Win 10 make error liblto_plugin-0.dll

[ThomasB]

Hi,

I tried to install the toolchain and IDF on a Win10 machine.

esp32_win32_msys2_environment_and_toolchain-20170330
ESP-IDF fresh download (21.07.2017)
set ESP-IDF path in msys
(Works fine on my Win 7 machine)
downloaded the hello world example
changed serial port in menuconfig
make from msys

AR libbootloader_support.a
C:\msys32\opt\xtensa-esp32-elf\bin\xtensa-esp32-elf-gcc-ar.exe: Cannot find plugin 'liblto_plugin-0.dll'

I tried
*clean build
*build from eclipse (with my win7 settings) and with msys2
*Replace native PATH in eclipse with msys paths
*run msys as admin
*add msys to PATH
*remove all conflicting mingw installations from PATH
*reinstall toolchain and esp-idf
*try different projects
*restart the machine
*get coffee and think about the meaning of life

[perryc]

pulling latest esp-idf broke our win10 boxes too

in $IDF_PATH/make/project.mk around line 293 change "gcc-ar" to be "ar" seems to work.

looks like xtensa-esp32-elf-gcc-ar.exe in the build system is missing some dependencies.

[rudi ;-)]

one of the latest updates in ESP-IDF got a change
confirm: win7

Cannot find plugin 'liblto_plugin-0.dll'

best wishes
rudi


edit: problem and solution in the meantime is on github
