Something wrong with Irony-mode in Windows

[ramsayleung]

Hey Guillaume, I have read wiki page and I have successfully installed irony-server, but I could not get it work as expected emacs-version :

GNU Emacs 25.3.1 (x86_64-w64-mingw32) of 2017-09-13

irony-server --version output:

irony-server version 1.2.0
clang version 3.8.0 (/repo/sources/clang 1d5b05f1ef9d1b9889ddb5ad946944f224a7ba88) (/repo/sources/llvm 2aebced35905eb3891eba484e4d1902cf7399558)

this is error message:

I have tried my best to fix this error, but get nothing, Could you help me out :) ?

Have you added the location to your "libclang.dll" into the %PATH% variable?

i have the same problem: ")) (:temp-file "d:/Personal/Temp/irony-unsaved-qEjeeK" :buffer-state #s(irony--buffer-state "d:/dev/temp/Cpp-Demo-Project-For-Emacs-master/Cpp-Demo-Project-For-Emacs-master/src/main.cpp" t t 51)) #s(irony-iotask-packaged-task (:start (lambda (file line column compile-options) (apply #'irony--server-send-command "complete" file line column "--" compile-options)) :update irony--server-command-update) ("d:/dev/temp/Cpp-Demo-Project-For-Emacs-master/Cpp-Demo-Project-For-Emacs-master/src/main.cpp" 8 3 ("-x" "c++")) #s(irony-iotask-result nil nil nil nil) nil #s(irony-iotask-packaged-task (:start (lambda (prefix style) (irony--server-send-command "candidates" prefix (cl-case style (case-insensitive "case-insensitive") (smart-case "smart-case") (t "exact")))) :update irony--server-query-update) ("h" exact) #s(irony-iotask-result nil nil nil nil) nil nil))) "(error . (file-read-error \"failed to read unsaved buffer\" \"d:/dev/temp/Cpp-Demo-Project-For-Emacs-master/Cpp-Demo-Project-For-Emacs-master/src/main.cpp\" \"d:/Personal/Temp/irony-unsaved-qEjeeK \")

and with M-x shell i run the irony-server --version ,it's ok: irony-server --version irony-server version 1.4.0 clang version 12.0.0

the libclang.dll is in the path variable.

finally, i solve the problem: it's the msys2 environment which causes the issue. i install the irony-server by hand step 1,entering msys2 shell ,make sure the /mingw64/bin in the very beginning of the $PATH, use "echo $PATH" to check ,and "export PATH=/mingw64/bin:$PATH" to set it. step 2,downlod irony source from github, unzip it, then enter irony's server directory,"mkdir build",then "cd build" step 3,"/usr/bin/cmake .." step 4,install irony-server by hand by using this methon ,the binary irony-server.exe is different to M-x irony-install-server's build, and with the latter , it fails on runtime.
