./gnuplot: can´t resolve symbol 'png_pass_ystart'

./gnuplot: can´t resolve symbol 'png_pass_ystart'

[Niko Lau]

Hello,

I have a custom board based on the at91sam9260 with a handmade linux system.
I'm now trying to switch to a oe system.
I went throught the getting started and made the helloworld program (with
uclib), which worked fine on my board.
After that I built gnuplot. When I try to start it on my board I get the
above error.
Sounds for me like a missing lib, but libpng and libgd is on the target.
Has someone a idea what the problem is?

THX

Hi Niko,
You might try 'strace gnuplot' to see exactly what's failing at run 
time.  Even if libpng is installed , you might get a missing symbol 
error for png_pass_ystart if you've built against a different version 
than what's installed.  I'd guess just building gnuplot in oe without 
first building the libs it needs is the root cause.  You could check 
your gnuplot build log to make sure headers from outside oe are not 
leaking in somehow.

If libpng is left over from building your pre-oe target file system, you 
should rebuild everything using oe.

Good luck,
John

Hi,
I built gnuplot statically then it worked fine.
There is something messed up with my handmade rfs. If I switch completly to
oe it should work also with dynamic libs.
Thanks.
