my cross compiler has error.tslib install but has error

[jsulm]

@MhM93 said in my cross compiler has error.tslib install but has error:

/home/fgit/libts/lib/libts.so.0.7.0
this is the lib (look for "libtool: install: /usr/bin/install -c .libs/libts.so.0.7.0 /home/fgit/libts/lib/libts.so.0.7.0" in the install log). So, you need to add /home/fgit/libts/lib/ to your pro file:

LIBS += -L/home/fgit/libts/lib -ltslib

When building in home directory there is no need for sudo when calling configure. Why do you think you need sudo?

[MhM93]

when I did not use sudo this error display:

fgit@ubuntu:~/tslib$ ./configure --host=arm-linux --prefix=/home/fgit/libts --enable-

I dont know why?
I use that lib in my .pro file

Then there's something messed up with your cross-compiler installation. You shouldn't need to be root to cross-compile.

First thing ensure that you are doing that from a clean state. Then check the complete log as to why the configure script can't use the cross-compiler properly.

@MhM93 said in my cross compiler has error.tslib install but has error:

I change .pro to this and this is the error:

What is the error?
Did you rerun qmake after changing the pro file?

[MhM93]

@jsulm :yes, I change .pro and and run qmake and then make command. the error is in the picture
@SGaist I want to run another new ubuntu to install of them from the first. all of the things need /usr/ directory should come with sudo command. so my compiler install with sudo command. I decide to do all steps again with new ubuntu. (this is my 3rd ubuntu :D ) I wish I can

[jsulm]

@MhM93 Picture sharing does not work here. Please post the error text.

"all of the things need /usr/ directory" - why do you want to have the stuff in /usr?

that is the error. when I extract the zip file they placed in /usr/local/ directory. I can not change the directory. This toolchain is https://www.mediafire.com/folder/ilkcy37otd7il/NanoPi2Board#a0l72ygtz0797 that I download and install it

[SGaist]

What does file libts.so return ?

[MhM93]

fgit@ubuntu:~$ file ~/libts/lib/libts.so

[jsulm]

@MhM93 You built it for X86 not for ARM...

[MhM93]

but I do this with my compiler path

export PATH=/usr/local/arm/4.7.0/bin:$PATH
export CROSS_COMPILE=arm-none-linux-gnueabi-
export CC=${CROSS_COMPILE}gcc
export CFLAGS=-march=armv7l
export CXX=${CROSS_COMPILE}"g++" 
export AR=${CROSS_COMPILE}"ar" 
export AS=${CROSS_COMPILE}"as"
export RANLIB=${CROSS_COMPILE}"ranlib"
export LD=${CROSS_COMPILE}"ld"
export STRIP=${CROSS_COMPILE}"strip"
export ac_cv_func_malloc_0_nonnull=yes

[SGaist]

Check the configure script options. There's something like --host=arm-none-linux-gnueabi IIRC.

[MhM93]

really thanksssssssssssssssssssssssssss
It compile without error with this command, at last.

sudo ./configure --host=arm-none-linux-gnueabihf --prefix=/home/tslib --enable-shared=yes --enable-static=no

but when I copy the exe file to my arm device it again show me this error:

@MhM93 said in my cross compiler has error.tslib install but has error:

[1]+ Segmentation fault ./helloqt -qws

This is another problem. Try to start your app in a debugger to see what happens.
Also why do you start it twice:

root@NanoPC-T2:/# ./helloqt -qws &
[1] 1409
root@NanoPC-T2:/# ./helloqt -qws

?

[MhM93]

I do not install qt creator to see debug mood in my pc, and also this program is run on nanopc-t2 when I wrote this command it returns :

root@NanoPC-T2:/# strace ./helloqt
execve("./helloqt", ["./helloqt"], [/* 20 vars */]) = 0
brk(NULL)                               = 0x21000
uname({sysname="Linux", nodename="NanoPC-T2", ...}) = 0

mmap2(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb6f67000
access("/etc/ld.so.preload", R_OK)      = -1 ENOENT (No such file or directory)
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x4} ---

Segmentation fault

Also why do you start it twice:
with silly reason. I just test what happen to run command with & and without it. :)

@MhM93 You don't need to install QtCreator to debug (QtCreator itself does not have a debugger). Just install gdb on your target device and use it. It looks like your app is running except you try to run two instances at the same time.

@MhM93 See here: http://stackoverflow.com/questions/1656891/problems-with-multiple-qapplications

[MhM93]

thanks for reply. but i just play one application.

[SGaist]

Again, run it through the debugger.

By the way, what is the exact architecture of your device ?
What Linux distribution are you running on it ?

[MhM93]

thanks for reply,
I should install debugger on my host or on my target?
this is my device:

root@NanoPC-T2:/# uname -a
Linux NanoPC-T2 3.4.39-s5p4418 #1 SMP PREEMPT Wed Mar 1 13:21:10 HKT 2017 armv7l armv7l armv7l GNU/Linux

when I run gdb on my device (nanopc-t2):

root@NanoPC-T2:/# gdb -q helloqt
"/helloqt": not in executable format: File truncated

and also when I run this:

root@NanoPC-T2:/# sudo readelf -a ./helloqt | grep NEEDED
readelf: Error: Reading 0x618 bytes extends past end of file for section headers
readelf: Error: Section headers are not available!
 0x00000001 (NEEDED)

Is that mean my header is wrong?
this is my code:

#include <QApplication>
#include <QPushButton>
int main(int argc, char **argv)
{
        QApplication app (argc, argv);
        QPushButton button ("Hello world !");
        button.show();
        return app.exec();
}
