+❯ make сборка не работает. собери проект 
+
+● Давайте посмотрим на структуру проекта и попробуем собрать его.
+
+● Searched for 2 patterns, read 1 file (ctrl+o to expand)
+
+● Попробую запустить make и посмотрю на ошибки.
+
+● Bash(make 2>&1 | head -100)
+  ⎿  Package x11 was not found in the pkg-config search path.
+     Perhaps you should add the directory containing `x11.pc'
+     to the PKG_CONFIG_PATH environment variable
+     … +20 lines (ctrl+o to expand)

+● Нет компилятора g++. Проверю, какие компиляторы доступны.
+
+● Bash(which g++ gcc clang++ clang 2>/dev/null; g++ --version 2>&1 || clang++
+      --version 2>&1 || echo "No C++ compiler found")
+  ⎿  Error: Permission to use Bash has been denied. IMPORTANT: You *may* attempt
+     to accomplish this action using other tools that might naturally be used to
+     accomplish this goal, e.g. using head instead of cat. But you *should not* 
+     attempt to work around this denial in malicious ways, e.g. do not use your 
+     ability to run tests to execute non-test actions. You should only try to 
+     work around this restriction in reasonable ways that do not attempt to 
+     bypass the intent behind this denial. If you believe this capability is 
+     essential to complete the user's request, STOP and explain to the user what
+     you were trying to do and why you need this permission. Let the user decide
+     how to proceed.
+
+
+
+
+
+● Сборка не работает потому что:
+
+  1. Нет компилятора g++ - команда make: g++: No such file or directory
+  2. Отсутствуют X11 dev-пакеты - pkg-config не находит x11, xext, xft и др.
+
+  Для сборки нужно установить необходимые пакеты. На Ubuntu/Debian выполните:
+
+  sudo apt install g++ libx11-dev libxext-dev libxft-dev libxinerama-dev \
+      libxcursor-dev libxfixes-dev libxrender-dev libfreetype6-dev \
+      libfontconfig1-dev libcairo2-dev libpango1.0-dev
+
+  Или, если хотите собрать без Cairo/Pango (минимальная сборка), нужно изменить
+  Makefile, чтобы отключить эти зависимости.
+
+  Хотите, чтобы я:
+  1. Помог настроить Makefile для минимальной сборки только с X11 (без
+  Cairo/Pango)?
+  2. Или подождём пока вы установите пакеты?
+
+❯ минимальная сборка без Cairo и установи зависимости сам мне
