[SOLVED]Qt for Embedded Linux: Getting error“.obj/release-static-emb-arm/qdiriterator.o” when I make
-
[quote author="SGaist" date="1366616934"]Hi and welcome to DevNet,
Could you post a bit more of your error log ? These three lines don't say much to help[/quote]
I've reinstalled the arm-linux-gcc,the above issue is resolved.Then I reran "./configure" command:
@./configure -prefix /opt/qt-4.8.4-arm -embedded arm -no-largefile -qt-sql-sqlite -no-svg -webkit -no-3dnow -no-sse -no-cups -iconv -no-xmlpatterns -nomake demo -xplatform qws/linux-arm-g++ -little-endian -qt-freetype -armfpa -qt-gfx-linuxfb -qt-kbd-linuxinput -qt-mouse-linuxtp -qt-mouse-tslib -no-glib -I/opt/host/tslib/include -L/opt/host/tslib/lib
@
then ran "make",I got the message:@cd src/corelib/ && make -f Makefile

So how to fix it ,any help is appreciated! -
Did you also run a confclean before ? Just to be sure that there are no old compiled object lying around

[quote author="SGaist" date="1366715316"]Did you also run a confclean before ? Just to be sure that there are no old compiled object lying around[/quote]
yes I do,but still wrong.
I was told that the error was caused by gcc,some versions are very strict in syntax check.So I changed to gcc-4.1.2 and arm-linux-gcc-4.3.2.The above error was gone,but I got a new error...
I inputted the command:
@./configure -prefix /opt/qt-4.8.4-arm -opensource -embedded arm -no-largefile -qt-sql-sqlite -no-svg -webkit -no-3dnow -no-sse -no-cups -iconv -no-xmlpatterns -nomake demo -force-pkg-config -xplatform qws/linux-arm-g++ -little-endian -qt-freetype -armfpa -qt-gfx-linuxfb -qt-kbd-linuxinput -qt-mouse-linuxtp -qt-mouse-tslib -no-glib -I/opt/tools/tslib/include -L/opt/tools/tslib/lib@
then I inputted command "make",I got the error:
@

@
I found "libgio-2.0.so" in "/usr/lib",so I copied it to "/usr/local/arm/4.3.2/lib",then inputted "make" again, then got
@
/usr/local/arm/4.3.2/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.2/../../../../arm-none-linux-gnueabi/bin/ld: skipping incompatible /usr/local/arm/4.3.2/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.2/libgio-2.0.so when searching for -lgio-2.0

collect2: ld returned 1 exit status
@
then I downloaded the lastest release glib,but the error was still. I wanted to erase the libgio-2.0.so in "Makefile",but I failed to find it.
I am troubled by this problem for a few days,so how to solve it?
Best regards -
That's very wrong, you copied a x86 or x86_64 lib in your tool chain directory, you need to have the arm version.
You have to either find a precompiled version of libgio for arm or cross-compile it yourself
-
hqJma, how did you solve the problem?
I am having the same problem:
I am in the directory where my Qt embedded source files are. I do:
@./configure -embedded -opensource -confirm-license -verbose -qvfb
make@But then I get this error from make:
@.obj/release-shared-emb-x86/qtextcodec.o: In function
setup()': qtextcodec.cpp:(.text+0x23cc): undefined reference toQIconvCodec::QIconvCodec()'
collect2: ld returned 1 exit status

make[1]: Leaving directory `/home/cstjean/qt/src/corelib'
make: *** [sub-corelib-make_default-ordered] Error 2@SGalst, how do you find a precompiled version of libgio for arm or cross-compile it? I am really inexperienced when it comes to linux installations.
-
You have several possibilities, in general I try to get the same set as the one that will be on the target (debian for example)
-
Would you mind elaborating? Such as, exactly which libraries should I be installing? I know nothing about libgio. I am very much a novice to all of this.
Edit: I'm asking because I've googled things like "ubuntu libgio" and "ubuntu gio" and I didn't find something that seemed like it was obviously like what I was looking for.
-
The short version: all those you are missing to complete your build.
Go to the debian package site and search for libgio
