Problems of cross-compiling Qtopia Core 4.3 for ARM
Message 1 in thread
Hello,
first, thank you for reading my mail.
i cross-compiled qtopia core opesource 4.3.0beta for my PXA270, my cross-compiler is 'armv4l-unknown-linux', i have no idea whether the problems relate to my compiler.
when it compiled the file src/corelib/kernel/qvariant.cpp some warnings occured, following is the compiling message:
armv4l-unknown-linux-g++ -c -pipe -fno-exceptions -O2 -Wall -W -D_REENTRANT -fPIC -DQT_SHARED -DQT_BUILD_CORE_LIB -DQT_NO_CAST_TO_ASCII -DQT_ASCII_CAST_WARNINGS -DQT_MOC_COMPAT -DQT_NO_DEBUG -D_LARGEFILE64_SOURCE -D_LARGEFILE_SOURCE -I../../mkspecs/qws/linux-arm-g++ -I. -I../../include -I../../include/QtCore -Iglobal -I.moc/release-shared-emb-arm -I.uic/release-shared-emb-arm -I../../include -I../../include/QtCore -Iglobal -I.moc/release-shared-emb-arm -I.uic/release-shared-emb-arm -o .obj/release-shared-emb-arm/qvariant.o kernel/qvariant.cpp

.......
(some other similar warnings, no error upon)
and then:
make[1]: *** [.obj/release-shared-emb-arm/qvariant.o] Error 1
make[1]: Leaving directory `/root/qt/qtopia-core-opensource-src-4.3.0beta/src/corelib'
make: *** [sub-corelib-make_default-ordered] Error 2
the compiling process terminated!
please help me, and tell me what's wrong.
thank in advance.....
