Error generating exe in ubuntu 22.04

[Vlademiro Landim]

Hi all

I'm getting this error :

Generating C source output to '/tmp/hbmk_p4z0t3.dir/hbmisc.c'... Done.

/usr/bin/ld: /usr/local/lib/harbour/libpng.a(png.o): undefined reference to symbol 'floor@@GLIBC_2.2.5'
/usr/bin/ld: /lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line

collect2: error: ld returned 1 exit status

Harbour compiled in Ubuntu 22 + PostgreSQL access

gcc --version

gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

harbour --version

Harbour 3.2.0dev (r2307062207)

Any idea ?
