kdelibs: krandr and older xrandr version

Hello, I'm trying to build kdelibs 3.5.12 on RHEL 5 (which is getting a bit old, but still supported by RH, and widely used in companies). When compiling krandr, it fails with the following output: make[2]: entrant dans le répertoire « /home/albator/rpmbuild/BUILD/kdelibs/krandr » /bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../dcop -I../kdecore -I../kio/kssl -I../kjs -I./.. -I../dcop -I../libltdl -I../kdefx -I../kdecore -I../kdecore -I../kdecore/network -I../kdeui -I../kio -I../kio/kio -I../kio/kfile -I.. -I/usr/lib64/qt-3.3/include -include tqt.h -I. -I/opt/trinity/include -I/opt/trinity/include/tqt -DQT_THREAD_SUPPORT -D_REENTRANT -DNDEBUG -O2 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -c -o lowlevel_randr.lo lowlevel_randr.c gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../dcop -I../kdecore -I../kio/kssl -I../kjs -I./.. -I../dcop -I../libltdl -I../kdefx -I../kdecore -I../kdecore -I../kdecore/network -I../kdeui -I../kio -I../kio/kio -I../kio/kfile -I.. -I/usr/lib64/qt-3.3/include -include tqt.h -I. -I/opt/trinity/include -I/opt/trinity/include/tqt -DQT_THREAD_SUPPORT -D_REENTRANT -DNDEBUG -O2 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -c lowlevel_randr.c -fPIC -DPIC -o .libs/lowlevel_randr.o In file included from lowlevel_randr.c:23: lowlevel_randr.h:102:7: warning: no newline at end of file In file included from lowlevel_randr.c:24: lowlevel_randr.h:29: error: expected specifier-qualifier-list before 'RRCrtc' lowlevel_randr.h:44: error: expected specifier-qualifier-list before 'RROutput' lowlevel_randr.h:55: error: expected specifier-qualifier-list before 'XRRScreenResources' lowlevel_randr.h:90: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token lowlevel_randr.h:91: error: expected ')' before '*' token lowlevel_randr.h:92: error: expected ')' before '*' token lowlevel_randr.h:93: error: expected declaration specifiers or '...' before 'RROutput' [...] and so on ... (the full log is attached to this mail) It seems that RHEL5 Xrandr version (1.1.1) is too old for krandr. I have no idea of what is the most reasonable way to go: Should I try to compile a newer version of Xrandr ? Is that even possible without compiling a lot of other stuff ? Should I disable krandr in kdelibs makefile ? What will be the consequences on further compiled packages ? Should I revert all krandr-related patches to recover older KDE3 functionalities ? Thanks in advance for your enlightenment :-) Francois Andriot
