antonio,

first of all great that it works now but it shouldn't be necessary to extend the linker flags via LDFLAGS. Could you therefore provide some more details regarding your setup so we can try to reproduce the error and, if possible, fix it. Following things would be very helpful

Fedora version
OpenMS version (I assume 1.11.1)
CMake version
Qt version
How did you setup OpenMS? (self compiled contrib or system libs) ?
What was the cmake command you used to configure OpenMS?

Could you also please attach the CMakeCache.txt

Thanks a lot
Stephan

Hi all.

Please, I need to resolve this error during the OpenMS compilation
in Fedora; I don't understand what's the problem here (full log
attached):

Error fixed by adding

export LDFLAGS="$LDFLAGS -lQtCore"

before 'cmake' command.
