Invalid error caused by menuconfig: Unable to find the ncurses libraries or the required header files. (GIT8266O-861)

DaniilAlpha commented 4 months ago

Similar issue do exist, but is closed and not very relevant as about an arch package.

Environment

IDF version: d3a5f99ef8acecb3e0fbba8493aba15fa50fe375
Development Env: CMake
Operating System: Fedora 40 (6.9.7-200.fc40.x86_64)

Problem Description

After idf.py menuconfig is run, ESP8266_RTOS_SDK/tools/kconfig/lxdialog/check-lxdialog.sh reports an error

 *** Unable to find the ncurses libraries or the
 *** required header files.
 *** 'make menuconfig' requires the ncurses libraries.
 *** 
 *** Install ncurses (ncurses-devel) and try again.
 ***

Althought, both ncurses and ncurses-devel is preset on the system. After a bit of digging, I realized that error is actually not related to ncurses at all. The way script checks for ncurses presence is ~~kida lame~~ not so good, furthermore it relies on non-standard C (ommiting type before the main function), so compiler generates a warning which makes the check fail.

Expected Behavior

Menuconfig builds out of the box.

Actual Behavior

To build menuconfig, tinkering with idf scripts is required.

Steps to repropduce

May be kind of tricky, as it depends on compiler options and the compiler itself. I personaly add -std=c11 at the project-level CMakeLists, but not sure if it matters.

Fix

Adding int before this test main function fixes the problem.
