gmake embedded ARM build issue

[proteus1]

Hi all,

I am trying to build for an ARM embedded target with this configuration command:

./configure -embedded arm -xplatform /home/developer/Desktop/qt-everywhere-opensource-src-4.7.1/mkspecs/qws/linux-arm-g++ -big-endian -prefix /usr/local/Trolltech/qt_target

The configuration runs successfully. I now run 'gmake' and get the following error:

************************************************** **************

.obj/release-shared-emb-arm/moc_qsignaltransition.o .obj/release-shared-emb-arm/moc_qeventtransition.o -L/home/developer/Desktop/qt-everywhere-opensource-src-4.7.1/lib -lpthread -lm -ldl
.obj/release-shared-emb-arm/qeasingcurve.o: In function `easeInSine(float)':
qeasingcurve.cpp:(.text+0x7ac) :undefined reference to `cosf'

...

A lot more undefined references...

...

qline.cpp:(.text+0x1fa0): undefined reference to `cosf'
qline.cpp:(.text+0x1fb4): undefined reference to `sinf'

Some research indicates that the libm math library cannot be found. I have the arm-linux-g++ compiler installed. The following files:

libm.a
libm.so
libm.so.0

(along with many others)

Are located here:

/usr/local/arm/3.4/arm-linux/lib

Here is my PATH:

/usr/lib/mpi/gcc/openmpi/bin:/home/developer/bin:/usr/local/bin:/usr/bin:/sbin:/usr/sbin:/bin:/usr/bin/X11:/usr/X11R6/bin:/usr/games:/usr/lib/jvm/jre/bin:/usr/local/Trolltech/QtEmbedded-4.7.1/bin:/usr/bin/gcc:/usr/lib/gcc:/usr/bin/X11/gcc:/usr/local/arm/3.4/bin:/usr/local/arm/3.2.1-elf/bin:/usr/local/arm/3.4/arm-linux/lib

I've tried relocating the libm files into other directories with no luck. I've attached the Makefile for reference.

OS: openSUSE 11.3
Qt 4.7.1

Thanks in advance for any help you can provide.

Ok. My problem is resolved. I changed my configure line to:

./configure -embedded arm -xplatform /home/developer/Desktop/qt-everywhere-opensource-src-4.7.1/mkspecs/qws/linux-arm-gnueabi-g++ -big-endian -prefix /usr/local/Trolltech/qt_target

and made sure that my PATH var contained:

/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin

All is now well with Qt building.
