Problems running hello example

[bogdanul2003]

Hi,

I've compiled fltk to run woth nanox and nxlib on a openwrt router. When I try to run the hello example I get this error :

oot@OpenWrt:/tmp# ./hello 

XSetLocaleModifiers called

XSetErrorHandler called

nxlib: display bpp 16, bits_per_rgb 6

XOpenIM called

XOpenIM() failed

nxTranslateEventMask no handler for event mask (00400000): 22 

XGetDefault Text background

XGetDefault fltk foreground

XGetDefault fltk background

XGetDefault fltk visibleFocus

XGetDefault fltk scheme

nxTranslateEventMask no handler for event mask (0062c07f): 14 22 

./hello: can't resolve symbol 'toupper'

Any solutions ?

Not as such: there’s a tech note on the nano/nxlib subject here

http://www.fltk.org/articles.php?L1352

But the issue you flag seems different to that.

Since toupper is a standard C library function, I’d guess you just are not linking in the right libs, or have the wrong header files in your path or something.

Are you static linking fltk? Or are you linking dynamically to shared objects?
FWIW, I’d advocate static linking, at least until you know what works and what doesn’t!

I'm linking dynamically.

I did some digging around and I found the line that gives the error. It's in the libfltk library not in the helloworld application. The file where the error happens is ./src/Fl_x.cxx at this line:  buffer[len + 1] = toupper(buffer[len + 1]);

I followed the article you posted and I modified the makeinclude and fltk-config and I attached the files so maybe you can take a look

I also set my PATH to /home/boil/Documents/opewrt/openwrt/bin/ar71xx/NewFolder/OpenWrt-SDK-ar71xx-for-linux-x86_64-gcc-4.9-linaro_uClibc-0.9.33.2/staging_dir/toolchain-mips_34kc_gcc-4.9-linaro_uClibc-0.9.33.2/bin/

And  STAGING_DIR=/home/boil/Documents/opewrt/openwrt/staging_dir/target-mips_34kc_uClibc-0.9.33.2/

Is STAGING_DIR environment variable required?

Problem solved, I was not compiling with the correct headers.

Thank you
