I'm encountering an unusual error when attempting to compile DirectFB
1.5.3 for arm7. The strange thing is that this same error occurs when
attempting to cross-compile DirectFB using the CodeSourcery toolchain,
and also when attempting to compile using native GCC 4.4, 4.5 and 4.6
on the device. The error is as follows:
libtool: compile: g++ -DHAVE_CONFIG_H -I. -I../.. -I../../include

When attempting to cross-compile, I pass the following to configure:
CFLAGS="-march=armv7-a" CC=arm-none-linux-gnueabi-gcc
CXX=arm-none-linux-gnueabi-g++ AR=arm-none-linux-gnueabi-ar
RANLIB=arm-none-linux-gnueabi-ranlib LD=arm-none-linux-gnueabi-ld
./autogen.sh --target=arm-linux --host=i686-pc-linux-gnu
--enable-pvr2d
When attempting to compile on the device, the following configure is used:
CFLAGS="-march=armv7-a" CXXFLAGS="-march=armv7-a" ./configure
If anyone has any idea of what might be causing this, I'd appreciate
it if you could let me know.
Also, are there instructions anywhere on how to compile DirectFB for
arm devices?
Please let me know. Thanks,
Jake
