[gentoo-user] Constant compile error with different programs

Hi,

currently I am playing around with gopher and want to compile
a gopher client myself, which is not lynx.

Unfortunately, the three I tried to compile myself fail to compile all
with similiar symptoms like this:

gcc -g -O2 -Wall  -I.. -I.. -I../object  -DNOBANNER -DCTRLCPROMPTS -DCONTROLX   -DGOPHERLIB=\"/etc\" -DGOPHERHELP=\"/etc/gopher.hlp\" -DGLOBALRC=\"/etc/gopher.rc\" -DREMOTERC=\"/etc/gopherremote.rc\" -c upload.c
gcc -L../object -o gopher manager.o gopher.o globals.o ourutils.o cso.o subprocs.o html2.o CURcurses.o gopherrc.o download.o pager.o form.o upload.o  ../object/libgopher.a  -lcurses  -lcurses -lm 
/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: CURcurses.o: undefined reference to symbol 'nodelay'
/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /lib64/libtinfo.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:152: gopher] Error 1

It seems something wrong with my *curses* installation, which is
missing symbols which are identified while linking.

Is there any chance to compile such programs successfully?
What could be the reason for this?

Cheers!
mcc
