Linux Qt installation - useful environment variables

[linsson]

Hi all,

I am trying to install qt-everywhere-opensource-src-4.7.3 on a Linux X86_64 platform. I have all X stuff (X11, Xi, Xrender, ...) installed under nonstandard path. I usually export CFLAGS, CPPFLAGS, LDFLAGS before running configure script and it usually works but not in this case; for example:

Xinerama auto-detection... ()
g++ -c -m64 -pipe -O2 -Wall -W -I../../../mkspecs/linux-g++-64 -I. -I/usr/X11R6/include -o xinerama.o xinerama.cpp
xinerama.cpp:43:37: fatal error: X11/extensions/Xinerama.h: No such file or directory
compilation terminated.
make: *** [xinerama.o] Error 1
Xinerama disabled.

Does Qt only accept X-stuff installed under standard path? Here is my Xinerama installation:

$ pwd ; ls -R Xinerama
/usr/local/gcc/4.5.2
Xinerama:
1.1.1

Xinerama/1.1.1:
include lib share

Xinerama/1.1.1/include:
X11

Xinerama/1.1.1/include/X11:
extensions

Xinerama/1.1.1/include/X11/extensions:
panoramiXext.h Xinerama.h

Xinerama/1.1.1/lib:
libXinerama.a libXinerama.la libXinerama.so libXinerama.so.1 libXinerama.so.1.0.0 pkgconfig

Xinerama/1.1.1/lib/pkgconfig:
xinerama.pc

Xinerama/1.1.1/share:
man

Xinerama/1.1.1/share/man:
man3

Xinerama/1.1.1/share/man/man3:
Xinerama.3 XineramaIsActive.3 XineramaQueryExtension.3 XineramaQueryScreens.3 XineramaQueryVersion.3

As I said I added the include folder to CFLAGS but it doesn't work. If I open config.tests/x11/xinerama/Makefile i can read:

CC = gcc
CXX = g++
DEFINES =
CFLAGS = -m64 -pipe -O2 -Wall -W $(DEFINES)
CXXFLAGS = -m64 -pipe -O2 -Wall -W $(DEFINES)
INCPATH = -I../../../mkspecs/linux-g++-64 -I. -I/usr/X11R6/include
LINK = g++
LFLAGS = -m64 -Wl,-O1
LIBS = $(SUBLIBS) -L/usr/X11R6/lib64 -lXinerama -lXext -lX11 -lm
AR = ar cqs
RANLIB =
QMAKE = /usr/local/src/software_scientifico/qt-everywhere-opensource-src-4.7.3/bin/qmake
TAR = tar -cf
COMPRESS = gzip -9f
COPY = cp -f
SED = sed
COPY_FILE = $(COPY)
COPY_DIR = $(COPY) -r
STRIP = strip
INSTALL_FILE = install -m 644 -p
INSTALL_DIR = $(COPY_DIR)
INSTALL_PROGRAM = install -m 755 -p
DEL_FILE = rm -f
SYMLINK = ln -f -s
DEL_DIR = rmdir
MOVE = mv -f
CHK_DIR_EXISTS= test -d
MKDIR = mkdir -p

Do I need to change CFLAGS here? Is it enough to accomplish make step too? Do I need to do the same for each library not found?

Installing everything under standard path is not possible.

Thanks for your help!

Which build system are you using?

[linsson]

I am not sure I understand the question. Anyway:

I am running Kubuntu Lucid X86_64

$ uname -a
Linux ajax 2.6.32-31-generic #61-Ubuntu SMP Fri Apr 8 18:25:51 UTC 2011 x86_64 GNU/Linux

gcc --version

What do you want to build? I assume Qt, but your post does imply that you actually want to build Xinerama...

Which build system are you using to build (if it is not Qt that you want to build)? Which configure flags are you using (if it is Qt)?

[linsson]

I am sorry, it must be my English which is not very good.

I am trying to build Qt. I downloaded qt-everywhere-opensource-src-4.7.3.tar.gz and I read a page similar to http://doc.qt.nokia.com/4.7/requirements-x11.html in the doc folder. As you can see there are different libraries among which Xinerama. I installed all the libraries in the list of requirements. After that I run the configure script (./configure -v --prefix=$GLOBAL_PREFIX/qt/$QT_VERSION
-opensource) for Qt and i received:

Build type: linux-g++-64
Architecture: x86_64
Platform notes:

As you can see I have no support for Xinerama (I don't know exactly the consequences) although I installed it. I also have no support for other packages i installed; Xinerama is just an example.

If i check the configure output I can see:

Xinerama auto-detection… ()
g++ -c -m64 -pipe -O2 -Wall -W -I../../../mkspecs/linux-g++-64 -I. -I/usr/X11R6/include -o xinerama.o xinerama.cpp
xinerama.cpp:43:37: fatal error: X11/extensions/Xinerama.h: No such file or directory
compilation terminated.
make: *** [xinerama.o] Error 1
Xinerama disabled.

That's strange since I set CFLAGS and CPPFLAGS ( -I/usr/local/gcc/4.5.2//Xinerama/1.1.1/include). So I checked config.tests/x11/xinerama/Makefile and I have found Qt configuration test does not use my CFLAGS; it only search into /usr/X11R6/include.

Is there an environment variable or configure option to make qt installation process aware of dependency libraries installed in non-standard path?
