use of flnx

shiva_crazy02 · #1 14-Apr-2008, 07:34

Dear all,
I am using flnx 0.18.
I installed microwindows-0.90 in /home/microwindows-0.90 directory.
I installed flnx 0.18 in /home.
#./configure --with-microwin=/home/microwindows-0.90/src
#make clean;make
It compiled successfully.
When I ran demo.sh It is running.But when I ran files of "test" files of flnx. It is giving error.

e.g for hello.cxx file error is :-

Code:

/tmp/ccwCezmS.o: In function `main':
hello.cxx:(.text+0x43): undefined reference to `Fl_Window::Fl_Window(int, int, char const*)'
hello.cxx:(.text+0xe5): undefined reference to `define_FL_SHADOW_LABEL()'
hello.cxx:(.text+0x11d): undefined reference to `Fl_Window::show(int, char**)'
hello.cxx:(.text+0x122): undefined reference to `Fl::run()'
/tmp/ccwCezmS.o: In function `Fl_Group::end()':
hello.cxx:(.text._ZN8Fl_Group3endEv[Fl_Group::end()]+0x12): undefined reference to `Fl_Group::current_'
/tmp/ccwCezmS.o: In function `Fl_Box::Fl_Box(Fl_Boxtype, int, int, int, int, char const*)':
hello.cxx:(.text._ZN6Fl_BoxC1E10Fl_BoxtypeiiiiPKc[Fl_Box::Fl_Box(Fl_Boxtype, int, int, int, int, char const*)]+0x30): undefined reference to `Fl_Widget::Fl_Widget(int, int, int, int, char const*)'
hello.cxx:(.text._ZN6Fl_BoxC1E10Fl_BoxtypeiiiiPKc[Fl_Box::Fl_Box(Fl_Boxtype, int, int, int, int, char const*)]+0x35): undefined reference to `vtable for Fl_Box'
collect2: ld returned 1 exit status

My system configuration is :-
fedora 8.90(werewolf)
kernel 2.6.23/-42.fc8 on i686
gcc :-4.1.2
Thanking all of you

I solved this problem by compiling it through
:-
#g++ hello.cxx -lfltk -lnano-X -lm -o hel
It creates hel(binary file.)but when I am running it ./hel after invoking nano-X and nanowm server,it is not running .....not going to any where ....
Thanking you

Dear all,
It solved the problem little bit ......when I run following command in run.sh with "sh run.sh filename" It works.
g++ -I.. -O2 -Wall -Wno-return-type -DNANO_X -I/home/microwindows-0.90/src/include -DNANOXFOLDER='"/home/microwindows-0.90/src/bin"' -DPDA $1.cxx -L../lib -lfltk -DNANO_X=1 -L/usr/local/lib -L/home/microwindows-0.90/src/lib -lnano-X -lm -o $1
Another problem is I have to change demo.sh(in place of button I have to put filename ) code to run binary file and running it in shell as #./demo.sh
Now It works tell me sir why?
one person suggest me this but this one is also not working:-
> I'm just typing out loud here, but doesn't FLTK require you to add the

> g++ -D_REENTRANT hello.cxx -lfltk -lnano-X -lm -o hel
>
