There is quite old uClinux-dist-20080808 with uClinux-dist-20080808-20090112 and uClinux_on_stm32 patches for STM32F10x MCU, as described here AN3012.
I use Ubuntu 18.04 (inside VirtualBox) to build uClinux and go through AN3012 step-by-step.
So, I run "make menuconfig", enter settings as shown on page 15 (AN3012) and then exit menu. There are a number of messages in terminal and finally I got this:
configuration written to .config
make[ 2]: Leaving directory '/home/maksim/Projects/STM/uClinux-dist/config' make[ 1]: Leaving directory '/home/maksim/Projects/STM/uClinux-dist' make[ 1]: Entering directory '/home/maksim/Projects/STM/uClinux-dist' Makefile:228: *** mixed implicit and normal rules: deprecated syntax

Please help to understand what is wrong and fix it. Many thanks for any help!
Notes for those who want to reproduce the issue:
1) you need to fix the uCLinux-dist/kconfig/config/zconf.hash.c (insert the snippet below at line 165)
#if defined __GNUC_STDC_INLINE__ || defined __GNUC_GNU_INLINE__
__attribute__ ((__gnu_inline__))
#endif
2) uClinux uClinux-dist-20080808 is available here
3) uClinux-dist-20080808-20090112 patch is available here
4) uClinux_on_stm32 patch is available here here
The solution is to use older Linux version. Ubuntu 12.04.5 is OK.
Do not forget to add CodeSourcery /bin folder to PATH.
