error while loading shared libraries: libncurses.so.5 [SOLVED]

Hi

I am developing with STM32CubeIDE which comes with its own build toolchain.
The problem is if I try to debug my application it runs this command:

/home/p/st/stm32cubeide_1.2.0/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.7-2018-q2-update.linux64_1.0.0.201904181610/tools/bin/arm-none-eabi-gdb --version

which gives me an:

error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

I already have "multilib/lib32-ncurses 6.2-1" and "lib32-ncurses5-compat-libs-6.1-2" installed, but still it cant find the "libncurses.so.5" file.
Whats the problem here?

Re: error while loading shared libraries: libncurses.so.5 [SOLVED]

Why is it resolving the 64bit libs for libm and libc?
Is this a 32bit binary?
Does it need an extended LD_LIBRARY_PATH to look at /usr/lib32?

Re: error while loading shared libraries: libncurses.so.5 [SOLVED]

I dont know, I am not very deep into that library stuff.

I tried this to force the binary to look into lib/32:

# LD_LIBRARY_PATH=/usr/lib32 st/stm32cubeide_1.2.0/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.7-2018-q2-update.linux64_1.0.0.201904181610/tools/bin/arm-none-eabi-gdb
