[SergeySlice]

macOS Sequoia x86_64
GNAT Studio from https://sourceforge.net/projects/gnuada/
Compiler from https://github.com/simonjwright/distributing-gcc/releases/download/gcc-14.1.0-x86_64/gcc-14.1.0-x86_64-apple-darwin21.pkg
it is the latest release for x86_64.
The compiler works in Terminal

sergey@iMac GNAT_studio % gprbuild -Pproba
Compile
   [Ada]          main.adb
Bind
   [gprbind]      main.bexch
   [Ada]          main.ali
Link
   [link]         main.adb
sergey@iMac GNAT_studio % 

with the project created by the GNATstudio.
But the GNAT Studio can't compile the project because on _iconv dependencies

gprbuild -d -P/Applications/1App/GNAT_studio/proba.gpr /Applications/1App/GNAT_studio/src/main.adb
Compile
   [Ada]          main.adb

Is it possible somehow use $PATH/libiconv.dylib instead of assumed?
