Description tropikhajma 2009-08-24 18:30:45 UTC

Version:            (using KDE 4.3.0)
Compiler:          Sun Studio 12 U1 
OS:                Solaris
Installed from:    Compiled From Sources

The code that is used to detect if Qt was built with SSL support (kdecore/network/ConfigureChecks.cmake) fails when the '-g' option is passed to the Sun Studio compiler. According to similar issue discussed at http://forums.sun.com/thread.jspa?threadID=5388956, some headers may be missing somewhere.

Without the flag:
$ /opt/sunstudio12.1/bin/CC  -library=no%Cstd -library=Crun    -I/opt/foss/include/stdcxx       -Qoption ccfe -features=gcc   -DHAVE_QSSLSOCKET -I/opt/foss/qt4/include   -o cxx.o -c src.cxx   
test2@opensolaris:~$ /opt/sunstudio12.1/bin/CC  -library=no%Cstd -library=Crun  -I/opt/foss/include/stdcxx   -Qoption ccfe -features=gcc     -DHAVE_QSSLSOCKET   cxx.o  -o cmTryCompileExec

I had to add '-L/opt/foss/qt4/lib -lQtCore -lQtNetwork' to the CXXFLAGS to get past the check

Comment 1 tropikhajma 2009-11-12 00:47:38 UTC

still valid in 4.3.74

Comment 2 tropikhajma 2010-03-10 05:29:04 UTC

still valid in 4.4.1

SVN commit 1101739 by winterz:

add the QtCore and QtNetwork libraries to the CMAKE_REQUIRED_LIBRARIES
when doing try compiles. 
Might fix building with -g on Sun Studio12

tropikhajma, please test and let me know if this works.
if it does, we can forward port to trunk.
